Re: Samsung PN50A550S1F does not turn on, relay clicks.

I have the same TV Set doing the relay clicking and the standby light in front of the TV going on and off as t clicks and not turning on. This happened after we lost power at the house and left the house. When I got back power was back and TV was down with this. I followed advise on some forums and did not find any bulging caps on PS but I replaced them just in case. When I unplug Main input Board the clicking stops and I installed two parts from the shopjimmy.com main input board repair kit (except for the IC on top/sound)...

Re: Samsung PN50A550S1F does not turn on, relay clicks.

I have the exact same problem, replaced some caps on the PS and purchased a main input board repair kit and replaced an ic and another part on the bottom of the board but no luck there. Reason for the kit on main board is that I isolated the relay clicking to only when I plug the main input board. Have you found a solution to this? Heeeeeelp.....
