Hi guys, Good morning. This old LCD was working fine all over the year but when I switched on this morning all I can see only front blue LED is flashing. Looks like its stuck on standby. I ESR all the caps and seems ok. Any suggestion please. Regards

Hi Harvey,

Flashing Led on a Vestel usually indicates a main board failure of some kind. Could possibly be a short circuit on DC supplies, but usually it's firmware corruption requiring a replacement board as you can't USB update a board on a set that doesn't go - Chris.
