I have a Blackberry Bold 8800 and I cannot use my trackball to move left or right and top or bottom. It was working OK previously but yesterday all of sudden it has stopped working. Please help.
There are threads about this somewhere... but you can pop off the little piece that holds the trackball in. Once you do that, clean the rollers(2 of them) inside real good.
Could be...but it is worth the time to try and clean it.
Exactly. Could save yourself a lot of money if that's all it needs. My old 8130 had a trackball issue too, and I cleaned it out and it worked a little better. Granted, there was some wear and tear too, but I got a little more time out of it before I had to replace the ball holder.
Yep that generation of BB's (81xx/83xx/88xx) was so much easier to clean, or even to disassemble altogether.
Cleaning those roller wheels will do the trick. Periodically wiping the trackball with an alcohol wipe will extend that time even further.

As many have said, cleaning it should resolve the issue. I always soaked mine in isopropyl alcohol for 30 minutes, using the cap as a basin. Then I worked the ball while still in the alcohol in each direction. Take it out, shake it and let it dry for 5 minutes, then install it back in the phone.
Eventually, no matter what, you will need to replace it. Don't go cheap. For $5 more you'll get one that lasts much longer, and performs better.
