Question about Pioneer SD-533HD5 53" Rear Projection HDTV
When I try to turn the unit on the stby light turns green then back to red. I can replace the fuse and sometimes it will come back on and work until powered off again. Also In the inside rear center board there is a red light that illuminates when the fuse blows. Left RED LED. Im not sure which board is which when looking at the back of the TV. TV looks great when it works. Any help would be great.
