Recently purchased RXV1065BL yamaha; Hooked it up to LG blueray, with Kef 5.1 speaker system; Got most things up and running, then ran the YPAO system, which ran perfect the first time thru; Then got new carpeting and new furniture; Went to run the YPAO system again, and nothing works? When I plug in YPAO connection on front of receiver, it recognizes it, and the auto setup screen pops up; It looks just like before, but when I try to push the start setup screen nothing happens? None of the buttons work, it's like the whole thing is frozen; I've read similar problems on the web, but not of same exact receiver; One fix says to push the "red" amp button which is not mentioned in manual, but my unit doesn't have this "red" amp button on the remote? Another fix states you must have the RGA connections used, not just HDMI, but I don't think that is my problem, it worked fine the first time with HDMI only; I do have the subwoofer to slightly less then half, and crossover max, but again, this shouldn't have anything to do with the screen locking up? please help!
