Technology Connections would like a word.
Send this to Alec, please.
my first thought when i saw that jacket.
I would love a Collab between them
Linus does a solid cosplay
my first thought. :) A collab between LTT und Terchnology Connections would be great.
I spent most of my life servicing CRTs, CRT projectors, and other consumer electronics. I -know- what's causing the cloudy display here, and it will improve overall intensity as well as dramatically improve clarity -- it's algae growing in your coolant. It causes localized groups of cloudiness, an overall dingy washed out image, and if you look into the CRT and move around you can see a parallax effect because it's between your eyes and the surface of the CRT. Most CRT projectors had a coolant reservoir sealed against the face of the tube, to reduce heat and allow them to crank up light intensity without suffering burn-in as quickly. This coolant is not circulated, and MANY MANY MANY models suffered growth in the chamber. It was believed to be contamination in the production and assembly process. The repair process is theoretically simple but can be complicated because of how packed together that model is -- on every single model, there is a rubber boot with a cap holding it down, to allow thermal expansion. Orient the boot upward, remove the cap, empty and flush the chamber with 99% isopropyl, and replace it with CRT coolant. Remove ALL AIR from the system (NO bubbles, POUR SLOW) and reassemble with the boot pushed in a little, to allow for expansion as mentioned. MG Chemicals still sells the stuff, on Amazon. The "water cooling" parts you highlighted were actually the very thoroughly wrapped and potted HV components for the CRT. I would sincerely love to provide my knowledge to help you guys out!
As a cinema projector technician, I can 2nd this suggestion as a likely cause. Similar things tend to happen with older xenon bulb projection since they too use water cooling. Past that I can say that relic is far past my expertise, and HUGE respect to @FuchsDanin for having the know-how to work on CRT and older entertainment electronics. You guys are like wild west pioneers to us rookies still in the field.
This is me, searching button to give trophy for being awesome, and only buttons are like and report 😅
Never had one, didn't lived back then, but very interesting, and kind to share.
Thank you folks.
love how even mainstream "techfluencers" attract experienced repairmen. please make some videos to preserve this knowledge please :)
Yeah when I saw how dim the image was I knew it needed some love. I've seen people fix CRT monitors for arcades that were also very dim and muted, I figured it probably needed some caps and to be reflowed. I didn't know there was coolant in there, that's rad.
That's awesome. Such cool technology, even the problems are interesting. I hope they take your advice.
Oh that would be so cool to see Dan work on the projector! I love watching people work on old electronics.
Pro tip: you can "overclock" a CRT easily by increasing the voltage on cathode heater. It will pull more current and be brighter. It's the safer method than increasing the voltage, because it's about 25 kV already, and vacuum tubes tend to emit actual X-rays when fed with very high voltage.
I used to work on CRT projectors and your method is NOT recommended unless you want to burn out an irreplaceable CRT filament. Raising the H.V is a safe method but id shortens the life of the CRT.
@@mrgcav Increasing heater voltage won't burn out the filament anytime soon, it will still last at least several thousand hours. The cathode will wear out much faster which is the real problem.
Raising the high voltage is unsafe because of X-rays. Also it can cause arcover which can physically snap the tube's neck. Some early 70s Zenith TVs notoriously have this as a failure mode when capacitors on the flyback circuit fail.
@@mrgcavWell, you're quite right about the damage potential. I should've mentioned that I've only heard of this method being used to revive old CRT TVs that would otherwise go to waste anyway, due to being just too dim from old age. I'm not so sure about the voltage though. It is away to do it, but i don't think either of them is safe. Not unless equipped with a dosimeter and radiation-proof lead undies, LOL. I really believe that the possibility of irradiating yourself and everyone nearby is far more dangerous than just damaging some old tech. It may also be a bad idea to destroy something so rare and unique that may belong in a museum one day. But a generic CRT TV would just be hazardous e-waste at this point.
to further increase the brightness those projectors were usually combined with super-high-gain silver screens. They deliver around 2.5 x the brightness when setup properly, but of course came with sacrifices like major hot spotting. But since the screens weren't exceptionally big anyways, it wasn't that noticeable as it would by todays common screen sizes.
Why would we not want to see geeky videos like Dan fixing the 80s SONY CRT projector? Hell yes we do!
I'd like to see how it looks with a new tube and a lens upgrade. I bet the lens is terrible if it only cost $3000.
