Sceptre Monitor no Signal/Not Turning on (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.

However, sometimes internal components can also cause this issue.

In this article, I will break down 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 dive into it…

Why Sceptre Monitor display No Signal

Your Sceptre monitor displays ‘no signal’ because it’s not receiving any signal from the computer.

Several factors can cause this issue, such as loose cables, internal software glitches, hardware faults, or a faulty connection.

How to fix the Sceptre monitor No Signal

  • Check all the cable connections and attach them firmly on both sides.
  • Switch to a different input on the monitor.
  • Power cycle both the CPU and Monitor.

Step 1: Check the cable connection

A loose video cable connection is the primary reason that can cause this issue. In fact, 95% of electricians suggest checking the video cable before performing other complicated troubleshooting.

This is because the video cable is responsible for carrying signals from the CPU to the monitor, and if it’s damaged or malfunctioning in any way, the monitor will not receive any signal.

Carefully inspect the video cable for any visual damage. Then, ensure the cable is securely connected to both sides and is plugged into the correct input.

Step 2. Power cycle the Monitor

First, let me tell you why this method is effective!

Almost all types of OS-operated devices experience temporary system glitches, which can cause the device to behave strangely even if all other parts are functioning properly.

Since your monitor is also an OS-operated device, it may experience similar glitches that can hinder its performance and prevent it from decoding the signal sent by the CPU.

In such cases, a simple power cycle can help solve the issue.

Here’s how:

  • Disconnect both the monitor and CPU from the power outlet completely.
  • Press and hold the power button on both devices for about 30 seconds.
  • Once done, replug them back in.

Now check whether the problem has been fixed. If not, proceed 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.

  • Verify that the monitor’s power button is in the “On” position.
    Try a different power cable or adapter if available.
  • Check the cable connection between the monitor and the computer or other video source.
  • Adjust the display settings on your computer or video source to ensure compatibility with the monitor.
