[Q] Please help! Stuck in Bootloop, power button "stuck", no download mode!!

I believe this has to do with the phone thinking the power button is constantly being pressed...

I'm looking for any advice. My s3 suddenly went into a boot loop this morning. It powers on for a few seconds and turns itself back off.. Doing a little research, came across similar issues online caused by the main board going faulty and the phone thinking the power button is constantly being held down.

I know this because I can remove my battery, put it back in, and without even touching any buttons, the phone will attempt to power up.

I'm currently rooted and can't get into download mode for more than 3-5 seconds before it turns itself off. I was only once able to apply the perfect pressure by squeezing the side of the phone which allowed it to boot normally, but about 30 seconds later, the power menu appeared by itself and it turned off a few seconds later.

Has this happened to anyone else?? Anybody know how to go about fixing it??

Yes,it turns on automatically...i have disassembled the phone and checked the power buttom and it seems to work right,i can't understand where is the problem
Edit. OK,the problem is that the power buttom is hyper sensitive..can i do something to reduce the sensibility?
