What's with the bright flash of light, then nothing?

[AC Question]

I have a G900v. When I hit power, there's a bright flash of light, the soft keys light up but the phone doesn't wake up! This happens EVERY TIME I try to use my device. When I hit power again, to turn off soft keys, there's another bright flash and the soft keys turn off. I had to push power 195 times last night to get my device on. NEVER dropped, NEVER wet! HELP ME, HOW DO I FIX THIS???

What happens if you continue to hold the power button after the flash?
