Not exactly sure what you guys are talking about, especially since I can't see the picture that is supposed to be attached to the first post, but I'm guessing you're referring to the "White Screen of Death"???

If so, I had that happen a few times on my 770. Every time it happens, I simply leave it on and take the battery out while the power is on. Leave the battery out for a minute or two, then everything seems to work fine once the battery is back in.

Maybe something worth trying.
