Mouse Randomly Scrolls Backwards despite repairs

[pavichokche]

I have a E-BLUE Mazer II wireless mouse I bought in 2014. For 4 years I had no issues with the scroll wheel, and then it started to randomly send backwards scrolls sometimes, along with the proper ones. I cleaned it, and it was good for a little while. I took apart the encoder wheel inside (it's this type of mechanism) cleaned it thoroughly, and again it was good for a little while. Then I purchased brand new encoder wheels and soldered on a brand new one. It was good as new, but again SOMEHOW it didn't last! At this point I'm beyond comprehension how this is even possible.

 

My only guess is that the mechanism is maybe very sensitive to dust particles or cat hairs, because as soon as I take it apart or even just blow in the wheel area, it seems to work normally for a little while (talking a few days at best here).

 

What could this be? Any ideas for things I can look at to replace/clean/cover?

You could replace the whole mouse, by buying a new one.

Spray it with WD 40.

This thing do wonders

im sorry to say but it most likely would be better to get a new mouse that is similar to the one you have.

I don't know why I bother with these forums...

Anyway, the issue isn't the solder joint between the new encoder wheel and the PCB. To test whether or not the issue is dust, I've wrapped the encoder wheel in a piece of plastic. If the problem still comes back, then obviously it's not caused by dust, or at least not dust buildup on the encoder wheel. In that case my next thing to try is to spray and clean the whole PCB with isopropyl alcohol and the key contacts with contact cleaner.

You are probably best off just buying a new mouse

What is wrong with you people, is this a meme or something? Do you buy a new car whenever you get a 'Check Engine' light? The mouse is currently functioning 100% fine, I'm just trying to figure out an issue which comes up sometimes.

[Emanbaird]

The reason they are telling you it's probably a good idea to just replace the mouse is because it is already older, and stuff like this may start to have issues

 

The mouse is relatively inexpensive so replacing it may or may not be the best option.

 

It could be something wrong with the controller even, something shorting where it shouldn't be.

 

if it's just dust you may have answered your own problem.
