Hello, my issue is this. I have a three room setup. The 2 first floor rooms have a receiver attached to the TVs. The upstairs bedroom just connects thru a coax cable. Yesterday we had an unfortunate accident and broke the TV in the downstairs bedroom (TV2) I had a older HDTV that I replaced it with, but now I can only get channels to work if I hook up RCA cables. My HDMI cable will not allow me to get a picture. I have tried all means of setup with this TV as well as the receiver. It have tried HDMI 1, HDMI 2, search for channels but no Dish menu. The Modulator on the main TV (TV1) in the living room has the bedroom TV (TV2) set for Cable running channel 75. I have tried AIR and channel 60 just to see if that works but it does not. I just want to be able to get a better picture thru an HDMI setup. Any suggestions? Thanks.
