How to test power supply board on lcd tv I checked the fuse with multimeter and it's fine. When you turn the tv on you can hear the clicking but no led indicator lights on. I try to system reset and you hear multiple clicking, still no Led indicator. It seems like it is the power supply board. Is there a way to check if that is the problem before ordering a new board.

Hi! that is the typical problem of damaged electrolytic capacitor, check that they are not inflated at top compare with other ones on the board if so replace it by new ones careful to put them back be sure they have the same capacity and voltage and also they have position + and - on the board respect their position. Take a look at this video.
