Looking inside a CRT monitor

When we purchased our Apple IIc, it came already partially cracked open along with its monitor. Because it was pretty much useless otherwise, we thought it would be a good chance to tear apart and see what was inside of a CRT. Here's what you'll find.

Where today flat-panel LCDs are the basic monitor of choice for computer systems, CRT monitors dominated for decades. Based on the same technology made to build TVs since the 1920s, CRTs have pretty much gone unchanged for 80 years. About the only difference you'll find between a computer monitor today and a TV from the 1950s is the solid state electronics today that make up the interface between the display tube and the tuner in the case of a TV or the VGA interface in the case of a monitor.

CRTs aren't the type of things you want to just crack open and look around inside. There are usually high-voltage capacitors that don't discharge for a long time. It's easy to get zapped if you're not careful.

When we got our Apple IIc for the Apple IIc Cracking Open Gallery, it came to us complete with an Apple IIc monitor. Both of them were damaged in transit. The monitor's case was cracked enough that it would have been unsafe to operate. What better opportunity to see what was inside a CRT.

So that's what we did.  Check out the Apple IIc  Monitor Cracking Open Gallery.
