When I turn on the TV it powers on for a few seconds then once it is inished loading it has a static sound then turns off completely. The picture goes dark, and I have to turn the set on again.

Micah Moore let us know if it truly turns off or if the screen just turns dark. You will also have to let us know if it immediately turns back on once you reset it. This could be a power board issue (as well as a main board issue). You will have to measure the voltage on your LED connector and check what your power board puts out. Let us know what you find.
