Reference number: CH000489

Monitor clicks, pops, or makes other noises.

Issue:

Monitor clicks, pops, or makes other noises.

Cause:

This issue could be caused by any of the below possibilities:

1. Monitor degaussing.
2. Monitor changing resolution.
3. Monitor syncing with the video card.
4. Monitor warming up.

Solution:

Noise when turned on or off

It is normal for standard computer CRT monitors to make a click, pop, crackle, hum, buzz, or other type of noises when they are first turned on or turned off.

Noise when monitor goes into standby mode

When the monitor enters a "standby mode" or "power savings mode" this is similar to the monitor being turned off. It is completely normal for the monitor to make a noise when the monitor enters this mode.

Noise when opening Microsoft Windows or other operating system or when opening a game

When a computer opens its operating system, for example, a computer opening Microsoft Windows or when a user runs a computer game it is very common that the monitor will need to switch its resolution of the operating system or game. When switching resolutions it is normal for the computer monitor to make some type of noise and/or for the computer monitor to flick or flash.

Noise during normal operation

If the computer monitor click, pops, or flashes while it is being used this is not normal operation.  It is very likely that the monitor may be failing or a component within the monitor has already failed and could also potentially be a fire hazard. We highly recommend that the monitor be repaired, replaced, and/or looked at by a qualified technician.
