Question about Sharp LC-52D43U 52 in. LCD HDTV
My 52" SHARP LCD TV gets a snowy image after it is on for around 10 minutes. If I switch the input from TV to DVD then to computer I get the same effect so I think it is not the cable. I am thinking it is a cold solder joint on a part inside the TV but witch one? When I first got the TV the snow would show up but then it went away. For 4 months the TV was fine but now the snow is back. When I tap the back a little the snow will flicker. Any ideas what part this might be? I am also looking for a service manual so I can fix the problem myself.
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.

These sets are notorious for bad inverter boards and bad video processor boards.Sharp is well aware of the problem,and will fix the units if you push the issue.They have fixed these ynits out of warranty with a smile.This is a issue with defective parts not connections
