PPC6700 won't turn on out of the blue

[notorious1]

hey guys, i hope this is being posted in the right forums. i didn't see any forums that i thought were dedicated to troubleshooting.

ive had a 6700 w/ wm6 running fine for a while now. a few days ago, it died and wouldn't turn on. i left it plugged in and realized that the battery was just so old that it had been drained almost completely and after a while the phone started working again.

today while i was typing a text, the screen slowly started turning completely white and then i couldn't do anything. i hit the soft reset key and the screen went black and the unit hasn't turned on since. i've tried two batteries and it still doesn't work. its been in the charger for about 30-40 minutes also and that didn't do anything either. im going to leave it plugged in overnight but i dont know what to do.

any suggestions would be very appreciated. thank you all in advance for your help in this matter
