Hey guys,
I recently was gifted a Macintosh 512k for Christmas. I have been using it kind of nonstop, and I noticed that after having it running for a little over ten minutes or so, the display begins to freak out a little bit. The top and bottom edges start to bounce around a little bit and faint lines show up on the bottom and the top of the screen, seemingly mirrored. I've thumped the side a few times when this happens. Sometimes it helps, sometimes it doesn't. The display has never gone out entirely, nor have I ever gotten a thin white line across the screen, but I'm worried that if I continue to use the Mac in this state I will end up screwing something up.
My best guess is that the solder joints on the logic board are cracked, and when the computer is on for a period long enough for the components to start to generate noticeable heat, the flowing heatwaves irritate the already straining connections. Then again, I am relatively new to the world of compact Macs. I know for a fact that the analog board has been recapped, and upon inspecting the logic board, it doesn't seem like any of the capacitors are bulging.
I'll appreciate any and all help I can get. Thank you!
In terms of specs, this is a stock 512k, not an upgraded original. No add-ons have been installed. It has only a 400k floppy drive, no hard drive. I have only been inside it once to grease the disk drive up a little bit. The screen problem predates this.
