Macintosh SE/30 M5119 - Year long troubleshooting battle

Good effort. Just remember that any exposed copper needs lacquer applied to it to prevent from further damage.

You can use clear nail polish.

I do have the green UV mask stuff, will put that on the spots I scraped, thanks!


Here's my UE8 bodge wire from Pin 10, this goes to the via under UC8:


Going to need to remove UE8 and get rid of that bodge, or use what's left of the existing trace instead, reason being it causes video distortion, or a bulge where the active display occurs at the left and right borders:

The PO adjusted the picture to maximum size on the CRT, I don't have a trimmer tool that fits the SE/30 opening.

Can anyone recommend the best tool for adjusting the video trimmers on these Mac's?

It's not that UE8 bodge wire causing the weird screen distortion in the video above, I just tried SE/30 #2's LB and it's doing the exact same thing. Glad in a way no to have to rework the #1 LB.

Will try an SE AB and CRT tomorrow.

Thinking about getting this trimmer set for adjusting the picture, is there a better choice?


EDIT: Well, this is embarrassing, turns out the video distortion in the video above was caused by the ground strap wire that connects to the CRT screw in the case, the case/bezel hole is stripped and the screw and ground strap were just hanging there disconnected. Connected the ground and the picture is no longer doing that bulge trick. Picture perfect.

SE/30 #2 was really yellow, the bezel was worse than the bucket shown behind it. 8 hours of the 10W UV LED light in a box lined with foil and slathered in 12% Peroxide Creme worked really well once again; like new. I did remove the Apple logo for the process, had one bleach out on an SE previously, not taking any chances.




The video trimmer tool will be here tomorrow - hope it fits - then I can get the screen on SE/30 #1 adjusted back to factory spec.

SE/30 #2 on the left, has the new Noctua fan installed and is currently waiting for the 1.44Mb floppy caps and an eject gear; might get another BlueSCSI v2 for it and 3D print the rear access sled and then call these done. Will allow these recapped boards to burn in for a couple of hours tonight.
