Mine was.VDP07 said:You might also try connecting the 722's TV2 output to your other TV. It's possible your #2 TV's coax connection is bad.
I ran the coax through a VCR and out of vcr with rca cables to Tv. cleared it right up. [ vcr has to be set on same channel, in my case, 73]
TV coax was faulty.
Id try that before a call for service, might save you a few bucks.
