This is my issue, just purchased a new 34XBR960 and hooked it up to my basic cable service and an OTA antenna for HD. When I did the initial set up scan it located a bunch of digital channels which was an added bonus. When I channel surf up through the channels I get a ton of no signals and then every once in a while it looks like I lock on to HBO or some other movie channel, but it is sporadic, usually not the same channels all the time and sometimes the channel stays on until the end of the program and then goes blank with no signal or sometimes it stays on for a few minutes and if I try to go back nothing is there. Very weird, just curious is this is my cable company issue or what? Again all I have with my cable service is basic, no premium channels or anything. Thanks and hope this is the right forum?
