sleep of death?

[StephKD]

Ever since I got this phone I've been experiencing what I assumed was just freezing when my phone would go into sleep mode and there would be no way to get the screen back on. It would show the big green arrow and say, "Backlight is off," and the only way to get it working again would be to take out the battery.

I can deal with that, as annoying as it is, but now I've got a big problem in which my phone won't even turn on. I've got it plugged in, and the orange light is on, but I can't get the thing on. I've tried removing the battery, and sometimes doing that will cause it to start up partially before turning back off. Then it may or may not start back up on it's own, turn off, start up, turn off. I've already tried my hard reset button...and nothing.

About a month and a half ago I put WM 6.5 on it after a hard reset because my message icon always says I have new texts when I don't, but I had the problem before that. I haven't modded the phone at all.

Help!