The rrp on the cheapest Sony crt projector from the 90's was $12,000+.
Absolutely would love to see this!
Hells yes!!!!
Nah sounds boring not on the main channel pls
or get 12voltvids they showed repairing one in the video to come in since he's Canadian as well
Dan fixing CRT projectors with the right to repair+ booklet? That sounds amazing!
right to repair :thumbsdown:
I want to see water cooling upgrade
@@12Rosen K my man go buy your 3rd Iphone 20 in a row because 3 droplets of rain dropped on the screen
@@12Rosen lol cringe
i dont even use iphones. right to repair is an overreach of the government's power.@@machintrucGaming
My father brought a CRT 'projector' to our home in 1994. It was a projector module that you could put in any compatible CRT. It enabled us to watch world cup that year and it was totally usable. After that I used to play games and watch movies using that 'projector'. It was a great experience.
@6:23 to be fair they used what appears to be a parabolic metallic screen with extremely high gain. In the Sony video it mentioned the VPS-60 screen with a gain of 19, which means perceived brightness will be 19X compared to a white wall.
i love new episodes of Linus overpays for ancient hardware you've never heard of, such a great show.
I love when he makes annoying sound effects as he's playing a game to over-compensate for the fact that he doesn't even like gaming.
@@rBennich L
Thorough the magic of buying _two is them._
I love LOFAHYNHO, my favorite show
I would subscribe to that channel.
I used to have a Vidimagic. When used with a curved retro-reflective screen, it was actually pretty good. Flat on a wall.... NOPE.
BTW, that cloudiness is caused by fungus growing inside the coolant chamber in front of the CRT. This was a common problem that was fixed by flushing the coolant and replacing it. Many projectors and projection TV's would get this after many years. Cool tech in the 80's..... because we didn't have anything better. BTW, when I tried to buy the service manual from SONY, they wanted $2600 for it. I had them check again... that was NOT a typo!
They seem to have less problems than rear projection TVs from that era. I remember those going out of tune after just a year or two of regular use.
@@AdamsOlympia Yes, keeping 3 tubes converged was an art! They drifted a lot.
I would absolutely love to see Dan fix this. Solid Floatplane content, maybe?
@@AdamsOlympia Rear projection used 5 inch tubes are were built to hit a consumer price point. As said, drift was just one of their problems. Professional CRT projectors were typically 7 inch minimum, and had much better build quality, with a pricetag to match. The pro 9 inch models were the absolute best by the late 90s; I've been running an Electrohome 9500 Ultra for the past 5 years and it hasn't needed much re-calibration. Just basic convergence adjustment during warmup, which I have digital profiles for. Drift only happens with major ambient temperature changes, or from bumping one of the tubes I don't have bolted down 😆
@@AdamsOlympia The fact that this uses a single tube means there's no need for convergence adjustments between tubes. By using a color CRT these problems are eliminated except you the shadow mask/aperture grille means you lose picture quality and brightness. Monochrome tubes always look better. I think the obscure Indextron here is brighter than a standard color CRT but the beam detection system necessitates poor black levels.
The old guy that does sound editing, here's a tip for you, you don't need to hear the sound when fixing it, you can also see it thus eliminating the high frequency from the CRT.
IT MADE ME GO NUTS.
Almost everyone under 25 can hear it but 35 year olds almost certainly they can't.
Anyhow love you guys at ltt ❤
this ^. i literally got dizzy from the high frequency whistle
That noise used to drive me nuts whenever someone had a CRT on in the past. I don't hear it in this video..but I wouldn't have expected to over CZcams.
agreed, makes it a very uncomfortable watch.
Getting dizzy? Don't be ridiculous. I'm 36 and can still clearly hear the 15kHz noise a CRT generates. How do you think we "old people" grew up watching TV or playing video games on CRTs? Nobody got dizzy... you guys are snowflakes.
@@knortn just because you don’t have an issue whit something doesn’t mean it’s not a thing. And the “we did not have a problem whit it” is surely because you got used to it and could filter it out. This is a common issue these days and is very fixable. Tom Scott made a video about it a while back.
This video just reminded me of some 90s tech I worked with. I was working in IT for a business consultancy company and we looked at some laptops for our consultants that had a screen you could fold out to put on an overhead projecror (OHP). From what i remember they worked well, though the risk adverse consultants generally took hard copy of their presentations printed on acetate just in case.
