Our assigned solution procedures are effective enough to break down the blinking blue light on the monitor. So don’t miss a single word from this guide.

1. Faulty Power Supply

If your monitor is blinking blue light, be sure there is a problem with the power supply. When there is an interruption in fluent electrical supply through the monitor, it starts malfunctioning, including a flashing light.

Now, let’s see what possible causes for faulty power supply are:

  • Defective power cable
  • Defective power strip
  • Worn out wires
  • Faulty circuit breaker
  • Bad power supply board
  • Electromagnetic issue by other hardware
  • Non-working wall outlet


  • Check out the connectors of your monitor. If it is connected to a power strip, make sure it is well working. Replace the strip if there are any damages.
  • Sometimes, connecting electrical hardware to one power strip causes an electromagnetic issue, and that leads to the blinking problem. Remove all the hardware from one strip except your monitor.
  • Check out the wall outlet if the monitor is plugged directly into it. Connect your monitor to a different outlet
  • Then, look through all visible wires. Repair cracked or damaged ones.
  • Contact a technician in the case of a faulty circuit breaker.

2. Blown Capacitors

It seems to be the root cause behind this issue in the monitor. This happens because of overheating the monitor. When there is heat build-up in the monitor case, the inside capacitor may be blown out. 

The monitor will fail to run properly if the capacitors on the power supply are blown out. Then, it will not display correctly and flash blue light. So, it is time to check out the inside capacitor and replace the blown capacitors.


  • Turn off your monitor and disconnect it from the power supply.
  • Now, unscrew all the attached screws from the back panel and remove the plastic back of the monitor.
  • After removing the back, remove the power unit as well. Unplug all the cable that connects the power unit to the supply power board.
  • Now, identify the bad capacitor and remove the old capacitors using a soldering iron.
  • Then, solder the new capacitor in that place.
  • Reassemble the complete unit the same as you remove out.
  • Connect the back panel and turn on your monitor.
  • If all that seems hard to you, contact a technician.
