Just switched back to xfinity and picture is flickering or pixelating. Had a plug in amplifier with cable attached from previous account but cannot remember if it is for internet or tv. Does anyone know what amplifier is for?
Solved! Go to Solution.
It is an AC Adaptor, Model AD35-1200200DU, Input 120v - 60Hz 45mA, Output 12v 200mA. Just came back to comcast and this was installed previously. My picure is pixelating and I think this was installed before to stop that. Not sure how it was installed to splitter that then went to a 4 way splitter for my tv's and internet.