Why even ask? OF COURSE you should repair vintage tech you pay a fortune for! Show us the best it can be!
And stick a super bright bulb inside that would never have existed back then. Please.
@@jamesrael9557 The CRT makes the light, there is no bulb
And through the magic of buying two of them...
or rather: "through the magic of someone else buying two of them..."
He bought 7 in the most recent video.
@@rightwingsafetysquad9872He bought 7 HVAC units?!?!
_Jazz intensifies_
I see you are a fellow Technology Connections fan.
Just to be clear, high-end CRT projectors were over 1500 lumens and last generation super bright CRT monitors over twice as bright as most WOLED displays, and on a par with current QD-OLED monitors, it's also brighter than plasma displays, only DVLED and RGB-OLED has greater average nits.
I appreciate that even the audio quality was lower in the opening segment to really sell that old tech feel
(09:15): Correction: That is NOT water cooling, That is an epoxy-covered High Voltage circuit for the video output tube (note the potentiometer attached just to the left of it)
It is cooled with ethylene glycol but yeah that isn't it. Whoops
Came here to say this. Thank you.
It’s amazing how affordable great projectors are compared to just 20 years ago
You mean 40 years ago right?
@@cianmiller8592They mean the segment at 12:50
Hell, even just compared to 10 years ago.
Right?? I found a 4k one for less than a grand and it doesn’t even have any wifi or apps to steal my data and sell it to make up the difference.
@@GabrielSykes I bought an Epson 3lcd projector 8 years ago for €660 (basically same as $)... It was just a normal price, no big discount or anything. Granted, not quite 10 years ago but I don't think it makes much difference. When I look at what's available now I'm really not blown away, prices are about the same, specs are a little better but not as much as I would expect in 8 years.
I used to install and service some of the last & most expensive and massive CRT projectors as LCD was appearing. They were horrible to setup an image. It could take more than a day if you were merging more than two on a single screen. They could also easily kill you. First the sheer weight of the things (we used a 20 foot CO2 powered telescopic hoist), and when you were running them with the covers off, some tasty voltages were available in an instant.
What an absolute time capsule! Fascinating to see the retro tech, and even more so to understand how far we’ve come in terms of brightness and resolution.
Where's the Technology Connections collab I thought was coming 😭
Awesome video either way 😂
Nah the video is only 15 mins long, about 2 hours too short to be Technology Connections 😂
I love how these guys post before I even take another breathe❤
That would be a Floatplane exclusive. After all, they do have extended videos on their platform.@@peanutismint
A deep dive tech connexions fp exclusive collaboration would be kinda cool.
I think last time there was a shout-out to Alec's channel the fans weren't so nice
I love the authentic slightly scratchy audio and 4:3 aspect ratio in the opening.
And I just realized that jacket looks a LOT like TechnologyConnections so that's extra thematic appropriateness.
Scratchy audio definitely not authentic.
I want to thank you, your videos are the only reason I haven't walked into traffic. My motherboard died on my pc and your videos are the only thing that are keeping me sane while i wait for work to pick up. I appreciate the work you do and what you bring to the tech space
stay positive and out of traffic my friend! 🙏👍😊
@@Y2Journey it's hard to stay positive when everything seems to be falling apart around you and you don't have any real way of taking your mind off of it, the depression sets in hard and fast
its amazing to know ive kept good care of my hearing, linus pushed that button and i could still hear the CRT whine even at 39
Save this link and revisit that comment in about 5yrs, and see if things have changed... Old age catches up with you quickly. ;)
Yes, would love to see Dan trying to repair these! Love this classic tech
Imagine Dan and Alec collab. 👌
This vintage edit is really good damn
the 4:3 ar is a nice touch
I need to know how it was made. it's freaking perfect.
@@appc23it only works with Linus.

@@almanac520 It is the aspect ratio that fits my monitor 🙂
First the FW900 now this!! watching my dreams play out in front of me and not having the ability to own this is tough. Until then, I will continue to watch LTT and at least experience it this way. Thanks for the hard work and dedication, guys. -a fan
The highpitched CRT noise when you turn it on at 1:50 is just the cherry on top that made me smile...
You may wonder how I'm old enough to know the noise and young enough to hear it... but I am young... I'm 20... but I lived and grew up with a big CRT TV and the noise bring me great joy of watching cartoons and playing xbox 360 on it.
