Answer to: No Signal Error from HDMI connectionsI'm am having the same issue with our 2011 Samsung 58"plasma TV. I have tried different inout, different hdmi cables, factory resetting the cable box, factory resetting the TV, and taking off the back panel and ensuring everything was plugged in snuggly and that dust wasn't a problem... but nothing seems to be working. The TV recognises if the hdmi cable is plugged into a device, but when it detects that device and I am on the proper input source (ex: HDMI 1) it says "no signal." I don't know what else to try. Any suggestions?
