No one is ever nosey. Always plz'ed to hear any ones advice. I cannot seem to get into service menu on this set. I think LG from memory locked out the service menu with the newer firmware? This set has the latest 3.75.0 version firmware found on LG's website. I guess I would need to downgrade back to 3.24 to get the service menu back ?

OK managed to downgrade the firmware and enter the service menu. Panel is set right 42 / AUO.

I've had the same problem with my LG, but it's not the same model.
Mine was missing 3.4V from PSU

I did check the supply, will double check it. Thanks.

Update, supply is working to spec  20v  12v  5.2v  5.2v

It's either the panel control board or the Av board. I don't have any spares to swap them out sadly.

dynomo:
Change the AV board this afternoon in this set and all is well again.  :051bye:
