My blackberry 8100 screen is blank and white, how do i fix it

For this problem contact your mobile service provider....

We suggest you to reinstall the software and check the handheld. If you face the same problem even after reinstalling the software, you need to visit the outlet where you have purchased the handheld to service the handheld

my pearl comes on but it has a blank screen

Try this, it solves the problem for Blackberry Bolds:

replace it... Google blackberry replacement parts.

Other than that take it in... and get a new one, you will have to pay full retail, water damage isn't covered.

i want to change the network code of blackberry peral 8100
how i can unloack the phone
IMEI = 355767018968151

Try performing a hard reset: remove the battery from the device while it is still powered on, leave it out for 30 seconds, then reinsert.

Well, after doing more research, I found the answer! You need to buy a new LCD screen for your blackberry. I bought mine on eBay, i.e. http://cgi.ebay.com/Blackberry-8100-Pearl-Original-LCD-Display-Screen-Tools_W0QQitemZ290254550103QQcmdZViewItem?hash=item290254550103&_trkparms=72%3A552%7C39%3A1%7C66%3A2%7C65%3A12%7C240%3A1318&_trksid=p3286.c0.m14

Make sure you get a screen with the tools, there are very small hex screws, but my tool sucked and I barely got the screws back in. There is also directions on youtube on how to replace the screen, you will have to take your whole phone apart. But it fixed my problem and my phone has worked great ever since.

I also got a rubber case to put on my phone, I have a TERRIBLE habit of dropping mine (hence why my screen broke to begin with) but I have dropped my phone a few times since, and the rubber really protects it, I got that on amazon.com.

Anyways....good luck! :)

Using blackberry desktop manager, backup information on 8100 and restore software.

Redownload sw to device, depending on your provider they may have sw listed on there web site, install BB Desktop Manager, download run Handheld Software, run applications loader and download latest sw. Good Luck
