I just powered up a Mac Classic. Last time I used it, worked perfectly.
Today, checkerboard on the screen, no beeps, fan runs... Pattern isn't
always a checkerboard, sometimes the pattern varies. Seems to scroll
slowly upward.
Any ideas?
Thanks!

Washing the logic board is not a solution. Best case it will work for a
couple of days/weeks.
All the SMD radial capacitors are dead and need to be replaced in orde
Try removing and reinserting any RAM SIMMs and memory expander. The contacts
can get a little corroded and this process cleans them.

Thanks for the tips. I suspect caps.
Just pulled a pristine SE/30 out of storage as well. Similar (but
very small) alternating lines on the screen.
I had these things in my basement and they worked. A couple years
ago, they were moved to a non-climate controlled storage area.
I wonder if that
It would be great if someone had a 'Work Instruction Diagram' to follow or even
photo's how to change the cap's.

You can dishwasher them also. It cleans the goo that actually shorts the
motherboard. Saved a bunch so far that way. No I am not kidding either.

doing their job and you risk damage to the ICs. You can't replace ICs
nearly as easily as caps (if you can even find them).
Replace the caps, clean the board, forget the dishwasher. it's NOT a fix.

Ignoring that it's a temporary fix, do you just run it through a normal wash

hot water) enough?

There are other reasons for the dishwasher, having nothing to do with the
