Question about Panasonic TH-42PHD8UK 42 in. Plasma Television
When TV has been on for a while picture becomes very bad with fuzzy horizontal lines. Picture great when TV is cold (only been on couple of hours) but gradually gets worse as it warms up. Problem not with input as bad picture with inbuilt digital tv, sky tv and wii.
SOURCE: No picture or sound
Make sure that there is actualy power going to the AC power source where the TV is plugged in. You can re-set the TV by disconnecting the power for about 10 seconds and then connecting it back again. If the set still does not start it will require service.
If the set is dead it is most likely the main power supply board that failed. The service tech would replace the power supply and also investigate to find the cause of the failure. Sometimes another board could have a failure and cause the power supply to be damaged.
If the set will not start up, it will require shop service. You can call Panasonic tech support to find out the authorised service rep for your area. Check to see if the set is still under warranty. If not, it will be expensive to service.

It can be fixed by replacing the video processing chip. Sometimes together with some capacitors. But the problem is that the rework can not be done easily. It requires special equipment other than soldering iron. Refer ebay item claiming fixing the board. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250579462435&ssPageName=STRK:MESELX:IT
