Hmmmm! I would have to say you have a problem with the signal board. I have not repaired this brand or model. This would be the first thing to investigate. It is the board that contains all your antenna and rca jacks. Good Luck and visit your TV tech with this info!

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.

Regards, SD TECH

Screen fades to blue after 10 mins of viewing. Sony kp-57hw40

This link has the instructions on how to fix this problem and other similar problems. You have nothing to lose, so I recommend that you try it.

This works with the two other colors, blue and green also. Not all models of Sony Projection TVs have the red, green, and blue pots in the same order as the picture that is listed on this link, so you may want to google search for your model's service manual. The service manual can also help you be able to remove the cover for your particular model of TV. I was able to find the service manual for my model, and sure enough, the order of the pots are reversed on mine, so I would have been adjusting the wrong color. Read all of the comments on this link too, because you can find other helpful tips and may even find someone with the same model of TV as you that gives more specific instructions for your model.

You may also find your model's service manual here:

I hope this helps you!
Fare well. :)

P.S. you can also clean the mirrors and dry dust while you have it open.

Picture comes on then fades to blue

Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.

Sony KP-51HW40 51 in. Rear Projection turns blue

First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.

you are experiencing one or more of three things
1.the crt itself is damaged
2. the vertical ic on blue crt board is bad
3. the focus block is bad
if you hire a sony authorized technician they should be well aware of this problem.
