Tektronix TDS 744A teardown and repair
What's inside a 1990s Tektronix TDS744A digital 4-channel 500 MHz oscilloscope, fixing it. One channel has a huge DC offset. The monitor has some problems - the colors are not working, it shows weird dissolving circles. It's a CRT-LCD hybrid - a monochrome CRT tube with a solid state sequential color filter (liquid crystal color shutter / LCCS / LCS / NuColor).

Fake OpAmps from eBay, how to test OpAmps
zhlédnutí 17KPřed měsícem
Testing suspicious LT1006CN8 and TLE2141CP operational amplifiers from eBay. How to test the output voltage swing (low and high state output voltage) and the common mode input voltage range. These are obviously fake and both behave exactly the same, despite having a different marking and coming from different sellers. The output voltage swing is quite poor on the negative side. The common mode ...

Another IMRC module repair - tricky this time

Trying to fix another Ford IMRC (Intake Manifold Runner Control valve) module. This time it's not so easy. A tricky situation when it doesn't work, yet all components appear good. UPDATE: It was reinstalled and it worked, so either the lubrication or resoldering the questionable solder joints helped.

You have to drill in those unwanted leds !
This $3 charger is impressively crap. I did get a Red therapy light, which was pretty good from AliExpress. But after seeing this, I think I would think twice before buying from them again.
I bought a power bank of eBay, Third of it was packing foam and it was one third of the quoted capacity, got my money back and got to keep the power bank

I have and been using the 2 dollar uk type 18w charging adapter with digital meter for the past 5 month, nothing kaboom yet execpt constant buzzing sound when it turn on 😅
How the hell did you put your hand in hot water
Where are you from dude? Tou accent very different
The beauty of those old machines is that you can repair them. Most of the times you get the circuit diagrams too.
Hi what thermal camera do you use?
I am wondering why, even though I am subscribed, I stopped getting the videos in my subscription page (and homepage). Then I see ~230k subscribers and even 1y old videos with only 10% views compared to subscribers. That's a pretty low subscriber view rate. CZcams is doing something lame here (in addition to servers side injected ads now...). This looks like the only vid with over 100k views from last year.

I am actually using this exact charger. It does the job for normal/slow charging. However, I always unplug it when I'm leaving the house, lol

Hello. What parts are shocker chocolate chips made of?
Hello. What electrical parts is the chip made of?
Big Clive - Swedish Chef edition?
That scope has a lot of options. All displayed on power up. I have a 784 and the color display is very nice. There is a fellow on eBay selling replacements for the NVRAM chips, around $100. He recommends replacing all those small electrolytics.
You are so funny dude, instant subscription
Nice.
nenatahuuuj to taaak prosiiim těěě
You should try to pass 10 or EVEN MOAR amps through it )
Hvala.
What a garbage product. Thanks for this informative video.
Congrats! Keep going!
My extension shows 109 people downvoted this. CCP are working hard to keep their lies hidden :D
just found your channel really underrated you need more subs. Great channel Subbed!

That must have been expensive when it was new

Why tin whiskers in pre-RoHS device?
What do you think solder is made of? Hint Tin & Lead.
@@Brian_Of_Melbourne Sure, and you need pure tin for whiskers. Where they care for reliability, they put 3% led, and get no whiskers.
dude. you are very good at teaching. thank you.
Great video. Do you have an updated video series ready? It's been 4 years since this one.
I wonder if these dangerous products are sold in PRC or are just for export.
3 bucks for 5v / 2a Nice :p
give it back to me you thief..👽
I always stay away from chargers with multiple ports. Experience shows having an open port while charging increases the risk of shorts significantly. Its a sign to me that the engineers didn't put much thought into its design. A few years ago, I stay away from the whole brand who will do that until everyone seems t be doing it.
Chinese always fakes ! They can just cut copy paste!!(Ccp)
But marking on pcb CY1😂
6:40 😂😂😂 bloody hell! I laughed so much. that is really hot, i wonder how it didn't fried by being on for 3 hours.
Good grief! What an absolute space ship indeed! So much MECHANICAL engineering. Just compare the chip count with a modern counterpart - amazing
