I did not measure.

I replaced the logic board caps on my 8500. All of the caps visually looked ok. But some of them had moisture underneath and fish smell. I think the smaller 10uFs were worse than the larger 47uFs.

Lots of trace fixes. The battery had leaked all through the onboard memory and damaged many of the traces. I replaced all of the memory chips and had to add some bodge wires.

Cool.

Check the output of the pass through port with a multimeter to see if power is getting there. If not, there’s a relay inside the PSU, usually an Omron part, looks like a rectangular box about 3 cm x 1 cm x 2 cm. Has four pins, one provides power to the passthrough port. Another is from the main...

There were different PSUs (and possibly revisions too). The list above was from a Sony PSU. I have done one M1297 and two M0401s. I just looked and found a cap list from one of the M0401s. Board B is different for the M0401. Board D looks the same. But the PSU was not a Sony and is different...

I also removed the boards. My LED came off rather easily as the plastic holder was cracked. I replaced the LED and hot glued it in place. Could have 3D printed a replacement holder but opted for the hot glue. If you running with only one card, you might get away with a Noctua but if you plan...

A bunch of us have rebuilt battery packs with new NiMH cells. I get two hours with mine. As @finkmac mentioned, you won’t be able to revive stock ones. For the rebuild, the main issue is finding a battery where the cells haven’t corroded the EMM circuit board and chip inside the battery. If that...

👏

Nice, have fun!

Not sure if you noted the cap specs in your monitor as you removed the old ones or whether you just used the list from TinkerDifferent. I found that list from TD had an error in it. I noted it here. You might want to check. Post in thread 'Wanted: Cap list for M1212 Macintosh Color Display'...

Yup. I had mixed results though.

I did a crystal change with the stock CPU. Been running great at 40 with no serial port issues.

You should be able to test the resistor. The yellow/black wires are to the fan. The thing you are referring to as glossy is just hot glue. There is a bunch in that area to hold the caps rigid as well as the fan wires.

Awesome! :)
