My new TX NR676 HDMI outputs do not work. Main or sub. I hooked up a brand new 18 Gbps HDMI cable and still get no output. I hooked the TiVo directly to the tv and tried all 4 HDMI tv inputs and they work. I disconnected all other HDMI inputs and used the new cable, but could not even access the settings menu on the 676. I ran several of my older cables from the TiVO to the tv and all worked. I hooked up the TiVo with a verified older cable to the 676 and the new cable to the tv and still can't even access the menu settings on the 676. The tv says no signal. HELP? I ran a seperate cable from my Dish receiver and TiVo receiver to two of the tv inputs, so I can watch tv while hoping someone hear can help me.
