I have phone, internet and digital cable thru Comcast. Everything works except for my bedroom cable TV. It shuts off every 5 minutes and gives me the "one moment please" message, but will never ever go back on again unless I unplug the cable box and plug it back in. When it was initially hooked up, the guy said I had a really good, strong signal. Stronger than most. The downstairs cable (with DVR) never goes off. When I call about it, they say they have no idea and have to send someone out. I've had techs out before in previous townhouses and they've never done anything but unplug the cable. Also, I just can't afford to pay for their visit if it's a problem with the wiring or something. The phone tech said I could try replacing the cable box, but when I asked if he really thought that would help, he said he didn't think so. Can anyone help me? This has been happening for months. Every. Five. Minutes!
