Great tutorial! Where does the yellow red white go on a tv that has green blue red component?
how do you do the weather
It's so strange how they went from making crap like this to, at the very end of production of VCR's, upgrading to a somewhat better, if not still flawed, design. I have three EoL Funai based VCRs ranging from 2004 to 2016, one being a standalone VCR that does everything you'd need a VCR to do, and another being merely a HiFi version of this (it isn't all that good apart from being a decent CD player). Though, the 2013 - 2016 version is different in a lot of ways, but it was clearly made to withstand time a lot better than these due to it's rather sturdy metal body and frame, supports DVD and VCR playback through a modern HDMI cable, and it's VCR seems to be a lot less likely to eat tapes than these super cheap ones from before 2013 (not to mention VHS HiFi was standard). I can say at the very least, despite having this crappy period of ultra cheap combo units, Funai didn't end their VCR production on a sour note.
This has the added benefit of an RF amplifier operating in common base mode, thus a low input impedance and high gain. If you're in the middle of nowhere this radio will work where others won't. (Your first radio that you recapped). They gave those radios like the Prominent away as a bonus when you signed up for Columbia House record club.
Did you ever "update your method"? Have you made or can you make a video detailing best ways to do this? I have tons of old tapes with commercials on it from my country in my language (PAL), and I was wondering what the best way to do this was. Also maybe mention what tapes are the best and the differences and such? Since you mention it shortly in this video i mean :)
Actually sony head cleaners can be cleaned and put back together to have a second life. Note: let it dry after because if you do it wet, the vcr will screw up your tape
Bought one of these recently at a garage sale, worked when first plugged in and tested but now the docking station has power but nothing to the VCR. Any thoughts on what to check?
Hope you can find a donor machine or even a new pinch roller for your machine. Certainly worth fully restoring. Maybe another unit with a donor display too, lol.
Baycrest tv is very sick
I have the same tv, but the audio thing is the only annoying fact, bc if the audio is perfect, then the image looks horrible
It's always the caps. Even if it isn't. Or if it is a Sanyo from the early 2000s, then it's those small white plastic wheels in the winding mechanism.
Wow, that was our first VCR back in '88, brought back good memories. Thanks!
Wow I had the HS-337EZ 10 years ago. It was exactly the same as this. I literally found it a few meters away from my house laying on the street. It had all kinds of toys inside, probably from kids inserting them through the cassette slot lol. I remember it doing the same thing with the tape going in and then immediately ejecting. After a few tries it worked a treat, then I replaced the reel drive belt and then I sold it. :D
That's why I always beep out capacitors in the faulty section of the circuit... I got an amplifier in for repair that had one channel bad and using one of those STK hybrids. I measured through the inputs and outputs and couldn't find the fault so I ordered one of those STKs. Which didn't fix it. After many many more hours of troubleshooting (the majority of a day) I found one shorted cap. The only one I must've overlooked when testing them all.
Great video! I used to work on these in the late 80's. Very difficult to fix. Panasonic's were alot easier to work on.
What Doctor show is this on the tape? 15:57-16:17 and 22:56 - 23:05 (from the BASF EP Tape)
Amico ottimo video,sono felice che lo hai sistemato,il VHS merita sempre una chance,grande!
Done the same - renamed to Salora for EU market - all caps were dead for sure, all rubber belts become goo as well :) IPA will not clean goo, better to use something like sticker removal
@@Kirill_Maker Lighter fuel or kerosene cleans this stuff really good.
i had the same issue with national VHS player, and yup the caps were leaky, i replaced a few with what i had and the audio came back but quiet. it seems i need to recap every cap on my vhs to fix that.
