42 inch LG Plasma TV - Lost picture but sound still can be heard!
.
the sound is fine on my plasma TV however when i turn it on all I get is a really dark screen and dark shadows.
My 50" Plasma shuts off and won't turn back on at all for many hours, some timnes days! This Exec Call Center number worked like a charm... I, too, just got my warranty extended! Thanks!
I had this problem before on my LG TV. My solution is to put a 12V fan on the tuner board processor. The problem is caused by the TV overheating and when the tuner CPU overheats it sends a high temperature OFF command that instructs the power board to shut the tuner board off (although the rest of the TV stays on). This is why it sounds like a click when it happens. You cannot likely get a TV repair man to fix this because the LG TV's do not have adequate heat control other than vent holes on the bottom and top. This is a design flaw that started a class-action lawsuit against LG.
This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.
Cheers,
Stephen
