Moving dead pixel

[ISHAN20]

In my laptop recently I have seen some dead pixel but slowly they are spreading. When I press it by finger it moves to new place and old dead pixel glows

Hi @ISHAN20,

Welcome to HP Support Community.

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

The behavior you’re describing, where dead pixels seem to move and glow when pressed, is unusual and may indicate a problem with your laptop's LCD screen.

1. Stuck Pixels: Pixels that appear "dead" but are actually stuck on a specific color or brightness level.
2. Pressure Damage: Physical pressure on the screen could disrupt the liquid crystals, causing issues with pixel functionality.
3. Debris or Air Bubbles: If the dead pixels "move" when pressed, it might suggest a layer inside the screen has a defect, like trapped debris or air bubbles.

Troubleshooting Steps:

Pixel Repair Tools:

• Use software tools like JScreenFix or other pixel repair applications to attempt to revive stuck pixels. These rapidly flash colors over the affected area to stimulate the pixels.

Gentle Massage:

• Power off the laptop.
• Use a microfiber cloth to gently massage the area where the dead pixels are located. Apply light pressure in a circular motion.

Check Display Connections:

• If you're comfortable, reseat the display cable inside the laptop. A loose connection can cause anomalies like dead pixels spreading.

Display Diagnostics:

• Run the built-in HP diagnostics (press F2 during boot to access the hardware diagnostics). This will help confirm if the issue is with the screen or another component.

External Display Test:

• Connect your laptop to an external monitor. If the issue doesn’t appear on the external display, it confirms a problem with your laptop’s screen.

I hope this helps.

Take care and have a good day.
