Question about Toshiba 57H81 57" Rear Projection Television
It appears that problem is power supply related. No high voltage, no audio. Set does not power up. Fuse not blown in low voltage circuit. Need service manual to trouble shoot. Any recommendations where to get schematic. The places I see don't inspire confidence. PDF downloads etc. There is a relay in low voltage circuit which I can here energize but then LED flashes but set doesn't appear to power up. Any help appreciated. C5Z06
I had this problem and found pico fuse (5A 125V) F850 open. I replaced it and the set powered up with a perfect picture. F850 and F851 power the convergence circuit. You will have to solder the replacement fuse in place.
