galaxy s3 not turning on

[1benlawrence]

my samsung galaxy s3 running some variation of a cynanide rom will not turn on at all. i rebooted the phone as the camera stopped working and rebooting always used to fix it, the phone turned off like normal saying it was unmounting the sd card etc and then it wont turn on, ive tried 4 batteries and 2 chargers, i tried those batteries in another s3 and tried connecting to a pc, ive left the battery out over night and left the battery in for about 8 hours and nothing seems to work. ive tried recovery mode and download mode. does anyone have a fix?

Oooh. It sounds like your device might be toast. Can you get into recovery mode at all?

Take the battery out and bang it on a table a few times. Sometimes the power button gets stuck which is not visible.