Thank you, Linus(and the crew!)
Why did i expect Technology Connection to pop in at the place of Linus head?
They got Dankpods and he lives in Australia. PLEASE Alec is so much closer!
The high frequency noise as soon the projector is turned on, despite all my memory on CRT TV from the 80/90 I do not miss this pitch !!
Nah I love it, it's literally the electron gun going "PEWM!" inside the tube haha
And a high end VGA CRT looks lightyears better and doesn't produce those annoying sounds.
@@saricubra2867 Sony Trinitron FTW
Im 13 and I cant hear it, its hard to hear when theres audio, and you get used to it
thank god other people can hear it, I thought I had tinnitus
I didn't realize how much i missed the high frequency noise a crt makes until i heard you power this thing up.
Dan doing any repairs on camera is something I want to watch. Love Dan. Thanks, wonderful WAN producer.
The cameraman did amazingly well to deal with so many lighting changes and still give us not only a good image, but also a look into the projector at the same time. Shout out to whoever was on the camera! Major props!!
Did not expect this kind of nice, earnest comment from a guy using Mario doing a goatse as a profile picture.
Doing a gostse? Yeah, I'm not zoomin in. @@BalthorYT
I would watch all 1-3 hours of a Technology Connections/LTT collaboration video. You know it'd be a long one, but it'd be SO good.
How have they not collabed yet
Bought my first video projector at the beginning of the 90s. It had 50(!) ANSI, you needed absolute darkness to see anything. But still was a blast for gaming.
I want nothing more in life, than to watch Dan fix this old projector
I love it when you guys cover vintage stuff, please do it more often. Also, a colab with Technology Connections would be a dream come true.
You guys need to collab with Tech connections for videos like this.
Im almost sure it's the same coat as a reference
Lol i really enjoyed that intro, great throwback with all the classic effects and everything
Of course we want more Dan on camera. Always more Dan.
Dressing like technology connections in the beginning made me smile :)
He did it another time but I forget the video.
In the 80's, I actually _created_ a projector with a small TV set to max brightness, the lens from a large magnifying glass, a cardboard shell whose interior I'd blacked out with a giant black marker to reduce glare (only slightly successful since it made it black, but shiny), and a mirror, so I could project a pretty crisp image onto the ceiling of my darkened bedroom. Aside from being inverted, it worked great. I didn't want burn-in though so I only used it for a little while. It was a fun proof of concept.
@LTT pls make this a video!
@@stonybaboonUsing stripped down LCD panels on old overhead projectors was thing in around 2010-2015, before good projectors got affordable. Then laser projectors came out.
It's actually pretty easy to invert the image if you really wanted to, all you had to do was swap the polarity of the deflection coil wires!
@@redpheonix1000 True, but 19 year old me didn't really know anything about electronics. Or anything else. 🙂
I did consider using a mirror to deflect sideways before deflecting up towards the ceiling, but I just didn't have the materials or the energy to make a more complicated rig like that.
BTW I projected onto the ceiling because my walls were typical teenager walls with stuff plastered all over them, so the ceiling was the only good projection screen. 😜
@@christopherlenahan3906 Ooo, I never even thought of that. I did see people making DIY projectors from old laptop panels with super bright backlighting, a mirror, and a lens, but an oldschool overhead projector is such a perfect fit that they were really wasting their time building a rig of their own. Neat!
My grandfather had one. He was a missionary and used it to show videos at gospel meetings in rural Bolivia. I remember it was always pretty dim but back in the day it was mind blowing! Especially for people who may have only seen a TV or a movie a handful of times. I was too young to understand the workings of it but I remember they ran it from a 12v battery that gave it just enough time to run a 15min video.
CRT projectors I’ve worked on in the past used glycol to create a wet lense. It would grow bad things in it over time. You can clean out and replace. You will regain clarity and brightness. Awesome unit
As someone who currently works on CRTs daily, I just wanted to clarify that when the editor's note at 7:10 states that past the 1980's, "single gun CRTs became more common." This isn't correct. Pretty much every CRT outside of the indextron and monochrome CRTs used 3 cathodes to produce a full range of color up until the very end of their production. I hate to be a stickler, but I work on these things so darn often that the, "um, actually" part of my brain kicked in. This video was still super fun and informative though! I'd love to see Dan work on one!
