I sent my X360 Controller for PC (Bought in 2011) to a shop but when I received back the left trigger was always pressed like 1.7k~2k (from 0 to 32k).
I found it strange and instead of sending it back I decided to open (store is really far away and I don't want to pay shipping anymore)
The first thing I noticed was some trimpots on the right analog stick
Then I saw that they put a trimpot on the left analog too BUT BEHIND THE LT MECHANISM(right in the middle of the white plastic, the trimpot)
Because of this the white plastic doesn't have the clearance needed latch into the PCB
Also I was checking the LT potentiometer and looks like it was soldered a bit high. If I solder it a bit low, theoretically should stop the "always pressed" trigger

Should I remove the trimpot on the LT?
Should I just remove some material from the white plastic piece?
Should I Solder the LT potentiometer a bit lower?
