Hi.

Try first leaving the unit disconnected from power for 15/20 mins, that will probably not fix the problem, but is a necessary step in troubleshooting.

If there is a dim light, that means that the inverter is on. Problem is likely the main control board, but parts must be tested before replacement.

The unit is repaired testing the internal component.

This TV comprises few boards: a Button/IR board, a digital controller board, a PSU, an inverter.

If you are a repairer,testing willl start from PSU, following voltages on main board and testing the inverter.

Parts can be tested following this procedure : A full test ...

the best way to contact an authorized technician is by ringing the number listed on the owners manual. Alternatively try Fixya directory here:Fixya directory- Consumer Products Repair

To get parts try ShopJimmy .

I have sound but no picture on my Sharp Aquos tv.

Do a flashlight test on the screen. With the TV on shine a flashlight on it and look for a dim picture. If you see it, the ballast board for the backlights is bad. If you don't see any movement, the T-Con board is bad. You can get parts from here and fix it yourself. TV Parts Universal TV Stands DLP Chips ShopJimmy
