I have had my 622 for well over a year now but up until this point I have always used component cables. Well I just purchased a new 1080P TV and I wanted to use HDMI, but the TV says there's no signal with the HDMI. I remember tons of post a long time ago about the 622 HDMI outputs not working, but I've haven't read anything in a while. So what happened to the defective units? Will Dish Network replace the unit for free or what? Yes, I am leasing the 622.
