Question about Mitsubishi VS-50603 50" Rear Projection Television
My mitsu vs-50603 manufactured in 12/98 will not power on. the green light on the front panel is on all of the time. nothing happens when power is pushed on set or remote-----no sound or noise from the set at all.
Good Day, Check these two areas: 1. CHECK IC700 PIN 4 (AC-OFF) FOR 0 VOLTS DC, IF HIGH, CHECK FOR LEAKY D980 PART # 264P045040 ON THE MAIN PCB. 2. CHECK FOR 4.7 VOLTS DC AT CONNECTOR RF PIN 3 AND 4 ON THE SIGNAL PCB IF LOW SUSPECT PROBLEMS WITH THE SWITCHES/BUTTONS ON THE CONTROL PCB PART # 935D394001. 2). CHECK FOR 10 VDC AT PIN 5 OF IC502 OF LOW, CHECK IC503 PART # 270P704010 ON THE MAIN PCB. 2. CHECK R529 .82 OHM 1/2 WATT OFF PIN 4 OF THE FLYBACK. IF OPEN CHECK C411 2200 UFD @ 35V AND IC 451 PART # 270P064020. ON THE MAIN PCB. Good Luck, big IRISH.
