power supply board is the board where the ac cord plugs in .the . capacitors have numbers printed on board right beside them. there are three to change also check fuse on the board to.
SOURCE: Does anyone know which connector to plug into on power supply
Double check all the connections from the AC line and from the power supply to the other circuit boards. The connectors you are mentioning are identical as per the picture below.
If you need a new power supply, you can find one from this link.
Testimonial: "I have a few more questions that I would love to ask Jaime867. He produced a drawing of my circuit board within minutes and was a big help. Thanks"
SOURCE: Tv wont turn on
Replaced two N-Channel Mosfet transistors(FQPF13N50CF-ND) and some faulty electrolytic caps in the power supply. I found the Mosfets online at Digi-Key. Mosfets are difficult to read. Only one read bad but I replaced both because they are in the same circuit. Set works great now.

If it is a power supply issue go directly to the Manufacturer FSP USA. Get in contact with the RMA department and for about $20 dollars plus shipping one way you can get your PSU fixed. Turn around time is about 3 to 4 weeks so be patient. Once fixed they send you an e-mail with tracking info. I did this an probably saved hundreds of dollars. The removal of the PSU from the TV is pretty straight forward, 4 connectors and just a bunch of screws. Keep track of the screws and where they go also take a pic of how everything was connected to you can reference to put it back together. One warning stay away from a company called Discount Merchant to try and buy a new PSU the sell refurbished junk that does not work. I tried buying from them a replacement PSU that was DOA and they did not want to refund my money and it was a huge hassle and I had to involve the BBB and my CC company to get a refund. Save yourself the nightmare and go through the Manufacturer. Below is the email contact info incase you cannot find the website.
