I have a Old Sixaxis controller whose Left stick is failing. Normally Both Sticks on PS3 controller are in straight upright position. When you move stick to any direction and leave it, the stick get back to straight upright position. My left stick continues to bend slightly upwards. As a result my gameplay movement automatically drifts in upward direction. Like in Call of Duty, my when i am moving forward and suddenly wanna stop by releasing the Left stick, but my player will continue to drift forward slowly. Only when i forcefully put my stick to center, then player movement will stop. Is this fixable? As far as i know, these sticks are like welded on Sixaxis/DS3 PCB and these cannot be separated or opened up.
