Update: Also resoldered the solder joints of the power connector and still nothing. Blah | Posted by: desertrout on 2022-05-13 07:00:56
OK, so no power at the floppy port, no change with fresh solder. Time to start testing on the analog board itself, see if voltages are present where they need to be, starting from the switch and working forward. I'm currently getting ready to leave town for the week, so I can't go in to detail myself, but perhaps someone else can?
It might be worth watching this: . and this: in which Bruce does some analog board repair
Also, get familiar with chapter six of Pina's Repair Secrets, where he walks through power / analog related issues in detail.
Ultimately - take heart! These analog boards are pretty much always repairable, and the process is fun and addictive. | Posted by: Anonymous on 2022-05-16 17:04:35
Thanks for the advice! as for progress, It's slow. I noticed that R31 (R55?) on the analog board is cracked. Assuming this is a problem, would this somehow relate to my dead Mac issues? Also is there any place to find a replacement? | | < 2 |
