I connected the bunk TV directly to the wall antenna jack and voila, received nearly 30 digital / analog, and a few HD channels. Took the access panels down and saw a mess of coax jumpers, splitters without leads, etc. More tonight as I bring it back to OEM as a start. I did trace out an orange coax to outside TV, a tan coax to master BR, so its moving along. Have yet to try the console Clarion for DVD.
