Lol its not that special, just a monochrome VGA like signal with H sync and V sync going into a monitor. The 22khz vsync is an oddity but otherwise its mostly direct connections to a VGA plug.
The line amp There is a very bright horizontal line in the middle of the screen? Or possibly vertical? Again, it's a big transistor that heats up that passed the weapon to the left. Changing it often brings the TV back to life
Ahhh. soon you will learn that it's never the chip :) (well mostly not) When I used to repair things with both chips and glass bubbles there was a rule that said - "The more pins it has, the less likely it is to be faulty." Your TEA IC doesn't have that many pins so you could have been right :P
@@NaokisRC If you watch back your video theres a part where you are probing the TEA chip. the only pins on that chip were showing any kind of signal were input. there was a distinct lack of any DC on it. Well done for getting it going :) Now just see how hot that 10R resistor gets as it will be droping more voltage across it than the 1R one.
The people need more old timey "How To with Naoki"
Dude. You just low-key dropped that you created an interface for the board using an LCD monitor and moved on. LOL I want to see THAT tutorial! =)

Really enjoyed that one, well done on finding the bad resistor. Oh, and nice job on rooting out the "old osilloscope informational video" ;)
Finally! A good end to the video
This here is what I used to call the "Laurence of Arabia" fault/issue! (Quite common to CRT TVs too!!!)

I explain in the video that a single burnt out resistor caused the deflection driver IC to not have any power, replacing it fixed the issue.
I found part 2 thank you :)
No problem 😊
@@NaokisRC what was it besides the ohm to turn up the brightness ?

I had read the chip could fail on forums, hence why I looked. I actually tested every single component after abd thats how i found the bad resistor
