How do you fix a dead pixel screen?
Share
Fixing a dead pixel on a screen can be a bit tricky, as it depends on whether the pixel is truly "dead" or just "stuck." A dead pixel is a pixel that doesn’t display any color or light, while a stuck pixel displays a fixed color (red, green, blue, etc.) and can potentially be fixed with some techniques. Here’s how you can try to fix these issues:
1. Distinguish Between Dead Pixels and Stuck Pixels
- Dead Pixel: Completely black and doesn’t light up at all.
- Stuck Pixel: A pixel that stays on one color (usually red, green, or blue) and does not change like the rest of the screen.
2. Fixing a Stuck Pixel
If your pixel is stuck (but not dead), here are some methods that may help:
A. Pixel Fixing Software
-
What It Does: These programs rapidly change the colors of the pixels to try to “unstick” a stuck pixel by quickly cycling through colors.
-
How to Use:
- Use software like JScreenFix or Dead Pixel Tester.
- Visit the website and launch the pixel-fixing tool.
- Leave the tool running for about 10–15 minutes on the stuck pixel. The rapid flashing of colors might help the pixel return to normal.
-
Pros: Easy to use, no physical handling of the screen required.
-
Cons: Not guaranteed to work on all stuck pixels.

B. Manual Techniques
-
Gently Massage the Screen: Sometimes applying gentle pressure to the stuck pixel area can help. Use a soft cloth and press very gently on the affected area to see if it helps the pixel reset.
-
Procedure:
- Power off the device.
- Wrap your finger in a soft, clean cloth to avoid damaging the screen.
- Apply gentle pressure to the stuck pixel area (not too hard!).
- While pressing, turn the device back on to see if the pixel resets.
-
Procedure:
-
Pros: Simple, doesn’t require software.
-
Cons: Can cause damage if done incorrectly or too forcefully.
C. Use a Static Image or Video
-
What It Does: Display a solid color or an image with a variety of colors on the screen for several hours to "unstick" a pixel.
-
How to Use:
- Display a full-screen image (such as a white or black screen) for 10–30 minutes.
- You can find websites with full-screen color options or create one yourself by displaying an image with a single color.
- Alternatively, use a video with flashing colors.
- Sometimes the combination of colors flashing on the screen can get the stuck pixel to start functioning properly again.
-
Pros: Easy and free.
-
Cons: Takes time and may not always work.
3. Fixing a Dead Pixel
If the pixel is completely dead, your options are more limited.
A. Try the Same Methods as for Stuck Pixels
- Pixel Fixing Software: Sometimes dead pixels are just very stubborn stuck pixels that don’t respond to the usual techniques. Try the same software or manual techniques to see if you can get the pixel to start responding.
- Static Color Screen: Try using a full-screen white or black image for hours as it may have an effect on a dead pixel that is not completely "dead" but stuck in a non-functional state.
B. Factory Reset or Software Solutions
- On rare occasions, a dead pixel can be caused by software glitches. Try restarting the device or doing a factory reset (especially for smartphones and tablets) to rule out software issues.
C. Professional Repair
- When It’s Necessary: If the pixel remains dead and it significantly affects your viewing experience, the best option is to get the screen repaired or replaced.
-
How to Proceed:
- For smartphones: Contact the manufacturer or an authorized repair center for a potential screen replacement.
- For laptops/monitors: Check if the device is still under warranty and if a screen replacement is covered.
- Pros: If your device is under warranty, screen replacement might be free or discounted.
- Cons: This can be expensive and often not worth it if only one or two pixels are dead and don't affect overall performance.
4. Warranty or Return (If Applicable)
- If the screen has multiple dead pixels or is still under warranty, returning the product or asking for a replacement could be your best option.
- For Monitors and Laptops: Check the manufacturer’s dead pixel policy. Some companies have a policy where they will replace the device if there are a certain number of dead pixels.
- For Phones: If the device is new and has a dead pixel issue, check if it qualifies for warranty replacement.
5. Prevention Tips
- Use a Screen Protector: Using a screen protector can help prevent the buildup of pressure points that can cause stuck pixels.
- Be Gentle: Avoid pressing hard on your screen and handle it carefully to reduce the risk of damaging individual pixels.
- Avoid Extreme Conditions: Extreme temperatures or physical shocks (like dropping the device) can lead to pixel damage.
Summary
- Stuck Pixels: Try using pixel fixing software, gently massaging the area, or displaying static color images to unstick them.
- Dead Pixels: If a pixel is dead (black with no color), software fixes may not work, and you’ll likely need a replacement screen or professional repair.
- Warranty: If you have multiple dead pixels and the device is under warranty, you might be eligible for a replacement.
