Question about Sharp Aquos LC-46D62U 46 in. LCD HDTV
Hi. I have a sharp aquos 46d62u, and recently, when turned on, the sound works, but there is no picture. This problem affects all inputs. The first time it happened, we left the TV off and unplugged all day, and it still wouldn't work until after that we tryed pulling the HDMI's out and re-plugging them, and the problem seemed fixed. This time, however, unplugging and replugging isn't working. The audio is just fine, but there's no picture what-so-ever. Maybe someone knows what's wrong and how to fix it?
We have the same problem with our 32" Aquos. Turn on the TV and after a couple seconds the picture goes out but still have audio. So this solution doesn't permanently fix the problem, but it works instantly to get the picture back. With the TV turned off, tap the side of the set twice with the palm of your hand. Turn the TV back on, and VOILA, you have a picture. I know the last thing you think to do is to hit your TV to fix it, but that is often how my husband tries to fix things...this time it worked!!

Hello to all who have posted Aquos TV sound but no picture. I had the same prob and for weeks found different ways to get it to work but, finally all solutions failed and it was a trip to sharp (reason I had not done it previously was TV bought in Germany and now live in Italy but warranty honoured). I believe from the amount of Aquos TVs in the repair shop and the fact that the guy said come back in 2 days he knew exactly what the fault was and therefore think sharp should be recalling all the TVs to sort the problem out! I am sorry for the people whose warranties have ran out. My TV started playing up after only 14 months.

Use component cables (red,green, blue) for picture instead of HDMI. Then also use a form of audio cable also, as the component cables will pass HD picture but no sound.

I can't find the gentlemens name that posted this already but I can tell you that his solution was correct. I did mine just a little differently.
1. First take all the screws holding the entire back panel out with a small Phillips screwdriver.
2. Remove the entire cover.
3. The board that is directly behind the hdmi inputs has five screws in it. Loosen them all but don't remove them and push the metal trim that's around the board away from the board to where there is a small bit of separation from the metal trim and the board and retighten the screws.
4. Double check that it has a gap on all sides and replace the back cover of the tv. It is a very easy process and not at all as intimidating as it seems.

I HAVE THE SOLUTION!!!! My 52" was doing the same thing. It would work and then picture will go to snow and no inputs worked, the remote didn't even work! I would have to power everything down (Reciever, PS3, etc.) then it would work but no telling how long. Even touching the TV where the buttons are made it go to snow!! THIS IS WHAT YOU DO. Take the back cover off. Where the side buttons are, there is a board in there and it is touching the metal frame. Take something like a credit card and cut it enough so that it will not be sticking out, get some electrical tape and anchor the card to the metal frame so it will not fall out of place. You're basically protecting the board from touching the frame!! Put the back side back on and screw in place and your all set. My TV has been working perfectly ever since.

I had the same issue...great picture but NO sound. I unplugged the TV for 10 minutes, plugged it back in, and shazam! sound again!
Is this an ongoing issue with the Sharp LCD?
