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.

SOURCE: Magnavox 30MF200V/17 No picture, only sound

Do you know if i can use an inverter from any LCD tv, or does it have to be specific to that model? I was thinking about taking an inverter from another broken TV.

SOURCE: samsung 42' plasma tv,screen keep flashing, blurry,no pics

I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.

SOURCE: Sound stays on, but no picture- goes black and stays that way.

This unit should still be under warranty and should be taken in for warranty service. Any attempt to access the interior will void the warranty. It is important that a complete description of the problem like you entered here be taken along when you bring the set in for service. This will insure that the servicer be able to reproduce the problem and resolve it.

From your description (and as a servicer), I would be looking for a component that is heat sensitive. These types of problems are fairly easy to locate and resolve.

Please take this in for warranty service and update this when you find out the details.

Thanks,
Dan

SOURCE: HAVE SOUND BUT PICTURE GOES AWAY 32INCH 2 YEARS

Check for cold solder joints in the power supply board around the 24vdc section.

The problem can also be in the backlight inverter board also, but you need to find out if the power supply is putting out the 24vdc first.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

The cost of getting this plasma fixed is not costwise compared to getting a new TV. I recommend NOT to get another plasma but get either an LCD or LED for the best quality compared with price. Plasma parts can be quite expensive especially for a 10 year old model or may not be available.
