A recent lightning storm took out a LG 50PJ350 TV (and a Cisco DPC3939 router), on to the LG 50PJ350:
No picture but sound is working (through atsc coax input)
Shorting 'Auto Gen' (LVDS and Main board cable disconnected) produces visible test pattern
Control board LED on when only 5V Standby connected
Main board suspected, surge possibly went through an hdmi input
More to test and I'll update the thread when I do.
I'd like to repair the components on the board then just swapping it. I haven't seen any visible signs of damage. Anyone successfully repair a main board like this? I'll be testing with a (hopefully) working main board just to be sure. So I should have a reference.
Pictures and 'Training' Service Manual to be added on request.
