Panasonic 42PV80b

(1/1)

Any known faults with Pan. 42PV80 plasma other than exchange board. Powers on, no display, loud, rough buzzing sound from Sus Board TNPA 4394. Expected supply voltages at the board.

Hi,
What is happening to the front LED?
Is it blinking?
If yes how many blinks?
If it isnt blinking , is it solid red or solid green?
It may be in protection

Thanks for your reply,

The led blinks very rapidly for about 5 secs at switch on, blinks a few times, then settles to solid green.
The buzzing as the relays kick in.
Any other comments would be helpfull.

Regards
Theo Laird
