Advertisements Last week I developed problems on a few channels (in the 570's in case that matters), pixilation and “searching for signal V52 error” After checking cable connections, rebooting, etc, VZ phone rep said it was a bad cable card in my Tivo. They sent a new one overnight. I could not active the new cable card using the automated system. Phone rep finally got it to work, it seemed. But within a day some channels went back to pixilated or no signal. Also sometimes the cable card conditional access menu (black and white screen with codes) just appears when on some channels. I get Val:? In card diagnostic screen which I understand means pairing is not complete. I reached someone via the VZ chat on Facebook (which they seem to use now more than DSLReports), and they said it seem paired properly from their end. Also rebooted ONT. But Val: ? still here and some channels are bad. They say it is probably a Tivo hardware issue. Refurbished Roamio from Weakness is literally days out of warranty. Any thoughts? I'm afraid VZ will just blame Tivo, who will say have Weakness replace, who will blame VZ.
