I have owned two Kenwood VR-8070 Rcvrs. The first one worked ok but one of the self-test functions did not work. One of the video inputs failed on the second unit after only a few hours of use. The factory authorized repair shop has had it for a month and claims to be going "back and forth" with Kenwood but can't come up with a fix. FOLLOW UP- Repair shop returned Rcvr with video input dead as ever. The only thing they did was damage an optical input connector.
