Tektronix TDS 744A teardown and repair 2
I continue working on the 1990s Tektronix TDS744A digital 4-channel 500 MHz oscilloscope. My plan was to fix the colors, but I ended up taking a closer look at the switching power supply board, testing and replacing a lot of high ESR electrolytic capacitors, fixing a board damage from electrolyte leakage and relubricating the fan. I did some experiments with the sequential color system. The color shutter has no voltage going into it. There's definitely a problem in its driver, but the shutter itself might be deteriorated too. For now, I decided to remove the color shutter. This gives me a bright monochrome picture. The oscilloscope is perfectly usable this way. I might try to put the shut...

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). The next episode: ruclips.net/vid...

Dobrá Čengliš 😅
Great video. Thanks.
Yes... Debunked.
Great video. Thank you.
The accent😂😂😂😂
Thermal dynamics 101. Asynchronous motors as a generators do work until a load is placed with these in box thinking designs, Fun to watch and just browsing channels for my time machine parts.
Don't call your self a wild animal, you're genius. i lerned electronics from you!
What a mess trying to open that thing up why do they go to so much extremes to keep you from getting inside ? or is it better to do that for the life of the components? And what kind of accent is that ? Is that your real voice lol
Chinese watts are measured in grams.
I like the more extensive videos; if people don't want to watch it, let them be. I'm sure more people like to watch videos in depth!

a 68w fast charger retail for at least 15 USD, therefore a no name brand for 3 dollars you have to know it is not real and what to expect.
What is that crappy overshoot on square waves? That don't look right.
Nice.
8:46😂😂😂
@9:32 - "crapacitors" (a new word for crappy capacitors) - Ha! Ingenious! :D Congrats on the funny wordplay. :)
Thats why u buy meanwell power supplies and other decent chargers...
This era of Tek scopes from the 90s are notorious for having bad caps everywhere, I've rebuilt a TDS 420A and a TDS 540 and it was the same issue and some were leaking. I ended up just replacing all capacitors throughout the scope, probably around a hundred of them. Not a difficult repair, but time consuming and expensive. These scopes are not bad for what you get, if you can get used to the clunky, lagging menu/interface design.
Please make more of this type of content 😅, your newer content are boring
your accent makes it seem like you're constantly singing no offense
You should als check the 5V rail capacitors for leakage. They might be leaking as well.
its a me, mario
Great video. Thanks.
Why cant he use soldering iron
"Post apocalyptic capacitor"😂😂😂
If you have a short persistence of vision, as I do, these colour shutter displays are hideous. Horrible flickering display, great way to trigger a migraine. I can't believe they ever released this product.
All people have about the same persistence of vision, but some are more easily annoyed by the effect sequential color displays create when they move their eyeballs rapidly. It might be annoying, but it gave it a better resolution than a tiny color CRT would have.
should expose the seller’s page
Ok
part 3 pls😝
The metal part is perfect instead 🤭
I prefer it without the filter on. Btw, it's almost always elec capacitors fault..

It will protect your smartphone from too high charging currents, your battery will last 10 years.. before being charged 100%
A very dangerous field to play around in. Get the screening wrong and you will literally cook your flesh. Best to leave to experts, and this video is NOT from an expert so.SCAM, SCAM, SCAM.
I like your accent
I wonder if the color board is removable then the firmware might know something about detecting it? thus unplugging it might make the display more sensible for a monochrome scenario
Why would some one design such a psu ... which is not at all efficient
Watching you solder with that sledgehammer of a soldering gun expecting total incineration I must say: Best solder job I have seen with the tools given Imagine what you could accomplish with a proper soldering station!
The scary thing is there are literally hundred or thousands successfully sold by one seller alone online and proper reviews from customers who bought them are as nonexistent as the truth inside this charger
Supercool
re soldering "iron", as a wise one once said 'all ways are good, except the bad ones"
WHY DO HP LAPTOPS HAVE THIS PROBLEM
