Question about Sony KP-57HW40 57" Rear Projection Television

2 Answers

Blue screen When we turn the tv on we have a clear picture but within 5 seconds it turns blue and stays blue for over an hour or so. Then the picture comes back, but still has a shade of blue to it. The tv is only 3 years old. Any suggestions before I call a repair service? Thank you!

Full Color fading to blue then screen turns off. Repairable?

Here is what you need to do.

1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.

2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)

3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.

4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.

5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)

6.)Usually the blue will be on the bottom left--it does vary

7.) Once you locate the BLUE screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Blue Screen control.

8.) Best way to do this if the set is on is on a video input with nothing connected--you turn the blue down until the set stays on and then very slowly turn it up until you see a slightly blue screen with or without diagonal trace lines----if you get it to turn on this way turn the blue screen back down slowly until the blue screen and trace lines just disappear.

Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the blue screen down a few times to get it to stay on.

I do this here for free and if this helps you at all give me a vote here--it costs you nothing.

TV turned off itself

Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?

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

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.

My HD50LPW62AYX2 RCA TV sometimes reverses the blue and reds. The peoples faces are blue, especially the lips.
Sometimes turning the TV off and then back on again fixes the problem. At other times this correction is good for only a second or two.
Do you have an English owner's manual available on line or otherwise available?
