    My roller ball stopped working going down????

  • Anonymous Sep 20, 2008

    My rollerball still moves down, but the phone doesn't register it moving, so nothing happens. Can still roll up and side to side, but down is a no-go, and it's like the most crucial direction.

    My rollerball/trackball and cursor aren't really responding to each other. Going up is fine.....going down is the issue. The ball rolls down, the screen doesn't register it.

Same problem, wouldn't scroll down. Lifted the ring pulled out the rollerball and cleaned it with alchohol. Used a cotton swab, soaked it pretty good and rolled it around a bit. Set it back in and it worked like new. Watch how you take it out so you can put it back in the same way.

I popped the ring off of the track ball assembly, removed the track ball unit and cleaned it with a swap and alcohol. Problem solved! Be sure you put the track ball assembly back the same way you took it out.

The only way to fully get it up and running again is physically remove andclean (with alcohol) or replace the part. If you want somebody else to do it for you, goto Blackberry Trackball. If you want to do it yourself, here is a Blackberry Repair Guide that shows how, the part is available on Ebay.

You can purchase a replacement trackball assembly for as little as $6 plus shipping.

Installation is fairly simple.

My roller ball does not scroll down, it goes all other directions but down, it makes it so hard for me to navigate.

take the roller ball out by poping out the silver ring at the top and look on the bottom of the ball and make sure that all of the black rollers will roll and if not clean them.

Roller Ball on side of phone will not depress

Have you cleaned your roller ball? stick a paper clip point in the top of the metal ring and pop your ball and holder out. you can remove the plastic part from the ring and clean the parts wth compressed air and then a cotton swap dipped in rubbing alcohol.

Rollerball will not move to the left direction

i had the same the same issue with my roller ball and found out that some how i got oil or some grease on the ball itself. the way i fixed was i "aggressively" wiped the face of the phone back and forth on a cloth and it dried it up. the roller ball worked perfectly after that. it sounds rough or crude but it works.

Pearl roller ball

It might be a case where the track ball has some dirt or debris underneath it. First, turn the device off. Next, press down firmly on the track ball while at the same time rolling it in every direction. Hopefully that will knock loose any debris. Another tip to try is to wet your thumb with a little water and do the same thing.

If those two options don't work, you may try taking out the track ball and blowing out the slot with some compressed air. Below is a link that shows how to remove and clean the track ball:

Roller ball will not work down.

Cleaning the roller ball with a lint free cloth seems to work pretty well. Lock the hand held and then just go to town on the roller ball with the lint free cloth.
