Do Plasmas require different signal strength?
We purchased a Panasonic 50" 720p Plasma HDTV 2 weeks ago. We got an HD receiver from our cable company, but the cable company is unable to activate it -- we can't even get it to recognize the time of day. Thinking there was a problem with the receiver, I hooked the coaxial cable directly from the wall to the TV. During the auto channel scan in setup, only a few channels appear (very snowy) and after the scan is complete, no channels are available.
It seems like a problem with signal strength. That could explain the converter box problem, too. When the cable is plugged into the old 20" Sanyo analog TV, it works fine.
I connected a DVD player to the TV and get both sound and picture, so I don't think the new TV is defective.
Is it likely that a signal strength that is adequate for my old TV wouldn't be for a 50" plasma? I've scheduled the cable company, but they can't come until Oct 15!
