Problems with my MITS 42"HDTV

[hrtbeat2]

Ok, First I hate this T.V! But it's my own fault for not doing my homework , Anyway my T.V is a Mits 42" HDTV Rear projection. I have to line up the bulbs about every month or so with the color correction (red/blue) grid. The problem I'm having now is on the right side of the T.V it has a red line starting to show and on the left it's blue? I have gone in and adjusted the red/blue setting and they show it is fine but it won't go away

What mode and cables are you using.

I'm running DVI cable to my T.V, and from the cable box comp. cables. It just started doing it??

Edit
Just started doing it after the new termination with DVI?
on both inputs?

No I've had this S/U for about 3years now. DVI from DVD player to DVI input on T.V. From wall outlet is standard cable to surge box, the cable to the back on the cable box. Then the component cables to the other inputs on my T.V. I hope this helps?
