How to Troubleshoot Monitors

Monitors may face picture display problems from time to time. Old monitors usually face with display problems because their parts have used for many years. Despite that, there are also other causes that cause your monitor to experience display problems.

If there is no picture on the screen, you should check to see if the signal cable is connected to the socket. Sometimes, the monitor switch is off so the computer screen does not show picture. It is also possible that you adjust the brightness of the monitor screen to too dark so that there is no picture display. Most of the brightness adjustment buttons are located below the monitor.

If the monitor is not synchronized, you should check the output level. The output level of the monitor should be the same as the input level. The signal timing must match with the requirement of the monitor.

If the picture is not displaying in the middle, you can make the necessary adjustment by adjusting the H-Size, H-Phase and V-Center controls.

If the picture in the monitor is too bright, you can check the brightness control. The brightness of the picture can be controlled by the plus and minus signs. By pressing the plus sign, the monitor will become brighter. If you press the minus sign, the monitor will become less bright. Sometimes, the extreme brightness of the picture is caused by the inappropriate voltage that is transferred to the monitor. The horizontal frequency can also cause a screen to be too bright or dark.

If the screen is shaking, you should remove the magnetic object near the monitor. The magnetic object should be move to a distance place. Magnetic object are objects that emit magnetic energy. Examples of magnetic objects include magnet, and motor.

You should send your monitor to the computer repair center if the above method did not help you to solve your monitor problem.
