Razer Mamba TE scroll wheel issues

I've had my Razer Mamba TE for a few years now and just recently, it scrolls normally then randomly double scrolls or gets "jittery" when trying to scroll (scrolls down while I scroll up or vice versa). It has gotten bad enough that I end up just clicking on the side bar and dragging through the page because the scroll wheel is effectively useless. I have tried disabling Synapse and tested it on a couple different computers but no improvement. I have also tried shooting a bit of compressed air into the mouse to see if that would do something, again no improvement. It's out of it's warranty so I can't RMA it, so are there any other solutions to fix this? Thanks.
