Macintosh SE/30 M5119 - Year long troubleshooting battle

[GreenBar0n]

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.
