Got this problem solved today by having a tech come out. Turns out the boxes they were giving me at the local service center don't work on there system. Basically swapped it out with one he brought and it works fine now.
Already did look at that when the orignal one I had there stopped working. It doesn't make sense that the box I have in another room works where ever I put it and the one I got from comcast recently won't work anywhere.
I had a digital adapter that stopped working, so I went and got another one set it up activated it and nothing. So went and got another one and same thing it's activated with a solid light on and just the one moment please message on the screen. I have another DTA from another TV and took it to this TV and it works so I'm at a loss as to what is wrong here. Any help is appreciated.
