you won't find any just ,
use a thermal probe or thermal gun as heat is likely the issue ,
if nothing else replace the main diode /rectifier and caps.
I find that if I replace the hottest items that usually the fix
if there is room for a small fan you will be doing them a great service and extend the life of the tv.
you may find some info on the power supply from one of these links they are generic enough

Buy the green light going on means Standby is ok. Next, would be to locate the plug coming from the main board to the power supply and find the post that says PO which means power on. With your meter on that post, press the power button as see if the reading goes High, if it does then the main board is able to turn on the power supply. Next, find the plug on the power supply that goes to the inverter( the long board on the side) remove it and see if you have 24 volts coming out of the power supply when you press the power. If you do, then the inverter board is bad, if you don't have 24 v, then the power supply is bad. There are NO diagrams available for these set other than a flow chart if you can find one. A regular svc tech does'nt need a manual for these anyway.
Let me know how you do Kathy ?

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.
