Re: LG 50PQ6000 unstable 5v standby
ok.
I cant test the PSU board in the TV at the moment since I have had to put it the TV back on the wall while people visit.
I have had a little time with the board stand alone.
When I plug it in the relays make a sound like a galloping horse. Even after I remove the AC the relays keep clicking for about 40 seconds as the capasitors discharge.
F302 is 328VDC
Across the large capasitors is a stable 320V
By my calculations these are Low they should be 382V
stand by 5v is a very unstable 3-4.5VDC
