Sceptre Monitor Blinking Blue Light – Causes and Solutions

You can stop blinking blue lights on monitors in our assigned solution procedures. Make sure you read this guide all the way through.

Defective Power Supply

Check the power supply if your monitor is blinking blue light. Any interruption in the electrical supply will cause the monitor to malfunction, including flashing lights. A faulty power cable or power strip, Broken wires, a Defective circuit breaker, a Damaged power supply board, Other hardware causing electromagnetic interference, and an Inoperative wall outlet are the possible causes of a defective power supply.

How to Fix Defective Power Supply?

  • Inspect the monitor’s connectors. If the monitor is connected to a power strip, make sure it is working properly. Replace the power strip if damaged.
  • An electromagnetic issue can occur when electrical hardware is connected to one power strip, causing the blinking. Disconnect all your peripherals, except your monitor, from one strip.
  • Check the outlet if the monitor is directly plugged into the wall outlet. Move the monitor to another outlet.
  • Then inspect all the visible wires. Repair any broken or damaged wires.
  • Contact a technician if the circuit breaker is faulty.

Monitor’s Refresh Rate

Changing a monitor’s refresh rate can sometimes fix the blinking. When the refreshing rate is too low, flickering occurs because there are not enough updates per second. The smooth display can only be maintained with a higher refresh rate. If you are still experiencing blinking issues after replacing the bad capacitor or changing the power supply, check your monitor’s refresh rate. Wondering how to do this? You can change your monitor’s refresh rate by following these steps:

How to Fix Monitor’s Refresh Rate?

  • Start by right-clicking the Start button.
  • From the drop-down menu, click the Control Panel.
  • Next, choose display. Click on Change Display Settings on the left-hand side of the window.
  • Select Advanced Settings on the bottom right of your monitor’s window.
  • Now click the Monitor tab. You will find your monitor’s refresh rate on the refresh rate tab. You will have to change it if it is too low.
  • Click on the drop-down menu. Then set a higher refresh rate to see if the blinking stops.
  • If it doesn’t, we have other solutions available.

Blown Capacitors

It appears to be the main cause behind this monitor problem. This happens when the monitor is overheated. The inside capacitor of the monitor can blow out when overheating occurs inside the case. If the capacitors on the power supply blow out, the monitor won’t work correctly. This will result in the monitor not working properly and flashing blue. In this case, check the inside capacitors and replace those blown.

How to Fix Blown Capacitors?

  • Disconnect your monitor from its power supply and turn it off.
  • Remove the plastic back of the monitor by unscrewing all the screws attached to the back panel.
  • Once you’ve removed the back, disconnect the power cable. Disconnect the cables that connect the power board to the power unit.
  • Then, you must determine which capacitor is damaged and remove the old capacitors using a soldering iron.
  • Replace the old capacitor with the new one.
  • Reassemble the entire unit the same way you took it apart.
  • Turn on your monitor after connecting the back panel.
  • If that seems challenging, contact an expert.

Power Reset The Monitor

Resetting your monitors will be your next step if all the steps above cannot fix the blinking issue. Resetting the monitor usually fixes your problem. Here are the instructions to reset the monitor power supply without wasting any time:

  • Shut down your monitor. Disconnect your monitor from the power strip.
  • Then, remove the cord from the monitor receptacle.
  • Unplug the cord at the back of the monitor.
  • For 15 to 20 seconds, press the power button.
  • Plug the HDMI and VGA cables into their respective ports.
