I can help with the chip if you can't get one any closer
Big thanks to Mike for supplying the chips, they showed up today and i installed one in my Time Machine
and it now works again.
BUT now i have no sound, i put a connector plug on wrong cn6 (i think) on the sound board.
I done this because ther are locating pins on the connector plug so you get them on right, but the pin is broken, so i have put it on in the wrong position.
the plug has Ground, -5, +5 and 12v then on a seperate plug 2 speaker wires.
So the ground was on the -5 pin, -5 was on +5 ect.
would this damage something, i guess so.
