likwise. those guys are the lowest of the low. i lost an original gameboy to scum like that when it was just new out - problem was it wasn't even mines. i had borrowed it because at the time i couldnt afford it. i then had to buy the friend a new one.
anyway my advice is don't try and repair it - its a 2 handed job - honestly it isn't worth the risk. i know youll be desperate to get it working but you could make it worse. you could ask a friend to come and help you with the surgery because it just sounds like something has become dislodged. good luck with it and good luck with your hunt when your all better :D
