Tv keeps turning itself off and the white in the picture looks alittle off.

To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

Do you have its schematics or service manual? This kind of problem needs detailed schematic diagrams of related product. Let me know, are you Tech-Person or TV-Repairman?

Picture goes on and on constantly

I have the same problem. Picture cuts out completely then back on. When I first turn it on, it does this constantly for about 15-20 mins, then about once every 30 mins or so. The sound is fine, but the picture just flashes on and off.

The color is also starting to shift a lot and cannot be fixed by adjusting COLOR-BRIGHTNESS-PICTURE in the video control menu system. Nothing seems to correct this. I've even unplugged the TV over night to see if it needed some sort of reset. Model = KV-20FV12. Purchased in 2004

My connection is a direct cable connection - Comcast cable. Same problem persist while showing a DVD as well.

Sony 27"TV will not turn on

The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.
