Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

RCA d52w20 will not come on

Hi: Recently my tv shut off. I checked the power coming into the unit. The light in the front comes on for 10 seconds then it goes out. It does not flash. I replaced three caps on the flyback board on the advice of one of the folks on here but I still got nothing. I checked for loose or broken solder connections and ribbon connections and I checked the voltage coming from the power supply which is 24vac. Still nothing.
During the 10 seconds there is a sound in front of the tv that sounds like the tubes are warming up but I never get a picture and then the green light goes out.

HELP !!

What is the problem with the set?

Thanks Mike

    How can you test the flyback board to make sure that this board is in fact the problem?



    Thanks

    Is there any way I can double check to make sure it is the flyback before I purchase one?

    Is there anything to check that may narrow down the cause of the set not working?



    Thanks

Sounds likje the flyback those sets are famous for the flybacks needing replacement.They dont always blink 3 times when the flyback fails, often they justrefuse to power up.

    There is no way to test a flyback unless you have a flyback ringer, but thats an exspensive piece of test equipment. The flyback for your model is very inespensive.You may also want to check the tops of the two capacitors CP150 and CP114 to see if the top is domed instead of flat. A domed top indicates the capacitor is defective.

Almost certainly the green picture tube is shorted. This is a very expensive repair; probably not worth doing.
