What do you do when your LG 4K monitor won’t turn on?? Will you go to a mechanic straight away or do some troubleshooting first?

The answer is simple. You will check the basic connectivity, and try a few tricks without damaging the monitor or voiding the warranty.

In this article, I have talked about all those troubleshooting steps and tricks so that no one has to pay for easily solvable problems.

LG 4k Monitor Won’t Turn On, What Should I Do?

When you press the remote and see that your LG 4K monitor is not turning on, it must feel frustrating.

I have seen lots of similar complaints in various forums, and the solution in most cases is very simple.

Most of the time, the connection is loose. Doing deep research on the topic, I have found several other issues or reasons for this problem.

First, I am going to tell you the troubleshooting steps described in an official LG video tutorial.

Step 1: The very first step is to make sure that your 4K LG monitor has the LED indicator lit. Power on the switches, and check the indicator. Some models may not have a visible indicator on the front.

Step 2: If the plug of the monitor is connected to a multiplug, check whether the multi-plug is functional by powering other appliances. LG recommends plugging the monitor connector directly into the wall outlet.

Step 3: Sometimes, the plug gets loose while cleaning the area or playing with children. You have to make sure that the plug is fully inside. Apply a little bit of force to make sure.

Step 4: After that, check whether the other end of the plug is properly connected to the monitor. If your monitor doesn’t have a detachable power cord, you can go to the next step.

Step 5: In some cases, unplugging, waiting for 10 seconds, and plugging it back again solves this issue.

Step 6: Once you have solved the power issue, you will have to focus on the signal. What I mean is that one has to take care of the monitor showing no signal message. 

Step 7: Lastly, seeing no improvement even after applying all those troubleshooting methods may lead to contacting customer care support. You can claim the warranty or take the monitor to a nearby repair center if the warranty period is expired.  

Pro Tip: Another explanation for not getting the solution after applying the above steps may indicate that the power cord or cable is faulty. Try another power cable and see whether it solves the problem.

Once you have confirmed that the LG monitor not powering on the issue is solved, you can move on to the PC part for further inspection.

Here, check the VGA or HDMI port and cable. Any problem in this part will result in a ‘No Signal’ message on the screen.

Sometimes, not installing the right driver and not connecting the monitor’s connection to its respective port can lead to the same problem.

Bottom Line

This problem of the LG 4k monitor won’t turn on is easily solvable most of the time.

Sometimes, you may not see any results even after applying all those methods mentioned above.

In that case, spend no more time or try any destructive mods, and take the monitor straight to a mechanic or service center.
