Dish Network not showing picture on TV1?

[Joe]

My current stereo amp crapped out so I am trying to bypass everything in order to keep watching Dish until I resolve that problem.

I have a Dish 625 receiver. I have run a brand new coax from TV1 out (ch3-4) directly to my TV. No signal/sound at all. Yes, I have run auto channel program and manually tried all channels suggested.

Now if I disconnect the TV2 coax and plug my new cord into that I get picture/sound just fine. Just not when it is plugged into TV1 out. Up until now I used the S-video so I have never actually tried to use coax for TV1.

Is it possible that connector coming out of the receiver is crap or am I just missing the obvious? Thanks for the help!
