RCA D52W20 - turns on and off, blue screen, tech said need picture tube

I've had my D52W20 for 4 years now. For the past 3 years or so there's been a SLIGHT delaying powering on. I could instantly hear the audio, but the picture would be about 2-3 seconds late. Never really thought much of it. I recently moved out of town, and while i was getting settled the tv was in the garage of my old house for about 4 months over the summer. When I moved it in a Uhaul (250 miles) and got in the new house a few weeks ago it wouldnt work properly. At first the picture was jus a little "blue". Then the whole screen went blue......and had weird zig-zag lines through it.

I waited a few days and tried it again. This time it was cutting on and off by itself. It would stay on for the about 30 seconds, then turn itself off for 3 seconds.....then turn itself back on! After doing that about 4 times.....it simply would not power on again.

I unplugged it and waiting a few more days. This time the tv stayed on for about 5 hours!!! ......but the it powered back off and followed the same routine.

I had a local tv repair place pick it up. They just called and said it 'seems' like it's the picture tube and it's not worth fixing. They said they finally got it power on, but now they cant get it to power off! and said that the picture is of poor quality.

Before I TOTALLY through away a $2k investment.....is there anything else I can do? were they correct? it's a small town, so i dont have much faith in them. Please tell me what you think the problem is and if it's fixable.

THANKS!

It very well could be the Blue CRT shorting out. However the not shutting off is not a symptom of the tube being shorted that sounds more like a signal board issue rather than a picture tube, as the signal board can cause all the symptoms you have described.

    I would say the signal board over the CRT as the signal board can exhibit all the different symptoms where as the tube could only exhibit two which would be a blue screen and shutdown. You can get any part needed at the following link and they also offer free support as they are experts with RCA. Heres the link.

My RCA D52W20 turn on with a blue screen and then turns off within 3 sec's. It goes off like someone has switched off the TV. The light blinks and goes off. Can anyone help


Your blue tube has a short. What you are seeing is the TV turning on and the blue tube going to full brightness. It then draws enough current that the television's protect circuits shut it down.

Need the full model number which should include a BYX or just YX followed by a number. Going off the D52W20BYX1 the blue tube would be part number 263049 which https://www.encompassparts.com still has a few for $220 before shipping.

Rca D52W20 blue screen when turned on


Almost certainly the blue picture tube is bad. This is a huge job to replace and quite expensive. Generally it is not worth doing.

It does sound like the tube, have the shop use a tube restoration machine to rejuvinate the tube, and replace the eprom to try to correct the no power down situation.
