It could be a PCB inside, such as L-main, Main, or Y-main, if you open it up and check all the panel voltages you could find the board with the problem by unplugging a board at a time and then seeinfg if the voltages come up, the voltages are on a sticker and the test points and pots to set them are on the power supply board and the DC-DC board.
But the worst possible cause of the problem is, the panel could be shot.
For this problem, I would suggest to contact a pro and have him take care of the problem.

Hi tech101
You seem to have a power supply problem.
I`m going to help you with it but first could you confirm that your tv is a sharp aquos LC-37G4U ?
File is too large to upload here.(5.7megs)
Would need an email address.
did you get that manual?