Do you only work on projector crt tvs? All other crt displays are one gun with the phosphor mask having the 3 colors.
The design made color tvs compatible with black&white TVs and broadcasting in the US while also keeping them as compact as possible.
@@crazywright83 I work on and own both CRT TVs and discrete front projection CRTs like the VPH-D50Q from Sony. The phosphors mask you’re talking about is actually a solution to the problem of having three individual cathodes (or “guns) in a color CRT. They needed to create a way to “guide” each cathode’s electron beam into a distinct color slot on the front of the display otherwise the image would appear wildly misconverged. If you ever saw the neck of the tube in a CRT TV while it’s operating you would see three distinct glowing cathodes close to the neck board, one for each color. The compatibility for b&w TVs during the era of color TV signals was more or less handled by the way that the TV demodulated chrominance and luminance from the incoming signal, with b&w TVs only decoding the luminance signal.
@@crazywright83 I own and work on both CRT TVs and discrete front projection CRT projectors, like my Sony VPH-D50Q. The phosphor mask that you mentioned was actually developed as a solution to the problems created by utilizing three distinct color cathodes, or "guns", in color CRTs. The phosphor mask effectively acted as a "guide" for the electron beams coming from each cathode to ensure that they would land in the proper position on the front of the tube. Without this mask the picture on a color CRT would look wildly misconverged. If you ever have the chance to see the neck of a CRT's tube while its running, you will notice that there are 3 individual glowing cathodes near the neck board, these are the 3 color cathodes in action. As for compatibility with B&W televisions during the transition to color television signals: this compatibility, to my understanding, comes more down to the signal being transmitted and how the TVs demodulate the signal as opposed to actual picture tube differences. Color video is composed of luminance and chrominance, and instead fo decoding both, B&W TVs would instead decode just the luminance in order to maintain compatibility.
@@crazywright83 CRT TVs and these 3 Tube projectors are a completely different thing. The likely reason for using 3 tubes, instead of one... was because it would allow for greater overall brightness. THREE sources of light combined... vs One.
With a CRT shadowmask, you dont need to worry about brightness levels... because you are not Projecting the image +15 feet away.
My only thought for this would be that Plouffe or someone else read something on the Trinitron wikipedia page or similar, and sorta fell for Sony's marketing of "using a single gun".... Which in reality is still 3 separate cathodes, just with some shared bits supporting them.
hell yeah i wanna see Dan try and fix it, old tech disassembly and repair is like my favorite YT content and it would be awesome to see it on this channel with your guys' level of video production
I enjoyed this. Thank for making this.
I used to have one of these back in the early 90s. The picture was definitely brighter than shown here. I used it exclusively for gaming a Sega Genesis and NES. The Betamax worked, too. I had only one tape. It was Return of the jedi. It even had a remote. Found it at a flea market for only $20! It got used a lot in a dark basement where it was pitch black. It truly was like being in a movie theater. We even had a standing theater style popcorn machine and VHS player with tons of movies to watch.
That blur is called lens fungus. It happens in old camera lenses aswell. It happens between the glass layers, so to remove it you need to do a full lens deconstruction.
I have worked on a few of those. The common failure is Screen control on the voltage trippler (that thing close to the thing potted with red goo). The symptom is all white screen. By moving the control you can get the picture to come in. Once it is clean and working consult the service manual for proper adjustment. If the beam current is not correct the beam indexer is not getting pulses.
Also, once a speck of dust got onto the fragile Digital Micromirror Device (DMD) module, it caused permanent black or while pixels, just like burned out pixel on modern LCD/LED displays.
Love the Technology Connections refernces here!
MORE TECH LIKE THIS !!!! thank you Linus !!
Missed Chance to Collab with technology connections
Wait this isn't Technology Connections
Man can have several channels. this is clearly connextras.
He wishes.
fr, he stole his jacket
We had a non portable crt projector when i was a kid in the early 80s. The screen was 5 or 6 feet, but the projector was huge. Going off memory, it was about 3-3 1/2 feet tall, 2 feet wide, and 3 1/2 long/deep. It had to be positioned about 6-8 feet from the screen. However, it was bright enough to use with the lights on or even with sunlight coming in through the sliding glass door. Of course, it looked better in the dark. We had it for years until the color tubes started going. As stated in this video, there were three of them. It was too expensive for us to replace it back then. If i recall correctly, I was told it was about $1,200 per tube, so $3,600 just for the parts. Not sure if tax was included and if the work could be done ourselves or had to higher a technician.
