1. Loose cable connection

One of the most common causes of this problem is a loose video cable connection. The majority of electricians agree that a loose or broken video or antenna cable connection, which transmits the signal from the CPU to the monitor, is the main cause of a monitor or TV displaying a no-signal error.

Therefore, the first thing to do if you see this notice on your computer monitor is to ensure secure video cable connections between your computer and monitor. But if your monitor still shows the same error after detaching and reconnecting the cable, move on to the next step.




2. Software Glitch

A Software Bug, also known as a “Software glitch,” is a common issue for almost all electronics, including TVs, monitors, and other networking devices. Generally, a software glitch causes a device to start misbehaving, like stopping working some function suddenly or not working completely.

So your monitor’s operating system may be experiencing a temporary glitch, preventing it from decoding the signal sent by the CPU. In this situation, a factory reset can fix your issue.

You may reset your Onn monitor by pushing and holding the power button for around 60 seconds. It will repair software errors, restore your monitor to its normal settings, and resolve your problem.

3. Problem with the source device

Let me ask you one thing: did you even turn on your CPU? Or you just turned on your monitor instead of powering on the CPU first?

We occasionally forget to turn on the computer after turning on the monitor. Until it detects a reliable video signal from the computer or source, the monitor will show a “No Signal” warning. So, please make sure your computer is turned on.

If your computer is turned on and you have checked the cable and cable connections, but you are still getting a No Signal message from your Onn monitor, check this by:

  • Connecting another display with your computer.
  • Connecting the same display with another computer.




4. PC’s Hardware Issue

If none of the above techniques work and your Onn monitor still displays the No-Signal warning, one of your PC’s internal components, such as the graphics card, is malfunctioning or the RAM stick is filthy. In this case, checking and cleaning can both resolve the problem.

Before you disassemble your PC, make sure your computer is turned off. Also, unplug all cables, including the power cord, which will help you to avoid electric shock.

After then, open the PC’s back case and locate the graphics card first, as this is the most likely to cause a no-signal issue if it is loose or damaged. Then check the RAM sticks. If the RAM stick is dirty or dusty, clean it.


FAQ

1. Nothing worked! What to do?

Unfortunately, suppose none of those mentioned above methods works, and your monitor is continuously displaying the same warning “no-signal.” In that case, your monitor may be damaged, or your PC’s internal component may be broken.

In this situation, go to your local electronics repair shop or call an expert repairer and have him check into it. You can also contact Onn customer support and explain your problem to them. But your monitor must have a valid warranty to receive free servicing.

2. My Monitor shows no signal, but the CPU is running.

If your monitor is blank, but your CPU is active, it’s possible that your monitor isn’t getting a signal from your CPU. The problem could be with the monitor or with the cable connecting the monitor to the CPU.

First, try connecting to another monitor to see if that works. If it does, the issue is with the primary monitor. In this case, you must either replace it or fix it. However, if the second monitor does not work, either the GPU is not functioning correctly, or your display is not receiving any signal from your PC.
