Hello Madcappers
I hope you can assist with the repair of this TV. I have not been able to find a 'reasonably priced' service manual on line. Can you assist with that?
From what I've been able to assess from this excellent forum, it appears that the A board may have failed but I want to be able to measure the Power board for all its outputs.
Looking forward to your help as the TV is taking-up a lot of space where other stuff needs to be done.
Thanks
Roj.
The problem is 'No Pic, No sound' with 13 blinks after the following sequence. :-

The problem is 'No Pic, No sound' with 13 blinks after the following sequence. :-
- With AC power applied, no red Standby light appears
- When LHS power switch pushed, rapid green flashing light occurs for several seconds and then solid. Two relay click are heard.
- Remote appears to function (rapid green light flashes while any button held, Standby appears to function but no red light, just a restart)
- After 3 mins from ON, the relay(s) click and the 198vdc at the P board dips a few volts and recovers
- After an additional 3 minutes, the relay(s) click again and the 198vdc decays rapidly to close to zero
- This pattern is highly repeatable with any or all of the flex cables detached from the A board
- The pattern is repeatable with either or both power-out connectors removed from the power board (top right and left in pic)
