The fix for this is here somewhere, as I had the same problem last January and the solution was posted here in March last year. I'll try to find it and post the link to it for you, later.

I think its time for sony to face a claas action, they do not supply parts in less than 7 years, and the unit should not have been sold so $high, they should buy them back, that is the best solution

SOURCE: screen turns blue

You may have a bad blue picture tube but there is a way to deal with this first---This is a 2001 model and does not have a light engine---I did one of these with the same problem a week ago---the set has a black plastic block with six controls---three are Focus(red,green,blue) the other 3 controls are Screen controls(red, green, blue) Someone has to remove the entire piece on the front of the set below the screen(usually a plastic part) most of the time it is secured with 3 screws on either side of the set in the back; once you remove the screws the entire piece should pull out(pull from right to left(it will not fall off or come out easy--it is held in with several large plastic pegs) With it removed there is an inspection plate with 4 screws-----the screen/focus block is behind it.

You need to look very closely at the block to identify the focus versus screen controls----one row left to right will be marked Focus and the other row left to right will be marked screen------YOU need to locate the Blue Screen control(they are black like the block) With the set on(be careful) go to a video input with nothing connected---if you see a blue screen as well as the input number turn the BLUE SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE BLUE is gone.

If this cures the problem you may only be buying yourself some time----if the blue picture tube is bad sooner or later this trouble may return----I have seen sets where this was adjusted and the set worked for a year or more with no repeat of the trouble----replacing the blue tube would likely cost you 400 - 500 parts and labor.

I do this here for free so if this has helped you take a moment and give me a vote here.

Could be one of three things the yokes, the flyback transformer or the picture tubes, all will be a costly repair. If it was mine I would invest the money in a new one.

When tv is turned on, in about 10 to 15 seconds the screen goes blue. If the tv is turned off, then turned back on, the picture is fine for about 10 seconds then back to the blue screen.


This is simple--this model is prone to bad picture tubes--blue is most common--screen goes bright blue and set shuts off--set is detecting too much current being drawn--forget replacing the tube--very expensive as only available on rebuild basis.

Here is what to try:
1) you need to remove entire plastic grill under screen--held in one of two ways--either several screws on back on either side or two screws at bottom front under caps.

2) With it free, pull up from bottom and tilt entire grill to the left--the front controls are mounted in it and you will need to undo some ties that hold it to get it out of the way.

3.) Grill has tabs at top that tuck in and you lift it from bottom.

4.) Remove small inspection plate behind grill--a few screws.

5.) Directly behind grill you will find a square black plastic block with 6 shafts (they are controls) One row left to right will be marked Focus--do not touch those. The other row will be marked screens. Look closely (green is the middle one) as each will have r,g,b in small black letters.

6.) In your case LOCATE THE BLUE SCREEN CONTROL. Best way to do this is take set to unused video input and turn blue SCREEN down (usually to the left and less than 1/4 turn) until the blue just goes away---on blank input you should only see VIDEO 1 etc in green.

Do not turn down too much--just enough so blue is not there--no blue background or curved lines.

THIS MAY ONLY BUY SO EXTRA LIFE OUT THE SET AS ALL THESE HAD ALL THREE TUBES HAVE THIS PROBLEM.

You only have seconds if the set is shutting down, Once you get the blue down enough set will stay on.

Take to regular channel and with color all the way off--you should have a black and white screen, adjust just a little if needed.

I have done this many times and most get another year or more out of the set--if one of the tubes is causing this (very likely) sooner or later it may get worse and return to the point where adjusting does not help--when this happens replace the set.

If this has told you something that helps you or you did not know rate this solution as very helpful as I do this here for free.

If you have questions let me know BEFORE you attempt it.

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.
