If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.

SOURCE: have a 30" SHARP Aquos LC30HV2U that has a bad power supply. Nothing happens when I turn on the LCD - though it is getting power confirmed by green light going on but nothing on LCD. Visual inspection
You did try the CLEAR button on front of the box?
One possible idea is the cables going the box to the TV. ( might be bad )

It appears like the 5VDC is low from the power supply adapter. This voltage becomes low due to defective capacitors inside the power supply.
