A longshot, but are there any mechanics on fluther?

Here’s the deal. I have a ‘99 Honda Odyssey EX. I just went outside to move it, and the fuel gauge was sitting below empty. I had just driven it 2 hours before and it was half full. So, I was worrying I might have been siphoned, when I saw that the odometer (on which the backlight was still working fine), also was not displaying either my total miles driven or my trip meter…nothing…nada…no numbers on the little LED screen. I thought maybe it was a fuse, but according to the manual, there is no fuse for either of these things. Anyone who knows anything, I’d really love to hear it as I’m taking it out of town for the weekend and am a bit worried about not knowing how much gas I have or how much I’ve driven.
