828mk 1 firewire problems

Post by Gonz »

Hi all
My first post here :)
Ive just brought a no go 828mk1 that im trying to repair.
The unit all powers up but the firewire isnt working.
Ive replaced the firewire chip tonight which hasn't helped :roll:
It has tryed to work once as windows "found new hardware" but the machine slowed to crawl and i had to abort the install.
Does anyone have a close up high res picture or could take one of the PCB around the firewire / spdif coxial sockets as ive noticed something looks likes it missing, like a cap or a resistor.
I have no service data so im at a loss at the moment..
Thanks in advance for any wisdom anyone might have on such matters.
I dont think this one is going to come easily somehow...
Cheers
Gonz

Hi:

I have the same problem.I will try to change the female firewire conection, that could be broken because of years working.Sounds simple, but perhaps is the solution. Don`t you think?

Good look

Hi
Always a possibilty.
Im pretty sure the socket on the one i have here is ok.
I measure what looks like the correct signals on the firewire buss around the socket when its connected. Also theres continuity through onto the board ok.
Just a lack of activity...
Would you be up for taking a high res photo of your pcb around the firewire chip and the spdif area?
I think i have a missing component but im not sure.
