Wow, 20's, a receiver, and now a truck? You heard the economy is in the dumper right? Good for you man. Maybe you can single handedly pull this country back. Please don't tell me you live in Canada. I've liked you up to this point.
Ok, I think you need to tell your TV that the signal is comin to it on HDMI 1 or 2 or where ever you have the receiever connected. Do this with your TV remote.
One night I leaned on my remote and spent an hour getting that straightened back out. Coarse I had downed 5 or 6 rum & cokes. Alcohol makes me smarter.
Do you have a cable box. Are you hearing any TV or movies or anything through your receiver? Do you hear the dvd's but get no picture?
Are you going from the cable to the receiver, then to the TV?
Sorry if some of this seems really simple but I'm trying to cover every base, and we haven't confirmed your Canadian-ness.
