gyroscope location inside phone?

I dropped my xperia s, gyroscope and compass stopped working. Device goes in deadlock and force shutdowns when I click on compass or gyroscope test in service menu. Gyroscope might got off.

I decided to swat it again. Gyroscope worked for few seconds and again stopped. It never worked after that on hitting also.

Can any one tell me where it is physically located on the board?? May be reinstalling it will do the job?
