Help i have this set which when powered on shuts its self back to standby after about 5 seconds when switched on. Any ideas? Checked the psu outputs and all good if but briefly!
Inverter Power board MPF3934
Main board pe0492 v28a000670a1
psu PE0490A V28A000671A1
Suspect inverter board but schematic seems to evade me!
Thanks
Happy Christmas and have a great New Year :)

Good News Bought the remote control for the TV and used it to switch it on!
Now its fully functional!
Work that out

It turns out the Panel Lock feature had been enabled thus disabling the front buttons operation!

I would change the caps on the inverter just for peace of mind as they cause loads of probs.
