I have a Sony 60NX720 on a wall with an hdmi cable running under the house to a Pioneer SC 65 receiver which has been working fine generally. On occasion I needed to pull the receiver out which caused the hdmi cable to come loose such that gray static would display on the screen until it was reseated properly. However as of yesterday I am getting a message on the TV screen, "No signal. Check the external input or select another input". The TV is set to hdmi 1. I thought maybe the receiver hdmi out connector had gone bad but when I connected the hdmi cable directly to a blu ray player, I get the same message. I checked that the hdmi cable is properly seated in the hdmi 1 port on the TV. I do not have another screen with hdmi to test out.
Does anyone have any idea what the problem could be? The only things I could think of are:
1. The TV hdmi port is broken
2. The hdmi cable was chewed by rats. I did have rat problems under the house about 1 year ago but nothing since then.
Any ideas? Thanks.
