No Power / No Standby Light (already tried PS Board) LG 47LA6200
Can someone suggest what to try next?
TV is an LG 47LA6200-UA.
Symptoms are: NO power at all. Not even the red LED standby light.
I already tried TWO replacement power supply boards and Nothing.
Still, no power at all and not even the red LED standby light. (See photos).
(I also tried a new power cord just in case - but nothing)
***What should I try next?***
Is it possible that the mainboard is the issue?
NOTE: I can probably dis-assemble and replace parts, but I’m NOT a technician and I don’t have sophisticated test equipment.
Esta é uma boa pergunta?
