I have an sonicview 8000hd.I't's hooked up to a 33in dish with a invacom lnb,steered by a hh90motor.Lately when blind scanning on g18,or any sat,the reciever stops about 20% into the scan.It then flips to the settings page with no writting or anything filled in.On dtv scans it won't even start.Has anyone had this problem before?Should I save all my sat and channel entries and do a factory reset?thanks for any help. tob
