TV Receiver Denon AVR3803 problems?

Question

i am currently experiencing problems with my Denon AVR3803 receiver, the picture is not showing even though there are gray stripes on the side to indicate that the cable box is working. does anybody know how to fix this problem?

Answer 1

Try connecting the cable box direct to the TV. If you get  picture, the receiver is at fault. Check the setup menu. Does is have assignable inputs? The video may be mapped to another output.
