Blackberry Curve 8520 -
Dropped it, cracked the screen. I replaced the screen with a brand new LCD and put a piece of electrical tape over the solder points on the motherboard in case it was short circuiting. After I put the battery in, the red LCD illuminates and a few seconds later, the screen will light up. The LCD show a blank white screen (no hour glass) The screen stays white and when the phone is on, you can hear the sound of the battery low warning. If i press any button, i can hear a very quiet buzzing sound when the button is pressed and if i put the speaker right against my ear(Very quit buzzing).

(I must add that it cannot be the screen, the old cracked screen started up white aswell) Any suggestions?

did you make sure you bought the right screen, they have different screens, like 005/004 or 007/011 etc
