I presently have a Blackberry Bold 9000. I took it apart many times before for cleaning the trackball, etc, and then put it back together and it worked perfectly. Now when I tried it again this time, went to put it back together, all I am getting is a white screen, I have all my contacts in there, etc. Is there any fix this problem? How can I fix my Blackberry Bold 9000’s white screen? I would be really glad if someone can really help me regarding this. Thanks.
