My HTC Amaze 4g will not turn on.

[AC Question]

My phone went in to camera mode and would not exit or turn off. My power button has not been working for a couple weeks now. I decided that I would take the battery out and put it back in. Now it will not turn on at all. Its charging light is fine, and the green light has even been displayed. I can not get it to turn on, please help.
