Fuse good, standby voltage good? (You can check for standby/other voltage on the CATHODE of various diodes - this is the end with the white band - red on pin near to band, black on chassis.)

Had the exact same issue with a Philips 32" display : https://www.youtube.com/watch?v=p6JM...oed4jq2DPi3ssg

The problem was the flat panel, the ribbon on the left side, from the LCD panel to the T-con had shorted or something and was burnt a bit, cutting the tiny connection. And since these are soldered to the panel, there was no way to repair it without replacing the entire flat panel.

Re: Toshiba 32L502B

ive also noticed today that U5 in the picture attached is getting really hot !

Well, that does look like the main CPU - it's not strange for them to run hot... don't know about during standby though.

Re: Toshiba 32L502B

REALLY hot, though, no that's not normal. On a Vestel, even with their poor thermal design, it shouldn't burn fingers.

I've had bad CPU on a Vestel set before. CPU just got hot, no standby. Was caused by bad regulator, shorting 5V to 3.3V.
