HP Omen 25L is not displaying anything when turned on.

HP Omen 25L is not displaying anything. I've tried connecting it to another monitor which works using a different HDMI cable that I also know works but still nothing. The PC was working fine yesterday but now it's no displaying anything when powered on.

Hi @Weynir,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you're having a frustrating issue with your HP Omen 25L. Here are some troubleshooting steps you can try.

Check Power Connections: Ensure that all power cables are securely connected to your PC and monitor. Sometimes a loose connection can cause display issues.

Check Monitor Input Source: Verify that the monitor is set to the correct input source (HDMI, DisplayPort, etc.).

Inspect Cable and Ports: Although you've tried different cables and monitors, double-check for any visible damage or dust in the ports. Sometimes cleaning the ports gently can help.

Reset Connections: Disconnect all cables from the PC (power, monitor, etc.), wait for a minute, and then reconnect everything.

Perform a Hard Reset:

• Power down your PC completely.
• Disconnect the power cable.
• Hold down the power button for about 10-15 seconds to discharge any residual power.
• Reconnect the power cable and try turning it on again.

Check for Beep Codes: Listen for any beep codes when you power on the PC. These codes can indicate hardware issues.

Reseat Components: If you're comfortable doing so, open the PC case and reseat the RAM, GPU, and any other removable components. This can resolve issues caused by loose connections.

Test with Minimal Hardware: If reseating components doesn't help, try booting the PC with minimal hardware (e.g., only one stick of RAM and no additional peripherals) to see if it can display anything.

Check for External Issues: Ensure there are no external issues like a faulty power supply or other components that might be causing the problem.

Check GPU Seating: If your PC has a dedicated graphics card, ensure it's properly seated in its slot and that any power connectors to the GPU are securely connected.

I hope this helps.

Take care and have a good day.