Its so dim that I want to see you guys fix the second one & try to focus them both on the same spot with the same video source on both. like the RGB projectors but, CRT
Please no dropping
That's quite an ask for Linus
don't drop things or shave your beard
Linus :
bruh why, he has to drop it for views
Is it a impression of Alec? I just love it! This video is on point!
The opening had definite Technology Connections vibes.
I LOVE the "Technology Connections" look and vibe!
Someone donated one of those to my church when I was in high school, in the late 90s. We used it to do movie nights. Yes, it was hard to see even at night time 😂. It came with an external Avon speaker, I brought in my Panasonic Bookshelf speaker system, which I had splurged on the surround sound version. Fun times!
that's the technology connections jacket!
oh my god that high pitched whine when you turned it on i forgot that was a thing. i do not miss it. i will be hearing that for DAYS now
I do not miss it either. Cant believe i was able to tune that out in the past
I was wondering if it was some editing error or my desktop amp, but I forgot about that awful crt whine
@@josec1756 I wasn't able to tune it out when it was there; Now that it's finally gone, I'm too old to hear it anyway! =:o1
Keep up the good work ltt
A coworker of mine would go to ham radio fests with his dad. This would have been the mid 90s probably. It was old then but his dad picked up one of the 3 tube projectors fixed it and flipped the image so it sat on the floor. Using a Sega Genesis on that was a dream back then.
It's amazing that thing works, and that you actually found a fully functional unit WITH video, amazing. (Yes I was a kid in those days, and I had the honor of setting up 3 crt Barco projectors), and I can tell you...that was ...cumbersome. that unit you have there, would have been a dream for us.
I follow some folks that refurbish old Arcade Video Games, and reconditioning old CRT's seems like something that can be done with the right tools. I've seen some remarkable results.
As someone involved in the CRT community, and who plans on restoring a few of my own CRTs soon, it's actually insane how well you can fix up old ones, the tips and tricks ive been told by old timers that have done CRT repairs for decades are fantastic
Back in the day you'd buy two projectors and align their pics over top of each other to bump brightness. It helped.
Speaking of LAN parties, when I have them I play on my projector's 142" screen. When I take off in the helicopter in Battlefield, it makes my stomach feel weird, like I was really taking off lol
Yes I want to see Dan try to fix it. I want to see if the burn it is on the lens or the tube. Also want to see if the water cooling needs a refresh.
The Vidamagic FP-60 is like a blast from the past, and it's fascinating to see how far projectors have come since then. 🤯
Somewhere in storage I have a prototype Zilog webtv box. I swear I’m the one who gave the idea to Dr sack and my grandpa.. I kept saying I wish I could have internet on our big screen.
It was wayyyy to ahead of its time. We were still using dial up lol. They did get it to connect to a server with a landing page type thing. And it was about the size of a smaller blue Ray player.
Epicly Real Comment That Totally Wasn't Piped Through ChatGPT
settle down bots, settle down.
Yall are killing it on quality. Super impressed with what the team is putting out
Absolutely we want to se Dan trying to fix it, and make it a long one, a deep dive and all that fun stuff.
I actually made one in early 2000 with a lense from an overhead projector and two carboard boxes, taped to an old Sony CRT from my Commodore 64! Worked greaking great in dark conditions! Watched many a WWF pay-per-view with my friends on that baby!
Congrats on Technology Connections getting hired at LTT
Can you imagine, we used to build vidi-walls, large scale video screen where each screen held a 3 tubed CRT projector. Sometimes many dozens of projectors in one image.
It took 1-2 days to just adjust the convergences of each RGB CRT set.
And the power draw was often in the 63-125Amps 3 phase for a not too large of an image !
how many watts would be that many amps? that's gotta be thousands right? especially 3 phase, thats a ton of power
Dudes, the fact you initially went with Super Mario 3 is amazing. I grew up with a dream of playing Mario 3 in a theater and when I finally got a projector it was the first thing I hooked up. Y'all are on the wavelength!
