Samsung LN46A550P3F C LCD clicking

[Browns329]

Samsung 46" LCD TV
Model: LN46A550P3F C
Model Code: LN46A550P3FXZA

TV off. Standby light flashing and relay on power supply board clicking every few seconds. Press power button and no change.

Unplugged main board from power supply board and clicking stopped. Plugged main board into power supply board but unplugged everything else on main board - still clicking.

Does this indicate a bad main board?

I don't see any visual signs of bad caps, burns, or cracked solder joints on power or main board.

Thanks for any tips.

"A" model years have bad caps (make sure they aren't bulged on the tops) and also a bad C102 cap on the main boards. https://www.badcaps.net/forum/showthread.php?t=45913

indicates that you must begin from the power board, must check it forcing its main stage on.
