I have had a 27" Sony Trinitron TV (KV27S45) for about 2.5 years and only recently, I have noticed small "wavy" lines over the entire screen when I am using the S-video input. When I remove the S-video input, in favor of the RCA input, the lines dissappear (with the obvious loss in picture quality). I have tried 2 different inputs (DSS and DVD) with no difference, as well as three different S-video cables. For some reason, depending upon the physical position of the cable, the definition of these "lines" seems to dimminish, but never quite goes away. While I know I can use the RCA video input ...... Any experience/suggestions? By the way, for some unknown reason, when I bought the TV, I decided to purchase the 4yr protection plan, WHICH I NEVER DO. Just my luck, huh? The one time I do buy the protection plan, the item breaks. Thanks.
