When you switch ON your computer, if nothing shows up in your monitor, testing the monitor to check whether it works fine, before the troubleshooting process will save time and you can be confident that your monitor is working fine.
Checking your monitor is pretty simple task and it is a necessary step, as it saves lot of time in troubleshooting, if you find your monitor to be faulty.
- A working monitor (Optional)
- A working monitor cable and data cable (Optional)
I have specified these materials as optional as these are required to double confirm that your monitor is working fine. Otherwise it can be neglected.
1. Check your monitor for the light color it produces
Today almost all the monitors have a Light indication to show whether your monitor is receiving any signal from your computer.
For Example: A monitor may show Blue light when it is receiving signal from the computer and yellow light when it is not receiving any signal from the computer.
Important: This step is important as it can show whether your monitor is receiving any signal or not by looking at the light color.
2. Remove the data cable from the monitor and switch ON
When you switch ON the monitor with the data cable removed, all the monitors will display a message like, “Cable has been disconnected. Monitor is working fine”.
Note: Above two steps will confirm whether your monitor is working or not. Please continue if you feel that you need to double confirm about your monitor.
3. Replace the monitor with working ones.
Replace your monitor with a working monitor and see whether you get any display on the screen. Use the same data and power cable that you used with your monitor.
If you get any display in your screen, you can make sure that your monitor has stopped working and proceed to step 6.
Note: If you are planning to take your monitor to some other place for testing, please ensure that you are careful with your monitor when transporting.
4. Replace the data and the power cable one by one.
This step is confirm whether your monitor cable and the power cable are working fine. Replace your monitor cable and data cable to a working computer and check whether that computer shows anything on the screen. If that monitor shows anything on the screen, then you can be confident that your monitor cable and the data cable are working fine but your monitor stopped working. Now proceed to step 6.
5. Replace your monitor cable and data cable.
If the working monitor does not display anything on screen in the above step, replace the cable with the working ones and check whether it turns ON. If your working monitor turns ON, but your monitor does not turn ON, then you need to replace your monitor cable and data cable along with your monitor.
6. Replace your Monitor.
Important: Do not attempt to open the monitor as it is not a user serviceable device. It contains high capacity capacitors, that can cause severe current shock. If you want your dead monitor serviced instead of replacing it, then please let a professional do it.
