Ps4 controller analogue sticks does not respond again after replacement

I have this ps4 controller that its left analogue stick drifts randomly. I changed the resistor wheels but the issue persisted. I then decided to change the stick completely. After replacing the left stick with a new working one. When i tested the controller on my pc, both analogue sticks do not respond again. But other parts were responding fine, while the left stick was just stucked at a drifting position towards the top left hand corner. I do not know if i damage any component during soldering or desoldering. Please i need some help on how i can solve this issue.
