Unhappy Nokia 6630 screen fading to white


Hi all... I've watch all this forum and i don't found an answer. I have a 6630 having this problem:

When i power on the phone start and work perfectly. after an indeterminate amount o time the phone stop to work and all the screen start to fade in white.
there is no way to power off with the switch.

After this when i turn on the phone appear the white screen and i cant use the phone.

The only way to rebirth it is to unmount the matherboard clean with antioxidant and remount the phone and also this don't work everytime....

I havn't any kind of tool for reflash this phone, but i made the phone flashed by a nokiacenter, they upgraded the firmware but the problem remain...

I think i'ts an hardware problem but i really cant understand what!!!!
Thanks for an answer

Hi

Yes in good condition but i recommend you to change it.

If you don't have it, just desolder it & wireing on PCB.

It will work 1000% i tested .
