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're in there which can help with blurriness and focus.

Unfortunately, the Blue CRT will most likely need replacement. But you can get the entire assembly as a complete unit which makes it a easy removal and installation since the CRT is a complete one.

The screen on my Sony wide projection tv is turning blue after a few minutes. can you help? the model # is KP-57WS500


This is a typical bad CRT. The blue CRT part number is 8-733-647-25 but they are no longer available. It is not uncommon for this eventually to happen to the other CRT's as well. The only fix is to have a technician pull the defective CRT and have it sent to a company called VDC for rebuilding.

Tv comes on for a few minutes then goes off


If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each light.red is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.

I had this problem and at the same time I was getting blue tint. When the blue got darker, this would happen, Adjusted the voltage on the guns (3 screws in the front - lower panel off) and the blue went away and it stopped turning off. But later, it would start all over again. Same procedure, same fix.

Red CRT is doing short circuit in the neck. You can try to open the front panel and to hit easy the neck with wood or something and to decrease the red screen a bit. If doesn't work then replace the CRT.
