VGA adapter crashed my ipad now it won't turn back on again

Hey there guys and gals,
I connected my iPad to my Panasonic plasma TV's PC port using the VGA adapter. I was watching a youtube video. I left the room and when I returned a few minutes later after the video had finished and the TV was blank (no problem there as the video had finished), but my iPad had switched itself off and now won't turn back on again. It's completely unresponsive. There was about 35% battery left.
Can anyone help?! I've used the adapter with this TV many times before with no problems whatsoever... weird.

I'm going to assume that you've already tried pressing and holding the Sleep button for 10 seconds or so.

If that didn't do the trick, have you tried pressing and holding the Home and Sleep buttons together for several seconds? That would be a hard reset.

If that doesn't do the trick, you're probably going to want to either call Apple or take it into an Apple Store.

Holding the home and sleep buttons - until you see the Apple logo - it can take up to 20 seconds or little longer on mine.

Hey there guys... whattaya know - it worked!
I must have held the buttons down for 19.5 sec before posting... ;-)
Thanks a bunch for your super-speedy help.
