This is the statistical order of the possible cause of an LCD screen going black:
The backplane lamps, and or the backplane power supply is also failing. Other caused can be from the main power supply, or the LCD panel matrix drivers, or the processor.

When you bring the TV in for service to the factory service rep, they will swap out the boards to zero in on the faulty board.

This type of set is mainly service by board swap, and factory re-alignment procedures when necessary.

I have sharp Lc-32D41u aquos tv. When I turn it on the picture leaves after about 2 seconds, but not the audio. Turn it off & on 4 to 5 times, the picture will stay on.


i had the same problem with this sharp, do not try to repair you are going to waist your money
here is what the problem is : the sound card is bad, you replace it and the same thing is going to happen again and again and again, not even sharp techs know what causes the sound card to go bad. the best solution for this problem is to get a receiver and some speakers and get the sound out of your cable or satellite box.

ps: the sound card is $260.00 and with that kind of money you can get all of this things that i told you
good luck

Sharp Aquos LC-20B6U-S TV NOW HAS NO SOUND OR PICTURE. IT APPEARS TO COME ON BUT WITH NO PICTURE OR SOUND.


This can be caused by many different things. Check power supply fuses. If ok suspect inverter board which drives screen. Check for bulging capacitors and open transformers or just find replacement cost using numbers on board. That may fixya.

Sharp model LC-20B6U-S now has no sound or picture. While watching TV yesterday everthing went out. Screem appears to come on but no picture or sound.


By this description it sounds like you have backlight to the picture which means the power supply in the set is working and the inverter board which powers the screen is working. Your problem may be on the main board if this is the case. I have repaired this set for the same symptom with two different problems. First it could be on the inverter board, and second it could be on the main pcb. Once on this model a piece of metal heatsink slid down due to operating temp. of set and touched bottom of main pcb causing a failure of the sound and picture. Either way, if you have no on-screen-display you will be replacing a circuit board. If you whine loud enough to the mfg. co. they may help you. But good luck.
