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

1 Answer

I have a D52W20 RCA tv. The picture will go out intermittently, but the sound is still on. When the picture goes out, sometimes you can see it faintly for a few seconds before it fades completely

    Thank you, found a loose solder at #3 of a component I believe is called the oscillator.

Possible errors in the main board , it can be due to failure of a solder joint in the set.
Remove the back panel and switch on the TV to work. when the fault appears then the main board can be tapped lightly to see if there is any switch on of the picture. If so the fault is confirmed and you must resolder the dry joints of the suspected areas.

Look carefully with a good lighting to check the joints specially the high voltage and the power circuits.

Tv pops on and off suddenly after viewing for about 10 to 15 mins. this problem becomes progressively worst after prolonged viewing. as of today there is absolutely no picture and or sound.


Your symptoms exactly match this scenario: a component involved in picture & sound was failing intermittently, then progressed to a hard failure.

My suspect: a power capacitor in the power supply. They sometimes fail this way - when the dielectric breaks down completely, then the power supply fails, causing no pic/sound.

Fix: replace power supply (or the specific capacitor, if you can determine which one died).

I have a 52 in RCA Plasma TV and when I turn it on nothing comes on but just sometimes a green blank screen with no sound and sometimes power goes on and off. Ive hired an technician to look at it last...


The RCA D52W20 has three picture tubes the problem you describe is symptomatic of a shorted or a bad green tube. other problems could be bad crt boards. high voltage block, In the case of tube replacement i often suggest the cost of replacement is more than the set is worth. so i would suggest getting a second technicains opinion

My rca 52 inch hdtv turns itself off after a few minutes


Sounds like the green tube shorting intermittantly. Have a qualified tech use a tube restorer to check for shorts, or the loss of the 300v line to the green tube.

42" RCA Projection TV - Sound good, but Picture goes out intermittently.


resolder the vertical output IC . bad solder there can make the CRTs blank for protection and you will lose the picture when the vertical drops out.
