Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Most likely you will need to replace the main board. That model # uses several different main boards. The part # will be listed on the board. Make sure you order the exact part # of your old board.

If fuse is dead, there must be some reason for that. Some short circuit or so. Without rectifying the fault, if you replace it with an other fuse, the fuse you insert will also blow out, and might make more faults to occur. The rating of fuse will be marked on the printed circuit board itself, very near to the fuse.

Most plasma TV's have secoundary power boards, witch can be the cause, now I would try if I where you is to unplug it and let it set a hour or two, if that did not work then the tv will need to be looked at locally. The cause can be a bad power board inside the TV witch is a major cause why a Tv would have a power light put no function at all.

Hope this helps if you have any questions as to what parts to buy www.partstore.com is a best resource.
