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.
Thanks!

FIXED!
The mainboard was the issue. I swapped out the mainboard and TV works great!
Thanks again for everyone’s help!

Hi,
I think you would need to FIRST swap out the power supply board.
If that doesn't help, then the motherboard.
I had to change BOTH of those boards to get my TV working
