Broken IBM p202
Hello ive recently put my hands on a beautiful IBM p202 crt and sadly it doesn’t works
Im willing to give it a try restoring it but im gonna need some help,
The tv itself turns on with the light green, after a few seconds it becomes orange telling its going to sleep
When I long press the blue button to do a video test, the tube comes on and it shows a black screen with horizontal lines,so the tube itself isn’t dead.
Also when I long pressed the contrast up button to do a color check, the tube doesn’t even turns on.
Because after reading the documentation and finding out that there are no error codes, I’ve tried plugging a pc to the VGA port on the back, the tv then exit sleep mode and the led turns on telling it detected the computer, but weirdly the tube doesn’t light up at all and it’s only when I shut off the tv that I briefly see my pc desktop video flash on the tube .
I’ve already disassembled the whole tv and I didn’t see any signs of leaking capacitors or damage visually.
I don’t know where the issue is from and I hope someone’s gonna have an idea?
