Hello I've got a 770 with a cracked screen, but otherwise the unit seems functional. This isn't the white screen problem, since my screen is many colors now :/. There are a few units on eBay that do have the white screen problem, and thus can be had for cheap. Could I swap screens from one of these units to get a working 770 again? AFAIK, the problem with these units is on the mainboard, not the screen. Thanks.