It's always the caps, even when it's the belts, it's the caps... :P
Especially those light purple ones
My family’s cottage also has a PV-V4630-K VCR that’s silver and it works much better than this. I guess you got unlucky with that one.
dang what a collection. I would've lost my mind having something like this in the 90s
That video now dvd player only works on video now dvd discs what happens when you put original dvd discs into the video now dvd player
How do You choose in wich tv channel (ch 2,ch3) does the programming Will show up
A Japanese masterpiece of the 80s
My beloved cassette recorder ❤️
I bought a second hand one same like that it was in perfect condition _ original made in Japan _ I was deeply in love with this RX _ even though I had a bigger more modern Kenwood HiFi system but this one was really something special to me _ ❤❤❤
How can a sensor register special effects on a film roll? Very interesting.
It would be a nice VCR, if it weren't for that pitiful rewind/fast forward speed. My "portable" HITACHI from 1982-ish(?) is faster. Edit: Memorex was a good blank media (various tapes, CD-R, DVD-R/+R) manufacturer. Dunno what they're doing (if anything) today. For quite some time, it's JUST a brand.
my parient bought that VCR so they can make copies of tapes that they rented, this is the first VCR with remote control otherwise the very first VCR had wired controller.
Regalenme. Una de. Esas. Bellezas.
You know what I always say about letting tubes wake up lmao. The Baycrest (reminds me of National made sets) may just have a crusty cathode with how low hours it looks Surprised the EHT on the electrohome didnt arc over into all that dirt. Both look like they’ll clean up well though
I have a baycrest tv of that exact model though the plastics are a different colour,
The person who invented that machine is a genius ❤
Nice CRT's, that wood one can probably be salvanged and cleaned up.
I plan to run them for a while to see if the CRTs wake up. But if they don't they're basically useless. The picture in real life was so dim and washed out, so I would never get a watchable picture from it. The camera makes it look a lot brighter.
Peaceful greeeeeeeeeen!!
Dirty TVs for dirty movies I guess... :P
There's nothing discussing about dust or a little dirt dude....grow up JR!
That Electrohome TV has a corresponding MGA badged model in the US, so it is a "real" Mitsubishi (I guess the company in Singapore is either a contractor working for Mitsubishi or some sort of Mitsubishi subsidiary). And CPT=Chunghwa Picture Tube, which I think was part of Tatung. The Baycrest is a Fujitsu-General just like the other one on your channel, though made in Taiwan instead of Japan.
I just passed by a 17" Compaq CRT monitor, looked like it was in good shape.. certainly cleaner than that pair, but then again it had been left out in the rain. I wanted to pick it up, but alas. No space and well, I couldn't repair them if they needed repair. Very cool to see that Canadian Electrohome brand. Sounds super futuristic. "ELECTROHOME". Your home is now electric.
This is an awesome project! Would love to do something similar with WeatherStar and a small CRT. Might do something like this but with virtual machines within Promox with a shared hardrive. For all of the channel content, did you rip those tv shows to 480p? Curious of the quality since I mostly have 1080p movies and would have to source over the air quality stuff to get that same feel.
Hey guy, when this JVC VCR was in production all other brands had the same amount of cheap plastic parts as did this JVC. So im not sure where you were going with your cheap comments. If you want sharp video..go to dvd players like i did. When I make transfers from vcr to dvd I don't use a computer of any kind. I simply got to a dvd recorder from the vcr. No need to by any kind of converters. Using converters degrades the video signal. Going direct from vcr to dvd recorder gets the best picture quality. I found the JVC VCRs S-HS series produces the best quality picture for transfers...period. I've tried Sony, Panasonic, Samsung,Phillips vcrs less quality of picture. I don't record on vcrs anymore like I use to starting in the early 80s. I used a Sony vcr to record a lot of shows from my old analog C/Ku band satellite system. Recording raw wide feeds. I had the GI 650i receiver.
