Sony Trinitron KV32FS16==> Need to push pwr button multiple times

Hi, I have a Sony Trinitron KV32FS16==> Need to push pwr button multiple times. The flyback transformer will buzz, and shut off, so I replaced the flyback. When I push the power button now, I get the same result. It will buzz, then shut off. I need to push the pwr button multiple times and eventually it will turn on.... Any thoughts on the issue? I heard maybe the horizontal output would need to be replaced....But not sure...

After it fails how many times does the red LED blink? check the board very closely for any cracked solder. and then check the main regulators. also look to see if you have any physically bad capacitors, they might look like they are exploding on the top.

you have a defective horizontal output or the flyback is bad.
horizontal output is a big transitor on a heatsink near the flyback. the flyback is the coil that feeds energie to the bulb with a thick red cable.
be careful to discarge the bulb before removing the flyback.

Tv won't power on


the flashes are a indication of the actual problem. 5 flashes along with a popping sound is the flyback transformer failing to provide the high voltage necessary to reproduce the image on the screen.

Timer button blinks but doesn't turn on


There are several faults that can cause this. Shorted diodes in the high voltage, a bad flyback transformer, a shorted CRT driver IC. None of them are very easy to fix.
