Imate sp5 killed mistakenly

[Guest alienx]

Hi....

For many year my imate was having a problem with its joystick so day before yesterday I though of opening it up in order to fix the problem myself but now I don' know what I did, my keypad is not working I might have broken something that connects the keypad with the main board.............

I have search all over the internet but I fail to find the service manual for sp5........I am pretty good with soldering

Can anyone post a link to a service manual or could someone tell me how to fix this problem.........please

thanks
