Have been moving some TV furniture around so unplugged all the xbox and ps3 etc and hadn't set it back up yet. Kids come home and decide to connect the kit back up so plugged in the HDMI cables from the xbox and sky into the panasonic plasma.

When I get home I find the following:

Sky works but nothing on xbox input channel.  I subsequently start playing around with the connections to find that HDMI 2 ( out of 3 HDMI ports ) on telly doesn't now work at all - have tried skybox, ps3 and dvd player with a number of different cables as well. That's problem number 1.

Xbox also now doesn't display on any of the HDMI inputs and have also tried different cables so I'm thinking the HDMI port on the xbox has been fried. Problem 2.

They can't find the xbox avi lead ( Red, White and Yellow connections ) that offers an alternative connection method. Problem 3. I need to buy a replacment..

So...Is it possible that plugging in the hdmi lead while things have been powetred on has shorted both the xbox and the TV HDMI ports?   I can't check if its a handshaking xbox issue as I currently cant connect it up other than using an HDMI connector but I'm guessing even if I buy the avi lead and get a picture etc its a physical HDMI port issue ?

Any pointers or tips that I may have missed?

HDMI carries 5 volts... it's possible. Unlucky, but I have talked to repair agents who see the issue from time to time. You can occasionally see a spark when you pull an HDMI cable out of a TV if everything is plugged in.
I'd try a full reset on the Panasonic plasma (Shipping condition etc etc) and see if it's not a software issue at the TV's end.

Tried that after i initially posted and took it back to shipping state but no difference. HDMI 2 definitely "appears" dead while HDMI. 1 & 3 appear fine when sky Hdmi lead is swapped between them.

Ill know if the xbox has crapped itself once i connect it up using a no doubt expensive and crap signal component cable

Thanks for your thoughts and help

Scrounged an original xbox component cable off a mate. Xbox up and running. Selected a variety of 720P and 1080i ( TV wont display 1080p) and all good. Swapped over the component for the hdmi and black screen !  Tried different HDMI cables that work, tried different HDMI ports that I know work but still black screen.

Can I assume the xbox HDMI has toasted itself or are there any other checks I can perform?

I had this with my parents TV and their Xbox.  Solution was to turn the Television off at the wall for 30 seconds (not just into standby) and then turn it back on.  TV had got itself confused and was not displaying anything on the HDMI ports at all.
