I have a 2001 Sony rear projection TV. A few times, the picture and sound goes out- black screen. When I turn it on there are red and blue bands on the screen. After awhile, it goes away.KP-61S75

If the picture is playing fine and you notice that the background is getting more and more red, until it is too red and the set shuts down, it could be that the red screen control is set just a bit too high. If this is the case, you can probably correct this yourself. If you are watching a perfect picture and then it suddenly flashes a very bright red, with thin red lines in the pictureand then shuts down, it usually means that the red picture tube has developed a short in it, between the cathode and heater. A good tech might be able to remove the short by arcing, but if the short persists then the red tube will have to be replaced. Either way, this is something that should only be done by a qualified tech.

Hello......
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.

Rowdyroddy,

Thanks you so much for this info.

I had the same problem with my Sony KW-57wv600. Blue screen turns black after a few seconds, and then standby light flashes seven times.

I called a local TV technician, and described problem. I was told it would not be cost effective to fix. After reviewing the "simple" instructions given on www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html I figured I had nothing to lose.

10 minutes to remove front panel, a "very slight" turn of a screw, and TV worked again perfectly. I could not believe it!

Thank you so much for your help!

SHAME ON SONY FOR NOT POSTING THIS FIX ON THEIR WEBSITE! SHAME ON THE TECHNICIAN AT SONY WHICH INSISTED A SERVICE TECHNICIAN WAS REQUIRED.

I have always been a fan of Sony, swearing by Sony products exclusively. After this experience, I am now forced to consider some other options when purchasing electronics in the future.

Replace the lamp, clean the fans, seen it a hundred times, I know "the lamp light isn`t blinking" replace your lamp and you`ll be back up & running, gl, video-tek

I found this solution from SONY's website.

The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
   
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
   
5. Turn on the television.
