TV will not get a picture past channel 41 on Comcast CAble.in in Ocean County, NJ. Prior to yesterday we were able to get all the channels .. yesterday we were not able to see any pictures above channel 41. Previously, we were able to see programs in the upper channels up through the 80's or 90's... any help would be appreciated any suggestions on how to find out what to do to get the tv working for all channels.
