Have Direct TV using a Sony Digital Satellite receiver model #SAT B2-2 /Sony Satellite dish purchased in 7/97. I get local channels thru Direct TV. Recently, local channels will show on the Direct TV guide but will not show the names of the programs, just says ''local channels''. If I try to select a local program, everything locks up...I cannot move from the guide, channel surf...nothing..then get an error message saying to ck satellite connection. Direct TV guide for satellite programming works just fine...can channel surf, select programs from guide, etc. Also, when viewing a local channels on the satellite side, programs will frequently cut out...everything goes blank on screen and no sound...will eventually come back on. Non local programs do not have this problem. Direct TV service via phone has no suggestions other than to have us unplug unit and plug back in...they want to send a new satellite receiver to see if that corrects the problem...if it doesn;t they will send someone on a service call to ck the problem. Can anyone tell me what the problem might be?? Seems to me if it is the receiver, it should be acting that way on both the local channels as well as the satellite channels.' Thanks, Laura
