I have the same problem. TV was JUST out of warranty. Sceptre part number is X37SV-Naga and the cost - $285.00 plus $20 shipping. Non-refundable, no returnable.
The TV is of course going to de-solder the board within a year again, so either a good heat sing on both thermistors is in order OR a law suit against Sceptre is in order for putting us a risk of fire.

I just fixed a neighbor's by replacing the 2200MFD capacitor on the power supply board. Thanks for the help, worked great. If you replace it got for a 16V instead of the 10V and hopefully it won't fail that way again.
Just be careful and take notes when you're digging into it. And mark exactly where the card cage is before taking it loose.

you could try shop jimmys.com or look closely at your supply to see if you might have puffed up caps these can like devices will have a puffed up yop from venting if you find some try replacing them the values are on the side
