It can be the bad power supply, bad backlight inverter board, bad main board, you will have to start looking at the power supply module first to make sure it has all the voltages the TV needs to work.

SOURCE: Sharp aquos lcd screen goes blank

The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem
