Macintosh Classic II no boot

[wagbox]

I recapped my classic II's logic board and it now does the same thing as before (nothing, just the fan comes on which it does without the logic board installed anyway). I'm trying the dishwasher trick now as a last resort.

Do I need to recap the analog board for it to show any signs of life?

yes, recapping it would be strongly recommended

if it's a mac classic 1 or 2 it should be recapped before anything else should be considered (within reason)

Did you measure the voltages at the floppy port?
There are a lot of parts on classic AB that can be defect. Most often: DP3 and DP4 (1N4148), TDA4605, CNY17G, IRFBC40.
And I would recap the AB.
