How to fix Joystick trouble for KORG PA50SD, PA500, Micro Arranger

Many of the KORG PA-Series users experience problems with his joystick. Joystick movement in PA-series generally X (- / + or left / right) for Pitch Bend, and Y (+ / - or front / rear) for Modulation. Actually, in this case the problem is always on the Pitch Bend. Problems with the Pitch Bend is caused by the movement of the Modulation, the Y forward and backward movement causing wires of the Pitch Bend stretched and tightened. It breaks connection between the Panel Board and the Pitch Bend Connector.

Here's I show you how to solve the joystick problem for the KORG PA500 (it's might be analogically same for the other PA-Series), 

• Once the chassis is opened we go directly to the joystick! 
• Open 4 screws that locked up the joystick shell.
• Open one screw that's in the middle of the joystick shell.
• Then remove the pitch bend potentiometer.   
• Uninstall / off the male connector from the potentiometer PCB of the Pitch Bend  
• Cut the three cables precisely at the base of the female connector. In this case, it is recommended for the beginners to mark the position of the cord to prevent reverse in the installation back
• Tape the cable back to the potentio PCB! In this point we do not use connector anymore. 
• IMPORTANT: Give leeway cable spacing, so it's not stuck when the joystick move back (Y-)
