(1/1)

JAYROD:
Tv stuck in standby,red led,no clicking relays.Power supply can be turned on if i pull the control line low (standby active high) and all voltages seem to be present and correct. No faulty electrolytics on board.
No service manual. Any ideas ?, eeprom corrupt perhaps ?

Any help appreciated phil.

GGTVBD:
Did you ever get to the bottom of this Phil?

I've got the 42" version with exactly the same fault.

Cheers.
