I've had Dish Network for years and just today had to get a new receiver because my old one was going bad. I used the instructions on the sheet and everything was setting up like it was suppose to. I was on the last step of downloading the memory and all the sudden my tv1 went to a grey static/fuzzy screen. I can't seem to fix it, I've tried unplugging the receiver and restarting it and nothing is fixing it. My tv2 is working fine after installing the new receiver it's just tv1 that isn't so I'm thinking it's not the dish receiver, it's got to be the tv itself. All I'm getting on tv1 is the grey screen with a no signal. I have tried both channels 3 and 4 and it's still not working. I have already called dish and even they don't know what is the problem and I now have to wait a week for a tech to come out. Does anyone have their own ideas of what could be going wrong. HELP!
