Reparation of an iBook clamshell
Firewire port (replacing the controller) (light
As usual, I cannot be responsible for any damage to
your machines when you will experiment the following
tutorial. And I'm very happy to post here Pascal's
The FW port does not work anymore... even if the Apple
System Information seems to detect it.
Pluging the clamshell into the power plug does not change
So I think it was just the connector which was
Unfortunately, as Pascal describes here, we have to go
one step ahead to solve the problem.
Once the ibook opened... (follow instructions here
and then next
there)... you reach the mother board.
Just upturn it carefully to discover the FW controller
Yes, it is ruined (yellow arrow)...but two resistors have
also been damaged (blue arrows) :-(
The white arrow points to a self induction...now in a
"Manhattan" configuration due to overheat: this prevents the
FW port to be powered.
Another view of the controller: it has been a hot party
there ;-) (see the tracks on the right)
The new controller right in place. (TSB41AB PHP)
Pascal did not give me the replacement procedure.
One thing is sure... he did not apply the "Antoine
Bercovici" tip on macbidouille
here): because in this tip the 2 tracks were detached
from the board and would certainly be destroyed when the
component were cutted off..
He did the operation with a "WACOM" blowtorch which heat
the 4 sides at the same time (what a lucky guy ;-)
As the whole component is burned out, there is no need to
try to retrieve some part of it.
The yellow arrow points to a new fresh track.
Blue arrows point to 50 Ohms resistors which replace the
56 Ohms original ones.
Theoritically speaking, the FW norm states that resistors
must of the "75X" type...which does not mean 75 Ohms, but 56
Wonderfull clear specifications ;-)
He did not have 56 Ohms resistors, so he placed 50 Ohms
ones. Pascal has decided that these resistors must be
But we must change both the two resistors on the bus !
The white arrows show the A couple which runs to the FW
connector, the black arrows the B couple also running to the
The board is also damaged in another spot (blue
The yellow arrow points to the new controller.
Another self induction to be replaced.
As usual, follow the instruction above in a reverse order
to rebuild the iBook.
If you wish to thank or forsten me...
