Dear all,
I have a Macintosh Classic II that -suddenly- died by being unable to boot; vertical (vibrating) stripes appear when powered-on.
I recapped:
- all surface capacitors of the logic board
- all capacitors of the analogue board
(+ cleaned both boards: logic & analogue)
Still no signs of life!
It could be a malfunctioning logic board (or rom chip?) or an analogue board that -still- provides weak voltages.
Regarding the power output of the analogue board, is there a certain mapping / diagram regarding the voltages I should be reading in each of the pins in the highlighted green sockets?
The purple socket (for the drive) has an output of 4.6V & 11.4V that seems OK (correct?).
Thank you in advance for your time & effort.
