| Monitor on my Mac Plus works for a few minutes and then goes black |

Hello, my Mac Plus was working perfectly fine until I opened and dissembled it. After that the computer will boot up fine but after a few minutes the screen goes black. Any ideas what I might have screwed up? Shortly before that I also saw some weird artifacts when booting up from a screen, black and white vertical stripes (pretty thick ones, about 1/10th of the monitor in width).

Try re-seating the ram chips.

It doesn't look the machine crashes (which is what I'd expect from RAM problems). The screen just goes dark, as if you turned it off. I'm afraid I screwed up some cable or bumped into some component on the video board when I opened the machine. I'm not sure how to debug this.

Actually, I take that back. The weird stripes that were showing up initially did seems like some sort of glitch that might come from RAM problems.

Resoler the pins of the cable between the logic board and the analog board. Pin 1 on the analog board is often broken.
