Blank/White Screen Had put the phone for charging. Everything was fine before. Post charging observed that screen has gone blank(white), while all functions are possible (receiving calls, making calls, etc.).....i.e., without the assistance of screen.

Some good advice from someone who has been looking for this solution for many months, FORGET jumper solutions because you are just wasting your time with this and forget reheating the board as well.
I do not have a diagram to upload but those of you should know where the black bga chip is on the left hand side of the keypad system connector, that is all you have to replace, no jumpers needed. I have just finished my fourth N70 in this way, just change the chip and nothing else.
you can also find the chip on 6680 board.
