Welcome to the CRT page. Here you will find a list of CRT manuals and diagrams for repairing most CRT's found in both newer and old arcade machine units. So, what is a CRT anyway? How does it work? Below is a diagram of a CRT showing the internal components.

Well, CRT stands for Cathode Ray Tube. Inside the CRT is an electron beam which passes along the screen. This is why, when CRT monitors are photographed, a moving line is visible. When this beam passes across the screen, it activates phosphor dots on the inside of the glass tube. This is known as the dot matrix. This technology is very old, and has been in use since the early days of color TV.

Why use them in arcade machines? Why not just chuck them out and replace them with modern LCD screens? Well, you can do this if you want to. However, due to the resolution of the old games and the how the old video interface circuitry worked, the quality of the picture will be greatly reduced when viewed on a higher resolution LCD.

There's a lot more to the wonderful world of CRT electronics and repair than whats just been outlined above. There's plenty of videos and learning resources out there on the internet.
