Question about Sony KP-53HS20 TV
My television is about 5 years old and is now not working properly. The screen will be fine as soon as you turn it on but as soon as you leave it on for 5 minutes it starts fading into a bluish color and eventually the whole screen is a very bright blue color and you can't see anything. If I turn it off and leave it for a couple seconds and then turn it back on it will be fine for about 5 more minutes and then the same thing will happen again. Any ideas of what is wrong or how to fix this? Do I have to get a new TV? Any help is greatly appreciated. Con't : Is this something I can try to troubleshoot myself? Is it worth trying to get fixed cost wise or should I just buy another one? Amy
Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer
