I have a Sony KV36FS70 CRT. Recently whilst trying to adjust the geometry through the engineers menu, which I had relative success with, I have committed a cardinal sin: I hit reset whilst in the colour menu which has resulted in an awful colour range that I am told can only be factory adjusted. Im sure there must be a proper engineer out there with the equipment to put the colour settings to blueprint. Can anyone point me in the right direction or advise as to the next step. This was a fantastic TV but Ive muffed it up. HELP!
