6600 joy stick problem
 

I received a 6600 joy stick malfunction on up and down only left and right works pls. help....:(

try the diagram care of Yuvi.. check the up and down track.. if the track line is ok it means u have keypad I.C. problem..
but if there is no track line on up and down.. just jumper the line or if u have new a whole set of keypad with joystick much easier just replaced it...:D
