How long does it take for a CRT monitor to discharge if allowed unplugged?

A CRT monitor can take anywhere from a few minutes to several hours to fully discharge after being unplugged, depending on factors like the monitor's design and the residual charge in its components. Generally, it is recommended to wait at least 30 minutes to ensure that the high-voltage components are safe to handle. However, certain components may retain a charge for longer periods, so caution is always advised. For complete safety, it's best to discharge the monitor using proper techniques before servicing.
