Good evening,
I have replaced most of the capacitors on the analog board; these include:
R uf V
C1 3.9 25 with 3.9uf 250v axial
C2 4700 16
C3 220 16
C24 2200 16
C27 2200 10
C28 1000 16
C30 2200 10
C31 220 16
C32 2200 16
C45 470 10
C42 470 10
I have not replaced C11: 10uf 160uf or the four large capacitors in the middle of the board: 100uf 200v.
Also the two components that failed, 2SC3260 and a RIFA metallised film capacitor, have been replaced.
For the first time in a while I reassembled the Macintosh and turned it on. Nothing, no chime or any indication that the Mac was alive. Nothing happens when the brightness knob is turned.
I have tested voltages on the floppy port and they all read under 1.00v.
I've compiled a list of capacitors on a spreadsheet which I will try to upload to the forums.
I really don't know where to start to solve this next problem? Any ideas would be much appreciated!
