Bad solder job is unlikely, i’d assume the new joystick doesn’t have the same specs as the old one.

The board might be damaged or just the new joystick isn’t installed just right, i couldn’t really tell you without seeing it.

That is impressive, did you cut them somehow? You would have to really burn out the controller with the soldering iron to “damage” these with just a soldering iron. This diagram has a lot of the traces but i don’t know if it has the joystick traces http://www.acidmods.com/forum/index.php?...

You should ask around at a maker space or find someone local to show you how to accomplish this. There are also plenty of youtube videos showing how to accomplish this.

Verify the soldering on the 4 smaller pins from the joystick those are what controls the button action of the joystick

It can be a lot of different things that have gone wrong with the potentiometer in charge of that direction of control

Thanks updated guide

@isbelldl thanks, updated to specify TR9

rubber thing? You mean the lb and rb part itself? or the home button section?

Thanks for the info
