"Arpit"

from the sounds of it, the tuner is not at fault.
THis is becasue you said the picture is still grainy when you use the
vcr, which I'm assuming means when you have the vcr connected to the
AV inputs and using , thus, the VCRs tuner to watch tv. I'd check your
antenna wiring and connectors.



** You are correct.

The OP simply has a bad antenna.

The OP is an absolute dickhead.
