I have a Samsung TX-R3079WH 1 day old. I hooked it up last night with poor channel quality and extreme colour "wackiness". I have RCN digital cable with a Motorola box. I live in a 15 unit building. I also have a PS2 that confirmed the colour "wackiness" which is bright and disturbing. My 10 year old 19" has a better picture! Can someone help with some advise? Should I return this set? Do I need a cable booster?
