Question about Sony KP-43HT20 43" Rear Projection HDTV-Ready Television
The screen has a more green colour because the red colour keeps coming and going. I tried using different inputs on the t.v and using different DVD players and RCA cables and it still doesn't help. Can anyone help me narrow down the problem. I don't know if it's worth fixing or just buy a new tv.
Not absolutly sure but it sounds like one of the crt's are starting to fail. Sony has a white balance circuit that constantly will attempt to correct for white balance errors, if it has a hard time fixing the white balalnce what you describe can happen. Durring these events your tv's power button can blink in repeating pattern of 5 blinks indicating an akb or auto white balance error. Eventually the picture may flicker on and off or the tv will shut down all togeter with a 5 blink error. But i cannot be sure without looking at it myself. There are other causes aswell; focus block, or a crt driver can cause simular issues. But given the age of this set i feel it is a better chance one of the crt;s are going bad. But again it could be the other things i mentioned.

You have already done all of the trouble shooting. The t.v. will need to be serviced, and the time and cost of having the tv repaired is not worth it in my opinion. Most repairs such as this will take a service center 3 months to diagnose, order parts, get parts, and install parts. Even then the issue may return. New LCD's have dropped greatly in price and is what I recommend.
