Question about Sony KP-61S65 61" Rear Projection Television

Sony 51" projection fading to red

When I turn my tv on the color is perfectly fine then in about 45 sec it starts to fade towards red, so my once blue guide menu is now more of a magenta color. Is there an easy fix for this or am I better off calling someone to come out.

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.

Normal pictures fades to blue screen within 30 seconds

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.

KP-51HW40 Sony 51" Fades to blue screen

The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

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.
