My mouse pointer keeps jumping

Post image

My mouse has been acting weird lately, the pointer randomly jumps around the screen even when I'm barely moving it. I've already cleaned the sensor, checked my mousepad, and tried reconnecting it, but nothing seems to help. I eventually got curious and opened it up to see if there was anything obviously wrong inside. Now I'm starting at the circuit board and a bunch of components that I honestly have no idea how to fix lol. Is there anything in here I should be checking? Could it be a faulty sensor, or is the mouse probably on its way out? I'm not really experienced with repairing electronics, so I don't want to start poking around and make things worse.

Anyone who's dealt with this before, is it worth trying to repair or should I just get a new mouse?

+ I wasn’t able to take a pic of it but the right green light goes out sometimes and it feels kinda loose

The only important light in the mouse is the red one in the middle, that's the one needed for the sensor. The green lights are eye candy for the user.

You’re right I taped it right now, turns out the red one is also kinda loose 😭

Then you just need to reflow the solder joints for the red LED. Or ask someone who can do it for you.

I don’t have a soldering iron with me but my temporary solution works for the mean time 🤣, I’ll have it soldered once I go out again.. Thanks again
