Dear mac lovers,
I got a badly recalled LC what could just chime, no screen, no boot, no sign of activities.
I removed the radial electrolytic capacitors, I washed the MB, added the SMD tantalum, except for the 100uF (non tantalum SMD) and the 1uF (radial).
It is back again "bong", screen, pointer ... but:
the ADB does not work, i.e. mouse and keyboard does not work.
the SCSI2SD shows some issues, the led flashes very faintly after the initial bright blink, after a few seconds I have the questionmark floppy icon. Internal of external SCSI connector does not change the behavior.
And it does not bother the floppy either.
The previous guy reconstructed a couple of traces because two pads were corroded, I checked the continuity and those were just fine.
I do not have the schema to check which capacitor are related to these issues.
Can someone put me in the right direction please? Can I test the ADB, the SCSI? Would a picture of the MB help?
thanks
