I'm getting one of my HR10-250s ready to sell on eBay and found that I don't get any signal from the HDMI port. I've always used component, so this is actually the first time I've tried HDMI in the several years I've had the machine. As I recall, this was a major issue with this unit back in the day, but for some reason I thought that it had been resolved with a firmware/software update. Guess not. Is there a fix?
