That’s the first thing I did. Always need to do them on the analog boards. But I’ll check again at least it’s not blowing the fuse :) thanks for the hint and comment
@Retro4u Also check the capacitors. If they are good, then the flyback transformer is dead or going to fail. Heavily used Macs have flyback issues. I believe you can still find replacements.
Nice video, hope You will fix it fully :) I never liked repairing power boards.... Cheers!
Yeah me as well. Least it’s not blowing fuses now
Good find!! I would start with looking for bad or dried solder joints. Especially around anything high voltages

@RudysRetroIntel well check them out thanks 🤩.
Where's the Commodore videos gone ? Lol ... I hope you get it fixed 😉
WIP 🚧 wasted so much time on the harlequin again :)
It's a step forward. Do you know if the output rails have the correct voltages?
I need to check that for sure. I am aware you can check on the fdd port :) thanks for the comment
