I have a Macintosh plus which had some display problems.

After a while the display went black, squeezing the sides would temporarly solve the problem.

I've been reading a bit and found that weak soldering on the J1-connector often would be part of the problem.

When I opened it up, I found very weak soldering points, at some points there didn't seem to be any contact at all. So I redid the soldering them.

But then, as I wanted to put the anode cap back into place, I squeezed it at the wrong place and it fell apart.

Now I've got three pieces, but, how do they fit? How can I reassemble this cap. I tried putting the screw in the metal "U" and then pushing it back into the cap, but there's a wire coming out of the cap, how does this fit in?

I gues the metal "U" should be enough if it makes contact with the wire, so I've tried to leave the screw behind.. But then after booting I get a happy mac sound, and disk activity but no screen whatsoever.

I checked the C1 cap with a Peak Atlas ESR: 4.01uF and 0.07Ohm, that looks okay?
