Hi Dylan, Good move getting "Dead Mac Scrolls"; it is *the* Mac repair book to have for compact Macs. I have a Mac Plus that also shows similar symptoms to what you have described, and giving it a small whack on the right side of it seems to get the CRT to kick in again. That usually means that a cap may be coming loose from the board somewhere. If you're willing to tear apart the Mac to look inside, check all the caps and make sure none are loose or leaking. Any loose ones can be re-soldered and reinforced, but leaking ones will need to be replaced. Again, see what the book says. If the Mac starts making a "beatbox"-like bong (it'll sound like BEEE-buh-buh-BEEE-buh-buh, etc.) then there may be a more serious issue at hand. Mine does this on occasion, but I haven't had a chance to really sit with it to see what could be wrong. --Robert -- Nobody's ever lost in life...they're merely taking the scenic route. ============================== Please avoid sending me Word or PowerPoint attachments.
