Sony KV-35BRX48 losing Greens
I have an old Sony KV-35XBR48 CRT which I use in my basement mainly for my kids video games. For many years prior to HD, it was my main TV. Got it in '98, and the picture was stunning for SD. It seems the Greens are fading, as when I had a football game on yesterday, the field looked brownish rather than Green. Rest of the picture was sharp and other colors on uniforms etc. looked good. I have a copy of the Service manual with codes, but before I go monkeying around, I was hoping someone could specifically tell me which code or other adjustment could be made.. I'm thinking "Green Drive" but would like to hear from some experts before I have a 200 lb. paper weight.
