I have this Panasonic that is basically stuck in standby mode. Won't power up. I do notice a different type of clicking sound, it's more of a ticking/rattling sound from the clicking relay like it's trying to do the on/off click but there isn't enough power.
Once you plug it in, it does the loud type rattle/ticking sound a few times then pauses for about 15 or so seconds and does it again several times, pause,etc It's never really two clicks like it's on/off cycling.
I noticed the standby is very DIM and if you look closely at it, it seems to flicker non stop but not flash.
I've disconnected the mainboard to see if any backlight would come up but nothing. As long as the mainboard is connected, it makes this clicking sound. If I disconnect it, no clicking sound.

I tested everything that I can think of and believe it to be the power supply causing the fault but wanted to double check before ordering another board. I don't want to make the mistake of mis diagnosing SMPS when it's a mainboard issue.
I've checked out the power supply with what I know and everything seems OK, no damaged caps,etc Only thing I've noticed are two diodes that are 0000 out while all the other diodes are showing .5-.6
Supposedly lightning took this TV out and a few others. I was for sure clicking relating sounds w the clicking relay trying to power on is usually cap related, is this correct?
I don't feel like replacing components on this one, would rather just swap the board but want to make sure it's a SMSP issue before doing so since it's only 30 bucks but mainboard, I cannot find. =/ Thanks in advance
