I recently purchased the Yamaha RX-V663 receiver. I have connected via HDMI cables my Comcast Motorola DCH6416 cable box and Hitachi 50” plasma TV (P50V701) through the Yamaha’s HDMI pass through. I use a Harmon Kardon TC30 universal remote to control the system.
The problem I am having is that when I power on the entire system, the Motorola cable box which I have set up to display at 16x9 and at 1080i, reverts back to 4x3 and 480i every time on power up. This problem does not occur when I connect the Motorola cable box directly to the TV via HDMI.
I have determined that if the TV is powered on 1st (about 10 seconds in advance) before the RX-V663 and Motorola cable box, this problem does not occur. I believe that if the RX-V663 does not see the TV far enough in advance before the power on of the cable box, the receiver is cycling down the cable box resolution somehow. I have adjusted my universal remote to power the TV on first, but everything is powered on so fast, the RX-V663 does not have time to see it before the cable box powers on. This problem is frustrating and some help would be appreciated. Thank you
