Check the power button and cables

The first step is to make sure that your monitor is on, as some monitors have more than one button or power switch, it will be up to you to verify that the appropriate button is in the correct position. If this does not solve your problem, the next step is to check the connection of the power cable, as it may have come loose due to a jerk while you were using it. Also be sure to check if there is any cable adapter that is not fully connected to its corresponding port, we are talking about HDMI, DVI, VGA cables, or some kind of adapter between them. These cables use screwless connections, so they can be easily released with a tug or when you move the cabinet where the PC is to clean.

Check for disconnected display data cable connections. Your monitor may turn on without problems, but cannot get information because the cable connecting the monitor to the PC is disconnected or loose. This could be the cause of the problem if the monitor's power light is on, but is amber or yellow instead of green or blue. It would also be a good option to try a different cable, you can buy it in many stores for very low prices, it is a very simple way to rule out a possible failure in your cable.

Adjust the brightness and contrast options if you can

Adjust the monitor's brightness and contrast settings. The monitor may display information, but you cannot see it because these display settings are too dark, making it impossible to distinguish what appears on the screen. Most monitors today have a single on-screen interface for all settings, including brightness and contrast. If it turns out that your monitor doesn't work at all, you probably don't have access to this interface. An older monitor may have manual controls to adjust these settings.

Try another monitor

The next step is to check that the PC works correctly by connecting a different monitor, that you are sure that it works correctly. The monitor may be working properly, but the PC is not sending you information. If the new monitor doesn't show anything either, continue with the next step.

When testing the new monitor, be sure to use the data cable that comes with it and not the one from the original monitor to rule out any possible incompatibilities. If at this point none of the monitors works, now you know that the PC is not sending information to the monitor. In other words, you have shown that it is your PC, not the monitor, that is causing the problem. At this point another component should be blamed, such as a faulty graphics card, for example.

If when testing with a different monitor it is showing images, you already know that it is your original monitor that is failing. The design of current monitors makes them very difficult to repair or even impossible, so the best option is to buy a new one if yours is no longer under warranty.
