Remove the battery cover from the back side of the cell phone. Remove the battery from its compartment and set it aside.
Use the screwdriver to remove the Phillips-head screws from the back panel of the cell phone. You may also need to remove the antenna from its retaining slot and remove it from the cell phone if you can
Separate the back panel of the cell phone from the rest of the cell phone's body. Place the cell phone face up and then remove the cell phone's faceplate from the rest of the cell phone. This should leave the LCD screen, keypad and circuit board completely exposed.
Tilt the LCD screen downward and then disconnect the LCD screen's ribbon cable from the LCD screen and set the screen aside.
Repeat this procedure in reverse to replace the LCD screen and reassemble the cell phone.
The reason your phone is showing white display is because the flex of the phone is faulty.

The top part of the phone (PCB and LCD screen) can now be removed
from the middle chassis,
A metal frame surrounds the LCD screen. It's held on with clips
around the edge of the PCB. Unclip and remove.
You can now remove the LCD screen. It's attached by a ribbon which
connects like a plug and socket. Simply lift it upwards and it'll
The ribbon which connects the screen to the panel you just removed is what needs replacement, it is attached to the screen so you have to replace the screen, if there is a way you can replace only the ribbon, that would do just fine,
1. Take out the battery
2. unscrew the four torx4/torx5 screws including the one under warning
label but no need to touch the phone idenity label ;)
3. unscrew the two side screws located near top
4. take out pen and any card in device

6. looking at the phone LCD down so you see the circuit board remove
screws (small Phillips/ cross-heads silver in color).

3. Slide phone fully open and now you are able to see all 4 torx screws
that hold the front part of the phone on just under the circuit board.

try this :
This works on most mini electronic devices like cellular phones and degital cameras etc .
it sounds crazy .
Remove the back (or Cover ) of the phone( or Camera ), battery, and SIM if your phone ( or Device ) uses one , DIRECTLY
Then, with a q-tip (or something similar), dab the connection points (shiny, goldish) on the battery, SIM, and phone. This should aid in drying.
Finally, place all contents in a bag of uncooked rice (separately, do not put back together just yet). it sounds crazy , but it draws the moisture out.
It normally is working after just 7-8 hours, but I would wait 12 hours or even 24 hours before attempting to use (just to be sure).
beware the water damage, despite being dry now, will void any warranties. Also, the phone's hardware is now weakened and if you drop it, the green mother board and circuitry could shatter - so be more careful.
This does work on electronic devices aside from phones as well. Simply tailor it to your device. If you do not have a SIM (Verizon phones, cameras, all others), remove only the battery. If you have an iPhone/iPod or GPS and cannot remove the battery, simply make sure it is all the way off, then put it in the rice bag. All electronic devices react the same to the rice trick.

Unplug the battery. Hold down The * (star) and the #(hash) keys simultaneously. Re-connect the battery, phone will beep and screen will be blank. Press the voicemail (righthand silver key under the lcd screen). As above EEPROM/RAM message will appear. Place handset on base and your problem is solved.