It's crappier build quality than the older JVCs, that's what I was getting at, and I stand by it. If you read about these Dynamic Drum models on old forum posts from when they were new, there's tons of complaints. Regarding capturing, DVD recorders just add an extra step for me, since my end goal is files on the PC. But I've since moved back to Hauppauge cards (currently using my old HVR-1800). The converters are convenient and usually provide an ok picture, but they throw away a lot of detail and very often crush bright or dark scenes completely. The only upside is they seem to do a really good job stabilizing video from bad tapes. To the point that I will have jitter on the CRT monitor, the output of a TBC, but the cheap converter will look rock solid. So I do save them for the really bad tapes - the "40 year old EP recordings on grocery store branded tapes that were stored in a basement" kinda recordings.
@probnotstech ...ok you got some explaining here, what did you mean by Hauppauge card? You lost me. I'm not into today's computer terms. I don't own a PC or a Laptop. I don't read old forum post about this JVC vcr or the HR-S3500U unit because I had the units when they were in production. I never had problems as you indicated about the head drum. I got 8 good solid years of trouble free service from these vcrs. They have the best bright, crisp clear picture then the Sonys and Panasonic. I even own one of the first commercial vcr in the early 80s I had a RCA unit. This unit was one of those top load models.
It's a tuner/capture card that goes inside a PC (model # is HVR-1800). They were originally sold as tuner cards so you could use your PC as a DVR (using Windows Media Center or similar software). That's what I used mine for about 15 years ago. Luckily it still works on my current PC. The card also has a composite and s-video input, that is useful for digitizing analog video. It's great that yours worked without problems. I'm just relaying my experience with this VCR, and what I read regarding other peoples' experiences when they were relatively new.
Cool
First of all you don't connect this type of a vcr to today's flat screen. You won't get a good quality picture. Today's tvs can't handle standard definition. Your best bet is to get yourself a good Sony crt old school tv and connect this vcr and you'll see a big difference in picture quality. If your going to watch a lot of movies from a vcr..connect the original format tv..4:3 ratio Tv!
By the way you don't view this or any vcr to a LCD screen. That's the worst way to see the video.
That was just some tiny TV I used for testing on my bench back then. Didn't have room on the bench for a colour CRT to sit there permanently. I can assure you, I wouldn't be watching movies on that horrible little thing lol
How to increase tv resolution to use effectively Chromecast 3 or adjust ratio?
I bought a Panasonic branded device and it had an incredible quality, everything was great, but it did not read the tape and got stuck there. I couldn't find the solution and I messed around and unfortunately I damaged the heads and it turned out to be waste. Later, I found the solution, I solved the problem by pushing the tooth manually, but it was too late. I'm still very sad, it was a great device.
I’ve built this exact thing on a raspberry pi b+ and every 3 or 4 episodes it stops and just goes back the the Kodi homepage
I've had that happen befor and it's usually a bad video file. I've found Kodi is super picky about damaged files. Unfortunately I don't know an easy way to determine which file causes the problem.
@@probnotstech are you sure because there seems to be a pattern of about 4 videos then off
@@ifanjenkinator3464 Not 100% sure, no. That's just the problem that I had. Yours could be many things. Maybe a flaky pi, memory card or USB. Try another power supply, or try replacing the video files with different ones to see if the problem still occurs.
How often should the video and/or audio heads be demagnetized, if ever?
I've never heard of someone demagnetizing video heads in a VCR. The head drum is aluminum and the cores are ferrite, so there isn't much to become magnetized. I suspect you could risk causing damage by attempting this. The stationary heads (full erase, control track/audio, and audio erase) could become magnetized over time, but I think if you use the VCR to record periodically it should be fine. All of these heads will be fed a signal when recording, which should demagnetize them (my understanding is the AC bias signal should work to demagnetize them).
What channel is this ? And is it on vhf witout digital connection?
I was using an old analog (low power) TV transmitter that was just off-camera.
Hey Probnot, I have a sony SLV-776HF which is identical to the 775HF. When I insert a tape, the machine's capstan moves the tape for around 5 seconds, then ejects. There is no video and when play is pressed "PLEASE INSERT A CASSETTE" appears. All buttons on the front panel lose their functionality, including eject. I haven't found anything online to help, service manual and user manual are dead ends. Any advice?
