Not joking. Puppy tried to eat the 770. Bad, bad dog. The LCD is cracked and there are teeth marks in the outer shell. As far as I can tell internal parts seem fine, boots up as normal. Not sure what to ask for it, and am contemplating selling on Ebay, but thought the post here might be more helpful to someone who needed it.
If anyone has sold a 770 for parts or bought one, please post suggestions as to what I should ask for price.
I'd be willing to give you the dog for free.

does the LCD display anything? does the touchscreen work at all?

It does light up and the color change of start up screen, ect can be seen. But he cracked the screen good. I'll get pics up if anyone is actually interested in it.
