Well my e650 seems to have a similar problem, apart from it's permanently blank. I can turn on the phone but cannot see the screen. It started a couple of nights ago when it randomly went black while using it. Turning it off then on again fixed it for a few minutes but then it went black again. I took the battery out and left it overnight thinking it maybe got slightly wet or something. The next day I tried to turn it on, the Orange splash screen showed and it even showed the OS loaded, with the alarm going off (A pet hate of mine about WM, alarms build up while turned off, sometimes barraging you with 3 or 4 if it's been turned off for a few days.) Anyway, back on track - I dismissed the alarm but then the screen went black. I turned it off and back on again, this time it went black after the splash screen. Again I left it overnight with no battery, and today when I turned it on it doesn't even have the splash screen, it's just stuck on being a blank screen. The phone is still "working" as I can receive calls and such but as you can imagine it's pretty useless without a screen.

I'm going to give it a few days to fix itself (or perhaps someone might know a fix) but after that I will have to phone Orange. Thankfully I have insurance.

EDIT: I just turned it on it's working again! When loading the screen kept switching between being fine, being on but corrupted and being blank, but now it seems to be alright. Hopefully the problem has passed, but I'm not overly optimistic.

Also, Elisha, I am not using anything called Tornado Power Control.
