I have the Samsung 61A750 DLP. I have Direct TV ans recently red pixels starting showing up on my screen and the screen will flash to a pink hue color. I bought a receiver but that didn't help. Upon running through the setup I found red pixels and blurry lines are less visible on 480p. However, when I switch to 1080i the red pixels are pretty bad and the picture is overall crappy. DVD's or blue ray play perfect.
Anyone experience this and may know what is causing it. Or anything I could try. I should mention that during setup Direct TV was telling me on the screen that satellite 103 (a) failed. For some reason it seems not to be picking up this satellite.
