HI, I am new to the board and need a little help. I have a mitsu WT-46809 Widescreen TV. I recently had HD cable installed. I am noticing a lot of red in black backgrounds. My side bars when viewing 4:3 signals have a lot of red in them. I was thinking it was the "red push" problem, but when I disconnect the red cable the red is still there in the black. It does go away when I un-plug the green cable. I tried a 3db att. on the green cable and it will not syc. I tried a 1db att. and I didn't notice a difference. I am out of ideas and would like some help. Anyone have any clue what is going on with my TV. I have switch cable boxes and with the same results. Also I am only getting this kind of picture on this input. All others are nice and black.
