Hi All, I have an LG 50PK550 with the EAX61392501/10 EAY60968801 power supply board. When I turn it on it clicks and shuts off immediately, I have unpluged the power wires to to Zsus and Ysus board and it does the same thing. I have read up and replaced IC301 & d304 and checked the R927 R929 and all 3 fuses on the board and all appear ok. Still does the same, shuts off immediately with or without the z & ysus board hooked up. Any help would be appreciated. Thx

Check for cold solder on the underside of the board, pretty common. -

Have a look at the components in this repair kit and check the parts on your power supply.

Check all new parts and they match old, also checked with meter and all are good. Thx

This is a weird one, as mentioned below I checked and replaced the below components and put the the board back in and it did the exact same thing. As suggested I removed the board, reinspected and checked the complete board for cold solder joints and none were found. The board was a little dusty (I have seen much much worse) so I gave it a good dusting with a paint and tooth brush and put the board back in. Now the TV stays on now without issues, I have given it two tests for over 8 hours each. Is it possible there was some dust shorting out something on the board ??
