RCA Model No. 42LA45RQ
Power Supply Board No. RE46DZ2004-20110917
No picture, red LED only when powered.
I have search/read treads relating to this model # and replaced recommended blue high voltage caps near the output from the PSU to the inverter (4 total). No fix.
I did find another high voltage cap that is bigger/expanded than the same value cap next to it. Could this cap be causing my problem(630V471K)? I've included a picture showing its location on the PSU board.
630V471K ---> is the cap value for this ---> 470pf 630V?
History, This TV has been sitting in my basement for the past 6 months waiting for my attempt to repair. I replaced the 4 mentioned caps above about a month ago with no luck. Today I decided to give it another go. I checked for cold solder joints and touched up anything that looked odd (did not find any visible problems). I then removed the PSU board again to recheck. Again found no cold solder joints. When I plugged everything back in, the TV powered up with no problems (red LED now blue with great picture). I was very happy at this point. Unfortunately this was short lived. The TV will not power on as before. I get no back light, not even for a split sec as before. Only the red LED comes on when the power plug is plugged into AC outlet.
Any suggestions?
