Loose or Damaged Cable
The most common cause of a blinking blue light on a Samsung monitor is loose or damaged cables. The monitor power cable can eventually deteriorate with time, preventing it from properly connecting to the monitor.
Apart from a damaged power cord, other causes of the blue light blinking include a loose connection between the monitor cable and the computer or monitor itself. Occasionally, this happens when the cable is damaged or not properly connected. 
You can resolve this issue by checking all cables and ensuring they are securely connected to both the monitor and the computer. You should replace damaged cables with new ones.
It is important to note that damaged or loose cables can also cause other issues with the monitor, such as distorted images or no display at all. Therefore, it is crucial to check and ensure that all cables are correctly connected and tightly connected in order to prevent any issues.
Outdated Driver
Outdated device drivers may also result in a blinking blue light on your Samsung monitor. In the event your monitor drivers are out of date, you can experience issues with your Samsung monitor display, resulting in the flashing blue light.
In order to address this issue, make sure your computer’s device drivers are up-to-date. By visiting the manufacturer’s website, you can download the latest monitor drivers. In addition, you can use driver update software like IObit Driver Booster, AVG Driver Updater, Driverfix, etc to automatically detect and update outdated drivers on your PC or laptop.
Keeping your monitor or other hardware components up to date is essential to prevent issues such as poor performance or malfunctions. The best way to ensure that your computer and monitor operate smoothly and reliably is to regularly update all device drivers.
Failure of a Power Source
A defective power source can exacerbate various problems with electronic devices, including monitors. If your Samsung computer monitor blinking blue light continuously, it could be due to power source issues.
So, make sure the power outlet works properly. You can test it by plugging in another device or appliance. If the socket is not functioning, try plugging in the device to a different socket.
Also, make sure the cord does not have any signs of damage or fraying, as a damaged cord can cause electrical shorts.
When a power source overheats, it can be a sign of a defective one. Check if the power supply feels hot when you touch it. In case the power supply becomes too hot, you may have a faulty or malfunctioning power supply.
Testing the power supply’s voltage and amperage with a power supply tester will help you make sure that it is working properly. Additionally, it can be used to determine whether the power supply is short-circuited or has other problems.
It is important to ensure your devices are protected against power source issues, by using surge protectors, properly grounding power lines, and ensuring proper ventilation and cooling.
