My ViP622 HDMI port suddenly died after nearly two years without even a single problem. The HDMI test function is less than satisfactory, since there is no longer an available "HDMI reset" menu item. Is there any available reset other than a reboot (which has been tried without success)? The HDMI cable hadn't been moved for months prior to the failure, and changing the cable doesn't solve the problem. 6.13 software, and a Samsung 52" LCD televison. Thanks!
