SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

If it it new, take it back. The product is not working properly.

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

SOURCE: Sharp LC 46D85U TV with NO SOUND (but perfect picture)

Sound like the TV has a defective audio board. Opening up the TV would most likely void the warranty.
It's best to take the TV back and exchange it for a new one. Personally, I wouldn't want to be stuck with a defective TV ( that just came out of the box ) that they are going to repair for you.

The tv goes off but there is audio.


If you have sound the inverter board has failed,or one of the ccl lamps has died .when you switch on the powersupply sends power but on receiving a fault condition from either of the two faults above will shut down power to the inverter board.

Sharp Aquos LC-32D41U pictures problem


I have had exactly the same problem. Sounds daft but by not using the remote, and only using the power on/off switch on the TV itself, it is working perfectly...no idea why
Use the remore for changing programmes etc but not for on/off
Try it anyway because I know how annoying this is

I had the same problem with the Sharp Acquos LC-32GD8E. A repair man was able to fix this by opening up the back cover and tightening the metal (ground) shield. the screws seem to have come lose. If I had known this I would have done it myself!
