DEAR FRIENDS AT (GSMHOSTING) PLZ LET ME GIVE YOU A UNIVERSAL SOLUTIONS for N70 white screen & hang up :

1st, we should know what is mean white screen
2nd, what is the real solution
3rd, how can we apply the solution

1st - WHITE SCREEN means 2 cases:
A) mobile works completetly , but with no lcd data:
REASONS are:
LCD- LCD CONNECTOR -LCD FILTERS- CONNECTIONS -LCD VOLTAGES(VIO-VAUX)- OMAP.
B) mobile only white screen with no validity( no tx,rx- no voice at earphone):
REASONS are:
SOFT WARE -POWER SENSOR- FLASH IC - OMAP


2nd - when we have the 2nd case we can start with soft ware then check if OMAP has the requierd power for work or not, (Vcorea- 1.4 volt)- then we rehot flash ic even if it is isolated (with carefull)- at last may be the reason is OMAP itself



3rd: how can we apply the solution?
here i mean especially if the problem is POWER SENSOR (SMPS), N4200- we have first to rehot , then take out the POWER SENSOR from the board and make the suitable solution from what i`m giving you below :
i made the (vio ) capacitors with the blue colour -
and the (vcorea) capacitors with the green colours
and you have to make the bridge between any one of (vio)s and any one of (vcorea)s- that is of course to give a suitable volt for OMAP power
and we have also to chose the nearest capacitors of both on the board ,
and below you can see i made 3 circles around the nearest capacitors
i hope you`ll like it and it will be usefull for all :

Best Wishes For All Till We Meet Again,
