1- Power Cycle ONN Monitor

A blinking blue light is one of the most common problems observed in ONN monitors. 

This problem can occur due to multiple issues, and users should try to resolve it immediately to avoid further inconveniences or damage. 

To fix this issue, they should attempt power cycling your ONN monitor by disconnecting it from its power supply for a few minutes and reconnecting it when they are done. 

This will reset the monitor, which may help resolve any malfunctioning issues causing the flashing blue light; if not, users should contact ONN support for additional assistance. 

More severe cases where an ONN monitor’s blinking blue light indicates damage or loose cable issues should be handled directly by contacting ONN support immediately.

2- Damaged or Loose cable

If your ONN monitor blinks blue light, it’s most likely due to an issue with the cable. 

Often, damaged or loose cables can be the root cause of ONN monitor errors and visual disturbances. 

To determine if this is the case:

  1. Try inspecting the cable and ensuring that it’s securely connected to both the ONN monitor and your device.
  2. If the cable is damaged or loose, replace it with a new one.
  3. Once you have done this, power on your ONN, monitor again, and see if the blue light has stopped blinking.

If it has, then you’ve successfully resolved the issue. 

However, if the ONN monitor continues to blink blue light even after replacing the cable, then there may be another underlying issue that needs to be addressed.

3- Check HDMI Cable

If your ONN monitor is blinking blue light, it could be an indication that there is a problem with the HDMI cable. 

This issue could happen if the HDMI cable has become faulty or broken due to frequent usage or if it was damaged from the beginning.

In any case, the initial steps towards solving this issue include checking the HDMI cable and ensuring that it isn’t damaged or faulty before you replace it with a new one.

Next, regarding troubleshooting steps, you should unplug and reconnect the HDMI cable for the solution to work. 

However, if this does not fix your problem, then further inspection of the motherboard may be required, as there might be an issue with the power supply connection.

4- Defective Power Socket

A defective power socket can cause a blinking blue light because it may produce sparks or interruptions in the flow of electricity. 

A flickering light indicates that the power socket may be faulty, as the spark or disruption caused by the defect interferes with regular electrical current. 

An erratic surge in electricity occurs as a result which causes the light to blink on and off. 

If this issue is not addressed immediately, it could further damage other appliances connected to it. 

To prevent any potential harm, it’s essential to inspect your power sockets regularly and change them if they are damaged or faulty. 

It is best to seek help from a certified electrician for more detailed advice. 

A blinking blue light on an ONN Monitor can indicate something wrong with your power socket, so always check and replace it if necessary.

5- Update Monitor Driver

If your ONN monitor displays a blinking blue light, this may indicate that the driver needs to be updated. 

To update the driver, you will first need to identify which make and model of monitor you have. This information can be printed on the back of your monitor or in its user manual. 

Once you have identified the make and model of your monitor, you will need to download its driver from the manufacturer’s website. 

Ensure you select the correct version for your operating system and follow all instructions carefully. 

After downloading the driver, install it on your computer following all provided instructions. 

Once installed, restart your computer and test if the blinking blue light has been resolved; if not, contact the manufacturer for further assistance.

In general, you can follow these steps:

  1. Identify the model of your ONN monitors.
  2. Visit the ONN website and go to the “Support” section
  3. Find the “Downloads” or “Drivers” page 
  4. Search for your monitor’s model update.
  5. Download the latest driver for your operating system
  6. Follow the instructions on the screen
  7. Restart your ONN monitor

It is important to keep your monitor’s driver updated to keep your display functioning properly.

 By keeping the driver up-to-date, you can be sure you receive all the latest features and security updates available for your monitor. 

This will help keep your monitor working as smoothly and safely as possible.

6- Malfunctioning Capacitors

The blue blinking light on an ONN monitor usually indicates a malfunctioning capacitor. 

Capacitors store energy and act as a buffer for the electrical current, ensuring that any excess current is returned to the power source. 

When the capacitors are not functioning correctly, they can cause the light to blink blue, indicating an issue with the monitor’s power supply. 

To fix this issue, the capacitors need to be replaced.

Fortunately, replacing a capacitor is a relatively straightforward process. First, turn off the monitor and unplug it from the power source. 

Then open up the case of the monitor to access the circuitry within. Locate the faulty capacitor, which can usually be identified by its swollen or bulging shape. 

Then, remove the capacitor and replace it with a new one of the same size and rating. 

Once the new capacitor is in place, reassemble the monitor and plug it back into the power source. 

The blue light should no longer be blinking, indicating that the issue has been resolved. 

If the light continues to blink blue after replacing the capacitor, it could mean that other components within the monitor’s circuitry are malfunctioning.

7- Factory Reset ONN Monitor

A factory reset of an ONN Monitor can also solve the problem if your monitor has any performance issues. 

For example, blinking blue light often means something is not configured correctly or has a hardware issue. 

The recommended first step to try and fix this issue is usually to do a factory reset on the monitor. 

This will erase all current settings from the device and return it to its original state so you can start troubleshooting again with the correct settings.

Nordic offers several ways to start over: Unplug all connected cables from the monitor before performing a power shutoff for 10-20 seconds. 

This should return your device to its original configuration state before troubleshooting begins with the correct settings.

It is essential to be aware that a factory reset will eliminate any adjustments or customizations you have made with the monitor, so keep this in mind before getting started. 

Once you are finished, the blue light flashing should be resolved, and your device should function correctly again.
