First, ensure your tv is using the highest resolution possible (Usually 1080 for flat screens) by using an HDMI cable from the receiver to the television, and that you are on the correct input. Second, ensure your tv is not sizing the video by using the 'picture size' or 'aspect' or 'ratio' key on the remote that came with your tv (Not your DISH remote). Third, tune your DISH receiver (with your DISH remote) to an HD channel (for VIP model receivers, when you tune the channel to an HD channel, an opaque white 'HD' appears insude the blue box at the top of the screen). Fourth, hit the star key on the remote, while watching the screen. On the right hand side, near the top, it will cycle as you hit repeatedly the star key, the style of screen widening. Hit the key as often as you need to make the screen appear the way you want it to. The receiver will remember your setting for all HD channels. When finished with the HD channel, tune your receiver (with your DISH remote) to a SD channel (any channel in the guide that does not have the HD icon). Repeat the fourth step.

For Hopper/Joey family receivers, hit menu, settings, screen size. Follow the instructions to resize your screen to match your preference. When finished, repeat step four above on each an HD and a SD channel.

Before you do the auto search for the programmes please try to do the factory re set from set up menu. hope your problem will be solved.

The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.

The tv is a 2k model - I have the same one, digital is now 8k so it won't work digitally anymore.

It was a convergence problem, both chips goes bad bad also look for bad resistors around the circuit? This is not an easy repair for non skilled person? You need to realign it after replacing the chips? Don't be cheap pay someone to do it right?
