richter35,

Sorry to hear that you can't access your HDMI ports. I'm really at a loss as to why that would be. However, the good news is that a firmware update will reload the entire system. So updating the firmware will reset everything (including calibrations, for future reference) and probably give you full functionality of your HDMI ports.

The new firmware is 2007.0 and can be obtained here:

Keep me posted!
