Unfortunately without being able to inspect the unit, I'm unable to give a diagnosis. A technician would be able to give a fix cost, but I don't have any way of providing an estimate.
But I'll be happy to bump this back up to the top of the thread in case anyone else has had a similar experience.
I have a Plasma Samsung SP-R4212 , Serial # ACET3CFY800633T , assembled in August 2005. I had a plug in my garage short out last night and i lost my computer and TV . They worked fine before that. My TV was hooked to the PC by VGA in my rec room and PC VGA was also splitted to a monitor in my garage , so garage monitor was on a different circit.......PC was surge protected but tv was not but still lost PC i think , when i turn it on now there's only a yellow light and the fan is spinning at hight speed so i 'am thinking i lost the power pack. But my main concern is my TV , when i plug it in the remote sensor light comes on but nothing else , no picture no sound . I checked 4 fuses in back of TV and all rang out on my meter so they seemed fine. So now i don't know what to do with it all........any idea what the problem may be , any idea what it may cost to fix .
