It may just be the cable so check that out first. This happens more often than you think with HDMI cables. Unhooking and hooking up the same cable works at times too.Well, shoot! The HDMI circuit on my receiver went out this morning meaning everything that feeds through HDMI is non-operational at the moment. I have a "new" Atmos receiver I bought a few months ago on sale to replace this current receiver once it bit the dust, but I dread the thought of switching everything out. The equipment is in a tight corner and not easy to navigate. I may wait until the weekend to deal with it. The optical in/out still works so I'll stream things over the TV and use that optical plug on a disc player if need be in the meantime.
