    I have exactly the same problem with the same model. It started the other day, and appears to be getting worse. If you switch it off and on again a few times, eventually it gets a picture. I've read a couple of posts which seem to suggest one of the boards inside which controls the back lighting, but if possible I'd rather fix it myself than spend a fortune getting someone in.



    We've had the set for about 18 months. We already had a big argument with Curry's when the power supply blew up after 4 months and the refused to repair it. Finally ended up taking it down to the store and dumping it on the managers desk until he agreed to fix it! It's now out of warranty though, so I fear a costly fix coming on. Any help would be very very gratefully received.

    I've exactly the same problem unfortunately this is the 2nd problem that has developed with this tv and it's now out of the warranty period. I repeatedly have to switch the tv on and off until the picture stays on the screen but the problem is getting worse. No one in my area will carry out the repair and I can see myself forking out for another tv.

    I have the same problem with a just of of warranty unit and have noticed that if I hold down the on/off button at the top of the unit, the picture will appear and everything works fine, until I let go of the button and then the unit switches off.

    Does everyone else with this problem, find that holding the button down does allow the unit to work. If so this shows that the power supply is OK and the unit functions... if you keep the button held down

Okay. Here's my best stab at it. I've repaired several of these and it has been one of two things. First and most common is the inverter board. That is the board with a metal shield on it and a row of small transformers. Problems on these boards consist of open pico fuses due to leaky filter capacitors (usually 220uf is the value), or a transformer opens on this board. You can attempt to repair it or google the number on the board for a replacement unit. Second is underneath the main board sometimes a heatsink will slide down because it wasn't securely anchored and short or arc against main p.c.b.(solder side). To access this you must remove the two large side-by-side boards from their mounting brackets just to get to the board below that you want to look at the bottom of. This is a major disassembly, but it can be done fairly easily with limited distractions. When you remove the bottom board and all the plug connectors you will see a goopy, putty looking compound that was meant to hold the heatsink in place,and you will see a burn mark and open fuse or resistor if this is the cause of your trouble. By this you should know that I've spent my share of time researching this problem so as to help you and others like you. Good luck, Russmann.

Check the audio 'output select' under the Systems Settings menus. The output may be set to 'variable'. Set it to 'fixed' so that the audio runs through the speakers.

Sounds like the Main mother board is the problem. When the processor chip overheats, the programming information passing through the chip slows down. Most cases, replacing the main mother board will fix the problem.

You must use the video and audio with their own separate cables. The sound is separate.
If you are following proper procedure, then you should contact the tech support for your set to find out if there is a defect somewhere.

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!

This is most likely has a bad main bd. No discreet component repair with unit. I can't give any information on the boards because this is not a good model # according to my Sharp site.
