You will need to try a few more things before anyone is able to assist you.

Do you have sound? If so, take a strong light and shine it on the screen and look to see if you can see any indication of picture. This will indicate a back light issue.

If no sound, Sharp's normally will indicate the fault by having the power light flash. After initial power up, the power light may flash a combination of short and long flashes to give you an idea as to where the problem my lie.

It's hard to say exactly where your problem is unless you have some electronics background or the schematics. Start by checking your power supply output. Since the set seems to turn on, your standby +5V should be okay but check anyways. You should also see +12 and +24. Depending on what you find out here will determine what to check next.

More than likley the digital main board. It's not flashing a 1-1 which means panel, you have no sound, the green light is solid not indicating a fault, suspect the main.
