Sharp aquos 32" LCD tv - screen black (no picture) but have sound

Bought this tv 3 years ago and the screen has periodically gone black even though the backlight is on. This has got worse now that it does not come on at all!!!! However oddly, it is fine when it is on EXT5 but not EXT1. The sound works when the picture disappears. Have checked all the plugs are in and they are fine.

Is it something inside the tv which has lost its connection? I have tried a factory reset which worked for two weeks but it is back to what it was before. Don't think there is any warranty on this and don't particularly want to spend hard earned cash on a new one that should still be working afer 3 years!

Can someone help?

Typically if you have a backlight and no video image it's going to be the T-Con board. We do know it's most likely not the powersupply board because the back light comes on. Could also possibly be the main board, but typically the T-con boards are cheaper and I'd say you got a 70% chance that's the issue. Good luck.

My Sharpe Aquos TV screen stays black even when switched on!


Call up Sharp, if you are part of the AQUOS Advantage Program, you get FREE in home service along with the repairs for it.

They'll give you a case number, set you up with a technician and BAM!
I called on a Wednesday and got an appt for that Saturday for the technician to come to my house.

Sounds like one of three things:

1) Mainboard/Tuner problems - although I'm really only saying this because you guys seem to think its associated with your over the air channels.
<br>
2) Power board problems. You power board/inverter may be damaged in some way - blown capacitor or other malfunctions. This is very possible as this could result in the backlight turning off and the screen going black but keeping the keeping the sound. If this is the problem, it will at some time start to happen constantly. Have a pro open it up and look at the power board.

3) The backlight is defective/dying. The backlight is a set of lights that reflects through the LCD panel. If the screen looks black, but you might see a faint picture or you still hear sound, then the backlight is not on. The panel itself could be defective. You can fix it by replacing the whole LCD panel (expensive), replacing the backlight panel itself (need a busted LCD of the same size with a working backlight), or fix the backlight, which is tough and risky.

Most likely its either the power board or backlight. Either way, you need someone to open up the TV and take a look inside. Good luck! Hope it works out.
