Just went and exchanged my cable box for a new one. Because the old cable box was sticking and not showing guide updates and some channels where out.. now that I have a new box it is not working at all.. No picture, the channel on the box won't go past 0 (zero) and it doesn't do anything but show a black screen on my tv. I have called 4 times and I get the same troubleshooting as I have before.. They have activated my box, said they were sending signals to it.. turn it on and off.. wait 5 minutes to do this or that.. NOTHING.. Still a black screen and the box says zero.. no other lights on the box or anything just a zero. HELP???
what box is it? If unplugging it and comcast sending signals to it didn't work either you have a bad box or you have problems with your wiring. I would try to call again and maybe someone who knows what they are doing can help you. how do you have it connected to the tv? try undoing all the connections and then restart and see if anything happens. if the bot won't even turn on that is a box issue.
funny, but I have the same exact problem...recieved 2 new boxes via UPS this evening...connected everything correctly...the boxes stay on "0" and wont shut off with remote or by hand....have been online and on phone for hours with comcast....signals have been sent through numerous ...boxes have been unplugged ....still not working....really dont want a techincian out since an old box that i have works fine when connected to the tvs....
i have took all wires off many times, nothing so i have one of the small box i took from bed room and that works but im not getting what i pay for, i talked to a comcast worker on y=the side of course he told me the wire on them are not heavy enough but id have to get a order in to have them fix it, well i never het past the troubl shooter on the phone to pa, im so readyck up there junk
