I've had this unit for roughly 6 months with no issues. Today, I turned the related components on as usual and only received audio. Currently, I have an HDMI cable directly from the unit to the TV (Panasonic TC-P50G25) and a toslink connection to my Sony receiver. I switched to my DVD player to confirm video and that was fine. I cold booted my DirecTV receiver and still had audio but no video. I tried my (obviously working) DVD HDMI cable and various HDMI inputs on my TV with the same result. I set it to use only 720p, changing DirecTV channels, and turning the TV off and on a few times with the same result. I then used a composite video cable from my DirecTV receiver to the TV and I had picture. I switched the cables between HDMI and composite with reboots, but only received picture from the composite. The firmware version is 0x459. Any ideas on why I suddenly only have picture with a composite cable?
