Try removing all HDMI cables and then "remove" the power cord for about 10 minutes (powering off is not sufficient ). Then Plug in the power cord, then one HDMI cable and try your device that way.
Also, something to note there is a known flaw with these tv's that cause a spike on the motherboard that cause the HDMI ports to stop working altogether.

Look under ratings and reviews.
Hopefully the reset will get you backup and running though.
The board replacement is not hard either though.

Thanks, the powering off for a few mins worked.
The solution sounds crazy but remove the main board and bake it in the oven to allow the weak solder joints to reflow, it will normally last about a year or two depending on use, when they go out again, repeat.

Hi,
Can you prove that the device(s) that you wish to connect to your TV using a HDMI connection are working via HDMI by connecting to another TV? Have you tried using a different HDMI cable? have you tried all the HDMI connections on your TV?
