I have a 2 year old Samsung PN51D530A3FXZA that won't power on. It clicks 5 times and nothing happens. I did a lot of research and based on what I found it seemed the problem was the PSU. I don't have any electronics knowledge, but I'm not afraid to attempt repairs, so I ordered a replacement board and just installed it, and I have the same problem as before. The attached picture indicates the board I replaced.

I waited a couple of minutes, unplugged the connector on the upper left of the PSU and plugged the power back in. The TV played the powering on sounds, but nothing happened...

I had no idea the panels lasted this long. Very good information to know!

Re: Vizio model SV422XVT "VIZIO" logo lights orange but won't turn on

I had a similiar problem and ordered replacement parts (I'm not skilled enough to replace capacitors yet). Was very easy to do, and saved a ton of money. I'm confident that I'll find the right answers here with the issues on my new TV. Good luck!
