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

1 Answer

RCA 55" HDTV

TV on and while watching "signal no found" appeared then a loud bang (sounded like a shot gun) sounded and the TV went out.  Turning the TV on, the light flashes and makes a buzzing sound.  Anyone have any idea what may have blown in this 2-3 years young TV?

Sometimes a part can go shorted, and an over voltage occures somewheres thus causing another part to blow. This can be anywhere from in the power supply to any of the other boards.

The set would have to be serviced to determine the cause and what was damaged. Most likely there will be the need to change some boards. Most of the service is done by a combination of board replacement and some component replacement depending on the exact type of fault.

No picture but have sound


That click might have originated in 2 places: either it was the main relay disconnecting or it was the sound of a capacitor popping. Both are very severe problems - they signal that the power source of your tv has just failed.
Fixing it is a job for someone with electronics experience, if you're not one then call a repairman.

Sounds like either something went pop on the main pcb or in the power supply. Will need a repairman to take a look. & Just a caution if you're feeling adventurous, don't do it yourself unless you know what you're doing!!

someone shot your tv.





no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..

there should be 3 sets of video rca jacks on tv or receiver they might have put them on the wrong rca jack in which they just need to be moved over
usually the 3rd set of rca jacks are component jacks not for tv or video but for low output signals say like cameras and only one set of rca's can be used at a time svg on one of them rca's will over power the vid's. so have no picture

Tv wont turn on


The loud pop was a capacitor blowing up or the high voltage transformer blew up. Very common problem.. if its the Transformer be expected to pay 250 or more to have repaired.