I had the same one, purchased in the late 90's for about $400 (at Defcon!). Mine had a BetaMax player on the back.
i like how linus in the first part of the video was dressed kinda like the guy from the Technology Connections youtube channel
The old promotional video also shows it being used with a special screen on a stand. That was surely a gain screen, which would have added a bit of additional brightness. But even given that and the fact that the CRT would have been brighter when it wasn't 40 years old, you weren't going to get a good experience with that projector in a normally lit room, any more than you did when the old projectors that I saw like the Advent Videobeam, the Kloss Novabeam, and a Pioneer model that had the projector under the screen and used a mirror to reflect the image back to the screen. All of those required a darkened (though not pitch black) room for a good viewing experience. (All of those used three tubes.)
They had these in my elementary school when I attended. They’d play movies in the gymnasium on an occasion or two. The dimness, and blurry spots are exactly as I remembered them being 30 years ago, or more. 😊
Hey guys, that's probably NOT burn-in. More like bake-in. There is residue on the glass panel that either on the glass the phosphorus is mounted on or the inside of the lens. Looks vaguely hand print shaped, so probably hand oils that have been baking for 40 years.
Clean it with 90% alcohol

In my early 20s I had a bunch of friends that lived in an art gallery/DIY music space and they had 2 CRT projectors donated to them. The mass majority of the hours I spent playing San Andreas were on a Sony CRT projector.
I grew up with a Barco CRT and laserdisc as a kid. The whole naiberhood cane home to me to see T2 back in the early 90s. Great to grew up with a tech savy dad :)
I want to see the two crt projectors working together to see if they can produce a brighter image
Fun fact. You could make these out of an old CRT, cardboard and a lens. Simply make a box around your existing CRT and put the lens in the center of the cardboard. Then pull the lens closer or further away to adjust the "focus".
This sound like a great and feasible 3D print project for the guys at LTT.
Stop saying fun fact
Remember seeing ads in popular mechanics for a lens kit. They would optionally sell you the video inverter if you didn't want to flip your tv on its head
Nope. So even worse brightness and mirrored. And the worst screenshapes. So not fun and no fact
@@girlsdrinkfeckfun fact
lol, I just saw a CRT projector at the thrift store. It was a Mitsubishi vs-1250. No idea if it was still working, and I didn't have time for another project.
Even so, I had no practical reason to get one, even if it was in working order.
Love these old tech videos.Dan needs to attempt the repair!!!
Missed opportunity for HDR!
This definitely should’ve been HDR…
Loved this episode. Brought back great childhood memories. I had an aunt that had the same projector in her penthouse around 1984. I thought it was the dopest shit.
For Christmas 1989 my parents bought my sister, her boyfriend, and me a Sony Watch Cube. We first saw them on the Navy base exchange store in San Diego but my parents went back to buy them and they stopped selling them so they wound up buying them at department store in Tijuana Mexico. It always smelled like it was going to burn the house down and always ran really hot.
Linus definitely knows how to keep up with the trending algorithm. Really timely vid, riding that trend wave hard.
Imagine linus drop this projector
I would love to see the repair video
Awesome! Was just talking about this last week at work! I'm in Japan and one of my crazy stories from the past that really impacted my boss and co-workers was that I drove 8 hrs each way to buy a TV. Not just any TV - this very same Sony projector! I was reading a newspaper left behind on a train and found the Sony in the For Sale in the Want Ads. It was a Friday, I believe. Called the number - OK. Called a friend and said, "Wanna go on a road trip tomorrow morning?" And off we went to Portland, OR. Crazy times. JP boss & co-workers were astounded that anyone would drive that far for anything, much less a TV. For Japanese people, a two-hour drive is FAR away (easier to just jump on a train and be done with it).
I would love to see Dan test his skills by fixing one of those projectors. He's a great host on camera too, so it would make for a great video.
Did you borrow that jacket from Technology Connections?
As a kid in the 90s I remember making my own projector from my CRT monitor turned upside down, an inspection lamp with a magnifying glass and some bin bags. Used to project a program called Acid Warp on my bedroom wall as well as playing DooM - except the controls were inverted if I remember right. Happy days.
How big?
My hospital was getting rid of their ampro projos back when i was in med school in the 2010s so i lugged one of them and a screen home. coolest thing about them? Light guns work! Playing house of the dead 2 on it was magical
Literally want nothing more than for a big vid on Dan trying to fix one of these! 👍
Thanks for the high pitched noice the moment the projector was turned on, very presistent and not at all annoying.
