What is a potential hazard when servicing CRTs?

When servicing Cathode Ray Tubes (CRTs), the presence of high voltages poses a significant hazard. CRTs operate at high voltage levels, sometimes exceeding 25,000 volts, which can lead to serious injury or even fatality if a person comes into contact with those charged components. This voltage is necessary for the operation of the electron guns that generate the images on the screen, but it also means that technicians must take precautions to avoid electric shock when handling the devices.

In contrast, low heat emission, limited color output, and reduction in screen size are not primary safety concerns during servicing. While these factors may pertain to the performance or functionality of the CRT, they do not present the immediate danger that high voltages do. Understanding the risks associated with high voltage is essential for safe practices while working with CRTs.
