Hdmi input broken?

[Blakeatron]

Set up is - panasonic 42" on the wall, sky hd and xbox wired into panasonic soundbar processing box. Then 1xhdmi from the processor to the tv.

It was all working fine until this morning - sound through the soundbar but no picture. Swapped the back of the tv into hdmi input 2 and its working again.

Tried spare dvd player straight into hdmi1 on the tv and nothing.

Im assuming hdmi 1 is not working anymore, just very annoying as that was the autotune so now have to manually select hdmi2 to get picture up!

Anything i can try or is it a warranty job? Glad i got the 5year extension now!

If its a panasonic you can get the set to skip unused inputs

Have you checked HDMI 1 is not set to skip? May also be worth reseting tv to factory settings.
HDMI devices use a digital handshake to connect so faults can sometimes be software rather than hardware.
