Hi all! First post here, hoping for some advanced help. Thanks in advance!
I picked up a Mac SE that I'm trying to get working again. It was initially booting to a checkerboard screen:
My first stop was to clean the motherboard (which didn't look too bad) with alcohol, and re-seat the ROMs and RAM and clean their sockets with electrical contact cleaner. That didn't change anything, so although the axial caps didn't look too bad I moved on to doing a recap of the motherboard.
After recapping the motherboard, I now get these stripes:
Here's a pic of the motherboard after the recap:
Thanks for your insight!

Here's a pic of the motherboard after the recap:
- I don't visually see anything wrong with the motherboard (no cap goop, all the traces look OK to my eye) but I'm no expert.
- I don't see any blown or leaking caps on the analog board either
- I disconnected the PSU and tested it with a multimeter (with no load) and I'm seeing 5.3v and 13.8v (which don't seem that bad) but only -8.2v where I think I should be seeing -12v. Not sure if this is normal.
Thanks for your insight!
