It's suck when your trackball become slip and not working. I try simple fix on my Tour 9630 Blackberry by using a straw. Maybe you can solved the same problem like i did. You can follow the step with picture below:
Step 1
Cut your straw sideway position, i used straw with diameter 0,4 inch.
Step2
Put the straw into the trackball by giving a little bit pressure. Rotated the straw counter clockwise and clockwise direction.
Step3
Unplug the straw from the trackball, and clean the trackball using alcohol. I used alcohol 70% by put it on a cottonbud and swap it carefully not giving a pressure to the trackball. Just swap circular direction, in order the cuttonbud removed the sludge.
Voila! your trackball get fixed :)
