Question about Mitsubishi WS-65869 65" Rear Projection Television
Video will black out, but audio will remain. Input or source signal does not matter - it's blacked out on all. After leaving overnight, will work again but will undoubtedly fail and black out again. I'm guessing its the video power supply and have actually changed some of the capacitors already, but not all on the board with the high voltage unit. Will a change of all capacitors work?
Changing all the caps is not the right approach to problem solving.Works cold,but fails after hot is a thermal issue.After set warms up and fails,use cool freeze spray on suspect components to isolate.Determine whether CRT filaments are lit and/or if HV is present.Also,inspect jumper wire from transformer to HV block-if corroded,replace jumper HV lead & HV block w/Mits. parts.
