So apparently forum notifications were turned off and didn't see this response. I replaced about 5 capacitors so far. The ones below that have an orange circle over them. Regarding the other troubleshooting steps. I did confirm that the power switch works with a multimeter. That should be...

Here is a copy of my shopping cart. It includes the counts I I show above. That being said I'll probably add +1 to every line to just in case I mess something up I can have an extra. https://www.digikey.com/short/59p007p4

Here are the caps on the brown board. Not sure what it does. Also, I'm a bit out my league on this capacitor stuff. I matched each value on digit-key based, selected Panasonic when I could, and match approximate physical size. Things like ripple I wasn't sure about.

I took the image from another thread. The list of values was not my work but I confirmed it matched my board. The hexagons were values that were not listed on the graphic its self. The hexagons were effectively my "to do" list of values to look up. I did that and added each to my cart on...

Before digging into re-capping. Thought I would follow this block diagram and took off the power filter. There is some sort of white residue on it. Something leak?

The little brass "claws" go near the AC outlet to help ground everything.

Hey All, Got the new PSU from eBay. It was NOS, but the largest capacitor was bulging and basically gave me the same readings as my original power supply board. Tried leaving the unit plugged in for the past few days. Not change. Luckily I can return the eBay PSU and get my money back...

It's in the basement on a work table. So its way from small hands and I'll be extra careful. The analog board is the one that drives the CRT, right? Are there troubleshooting steps for those or just make a shopping list of capacitors and hope for the best? I'll leave the computer plugged in...

I'll just put the original power board back in, none of those are bulging. I did read about that method. I just put the original board back into the chassis and plugged it all in. Another thing I noticed is that there are labeled points for 130v and 75v. Neither of those (on either board)...

My aunt recently asked how to get rid of her old blueberry iMac and I said ship it to me! It showed up in the original box with all the accessories, except it won't power on. No clicks, no bongs, nothing. No signs of life. I found a PDF of the service manual and when through the trouble...
