That's how I got into this business! I had one of those old monitors that had to be adjusted internally. Well, I got tired of turning it off and then on while adjusting it, so I decided to leave it on and CAREFULLY adjust it. I go the screwdriver a little TOO CLOSE to the wrong spot and WAM! When I got back up off the floor, eveything seemed fine, but a short while later my vidoe card went out, then my floppy, then the floppy interface, every week something new, and since I could't afford to get it fixed I kept buying parts and fixing it myself. It took me weeks to figure out where that screwdriver went!
