TV wont detect HDMI Devices except a pc.

Something is wrong whith the HDMI jack it's self, or the electronic switching is not sensing a signal is present. In either case the board that has the HDMI jack you are using needs to be replaced. Most all these boards are double printed, Multi-layered or both which prevents replacing the jack it's self. I do have a question though, do you only have on HDMI jack on the unit or do you have another one available.
