Hp Mixed Reality Controller Help

[AthruNe]

My brother bought an hp mixed reality headset a couple years ago, and it came with a somewhat faulty right controller. The trigger didn't click the same way the one on the left controller did, and it turned itself off sometimes but it worked fine otherwise. After a while, it stopped working. It will turn on, but it won't go into pairing mode when you push the sync button. I've tried factory resetting it, but it just won't go into pairing mode. Another thing, when you turn the controllers on they will vibrate twice in quick succession. What I've noticed is that the right controller (the broken one), vibrates a bit harder than the left controller when you turn it on. 

Anyhow, I took apart the right controller (broken one) using this guide, (https://www.ifixit.com/Device/HP_Windows_Mixed_Reality_Controllers_TPC-Q044), I found on Ifixit's website to try and figure out what was wrong with it. And I found a loose screw floating around in the controller. My guess is they somehow left it in there during manufacturing. This screw was stuck on a magnet that was on the back of the trigger, so every time you pushed the trigger, you would hit the joystick circuit board with this spare screw that was stuck on the magnet. This was why the trigger felt different to push than the one on the left controller. It looks like it left some scratches on the joystick board it was hitting, and when I compared it to the board on ifixits guide, it looked like the screw might have hit some resistors off the board too. My guess then is that this screw either broke a connection by scratching the board, or it knocked some resistors off, which is whats making the controller not go into pairing mode, and maybe why it vibrates harder than the left controller does when you turn it on. I checked around in the controller and I didn't find any other damage, (as far as I can tell), other than the where the screw was hitting the joystick board like I mentioned before. I really don't know much about electronics though, so I thought maybe you all could help me figure out how to get this working again. As I'd really like to use it to play some vr.  If you could leave a reply with some helpful advice, I'd really appreciate it!!

Sorry if I should have posted this somewhere else, I'm new to the forum!

-I Included some pictures. One of the damaged joystick board where I outlined the damaged area with red. I also outlined where I think some resistors are missing with yellow. I also included a picture of the trigger with the screw I was talking about that was stuck on the magnet.

If you can find a replacement board for it, that might be your best bet, unless you can somehow test the circuit from A to Z. Unless you really know what you’re doing this will be tough.

If the screw short circuited some pins on the controllers they might very well be fried, so you can’t be certain it will work just by replacing some resistors, if that is what you thought.

Yeah, I was thinking that might be easiest. I just don't know where I would get a replacement board from, so I was hoping I could fix it without replacing it. If you know where I might find a replacement board though, then hey, I might just do that. Thanks for the response!
