Everything from "x-ray shielding may be needed when operating at high-voltage" to "high voltage, don't touch that!".Next, I'll take a deep and thorough look at safety precautions for re- capping it. (ie, discharging everything without electrocuting myself before I start poking around)Have a read of this: "The Truth About CRTs and Shock Danger"http://lowendmac.com/tech/crt_danger.html Cheers, Nick.Well, my initial reason for taking it apart was to replace those caps. It's still a possibility if the other things mentioned by Michael (Mahon) don't work. Speaking of which, What do those things look like? (Ferrite core, flyback transformer and yoke) I'm seriously a beginner in all this stuff. What would I need to tighten and how would I do it? What would I apply the lacquer to? Most of my experience is on paper with digital components, rather than opening old stuff and fixing it.
Rather than go into a long discourse, I recommend that you read up a bit on CRT monitors--Wikipedia might be a good start, but any TV repair discussion will cover the ground. You wouldn't pop the hood of your car and start replacing all the ignition wires without reading up on it, and I wouldn't recommend doing it with your monitor, either. Blind replacement of capacitors (or any other component) is actually a grave risk to the PC board of the monitor, and it is virtually certain that 90% of the capacitors are as good as the day they were made. It's always "one bad apple" that causes a problem, and the repairman's job is to find it and replace it. Shotgun approaches are often seen as a "quick and dirty" way to fix problems, but they are never really quick, and they are always dirty. ;-) Remember, it may not even *be* a capacitor causing the problem! -michael NadaNet and AppleCrate II: parallel computing for Apple II computers!
