Nokia 9500 no display (power)

[ndagi]

hi dudes,
my staff broke one of the two ESD chips located near the flex strip connector on board a nokia 9500 while trying to change it's housing, As a result the backlight of the inner diplay and the keypads on the phone part were disabled and he tried to remove and peeled one of the pins from the board out.
after we replace new chip phone doesn't come on no more. i've changed about three chips and still phone no power.
It's a miracle this one leg would disable the entire phone coming up as when i check phone status with jaf i get response.i'm also able to read full info of phone.
Please i need this point to be traced as soon as possible as you'all know what the owner of a nokia 9500 thinks he has...... a jet plane

i've attached a picture for evaluation

thanks in advance
