My screen goes white/blank for no reason. To get it back I have to shut down the phone, remove the battery and then boot it back up again.

Remove the battery and open the case. Look inside the computer with a flashlight to see if any of the capacitors are busted or leaking from corrosion. The capacitors look like little battery towers, but they are not as tall as the AA or AAA batteries.

If the capacitors are bad, your computer goes bunkers.

Possible that the software of the phone is corrupt or a possible hardware is defective.
You can remove the battery and memory card, have the card scanned for virus. replace battery after 15 minutes so that the phone is reset.
if the phone wont boot back the services of the Nokia support must be sought for reinstalling the software.

what is flashing

Try removeing the battery for a minute, didn't you store your contacts on the simcard? no its unlikely to get the contacts back if the phone has a hardware issue.

Do you have warranty on it? do you get any start up sounds out from it so this could be a faulty screen?

can you do formatting? format it now, their is some program have deleted in your phone. i can format a cellphone, but in nokia. maybe i will find a way to solve your very little problem. i have a problem too! can you solve it? my problem is your phone.

its the FLEX CABLE! need to change it..the cable that connects the LCD screen to the main motherboard

I have managed to fix the problem by doing a software update.
I stumbled across the solution..........I had the phone connected to the computer when I started it in the 'boot loader' screen as opposed to just turning it on. This time the computer recognised the phone was connected and through the motorola software update program I was able to update the software and the phone now works fine.
BTW I did lose all my address book, messages etc.
To start in the boot loader screen hold down the * + # + pwr keys all at once.

Try to update the firmware. you need to flash it using RSD lite software and you can download this for free on forums related to motorola and even firmware is available there.

Hope this info helps

take it to a store and see whats wrong if you sont want to check inside your phone and see if the sim card is broke or if theres a wire or something
thanx Elise

i have a razor vx3 that was doing this every time i would get a phone call. I returned it for a new phone thought att.
