If your using HDMI Dish has a problem with the HDMI output at this time.
Mine worked for 30 min then quit, I now use component cables. Works fine. John
I have a Mitsubishi WS-65869 connected to a Dish DVR ViP622. Problem is that when I tell the ViP to output 1080i, the TV just gives me flashing blue green and yellow lines, then crashes. 480p works fine and 1080i worked fine with our old dish receiver, the model 6000.
Any way I can fix it?
