How to Fix Sceptre Monitor No Signal (100% Fixes)

When a Sceptre monitor displays ‘No Signal’ or fails to turn on, it is typically due to loose or faulty cable connections, incorrect input source settings, or software issues.

But, sometimes internal components can also cause this issue.

In this article, I will walk you through why your Sceptre monitor is displaying ‘No Signal’ and entering power save mode, and what you need to do to get it working again.

Let’s move on…

The reasons why this happening!

If your Scepter monitor displays ‘no signal,’ it means the monitor isn’t receiving any information from the computer.

There are a couple of reasons for this, including:

  • Loose cables
  • Problems with the computer’s software
  • Issues with the monitor’s hardware
  • A bad connection

How to Fix This Issue

  • Check all the cable connections and attach them firmly on both sides.
  • Check the input settings on the monitor to make sure they are set correctly.
  • Switch to a different input on the monitor.
  • Power cycle both the CPU and Monitor.
  • Try a different HDMI cable.


Here are the detailed guidelines:

Step 1) Check the cable connection

The main reason for this problem is often a loose video cable connection.

In fact, 95% of experts recommend checking the video cable before trying more complex troubleshooting.

This is because the video cable’s job is to carry signals from the CPU to the monitor.

If it’s broken or not working correctly, the monitor won’t get any signal.

Take a close look at the video cable to see if there’s any visible damage. Then, make sure the cable is firmly connected on both ends and is plugged into the right input.


Step 2) Power cycle the Monitor

First, let me explain why this method works!

Most devices that use operating systems can sometimes have temporary problems with their systems. These issues can make the device act strangely even if everything else is working fine.

Since your monitor is also a device with an operating system, it might encounter similar problems that can make it unable to understand the signal coming from the CPU.

In such situations, a simple power cycle can often solve the problem.

Here’s what you can do:

  • Completely unplug both the monitor and the CPU from the power outlet.
  • Press and hold the power button on both devices for about 30 seconds.
  • After that, plug them back in.

Now, check to see if the problem is fixed. If it’s not, move on to the next step.

Step 3. Check if your monitor is malfunctioning

If power resetting doesn’t solve the issue, try connecting the monitor to a different computer to see if it works properly.

If it does, then the issue is likely with your original computer.

Otherwise, it’s likely that the problem is with the monitor itself, and you may need to contact a professional for repair or replacement.

Step 4. Problem with the source device

Did you turn on your CPU before the monitor? or is the CPU working correctly?

Though these are nonsense questions, many forget the basics.

Because the monitor will show a “No Signal” warning until it detects a reliable video signal from the computer or source, So, please make sure your computer is turned on.

If yes, check this by

  • Connecting another display with your computer.
  • Connecting the same display with another computer.

Step 5) Check your PC’s Hardware

If none of the steps mentioned work and your Sceptre monitor is still displaying “No-Signal” message, one of your computer’s internal components, such as the graphics card, may be faulty, or the RAM stick could be dusty.

In this case, checking and cleaning can both fix the issue.

Open the PC’s back case and locate the graphics card first, as it is the most likely component to cause a “no-signal” issue if it is loose or damaged. Then, check the RAM sticks. If the RAM stick is dirty or dusty, clean it.

Before you disassemble your PC, ensure that your computer is turned off. Also, unplug all cables, including the power cord, to avoid electric shock.
