How to Fix Dead Pixels
Quick answer
Stuck pixels (colored dots — red, green, blue, white) can sometimes be fixed using rapid color cycling. Truly dead pixels (permanently black, transistor failed off) cannot be repaired by any software or pressure method and require a display replacement or warranty claim. Before trying any fix, confirm which type you have — run the color test and check whether the dot is black (dead) or colored (stuck).
The 6 Fix Methods at a Glance
| Method | Works on | Risk |
|---|---|---|
1. Pixel-Cycling Software (Fastest, No Download) Best first step | Stuck pixels on all display types | None |
2. JScreenFix and Alternative Tools Established method | Stuck pixels — LCD and some OLED | None |
3. Pressure Method LCD monitors only | Stuck pixels on thick LCD panel displays (monitors) | Medium — can cause pressure marks if done incorrectly |
4. Dead Pixel Fix Videos Convenient fallback | Stuck pixels on any screen with a browser or video player | None |
5. DaVinci Resolve / After Effects (For Video Editors) Post-production only | Dead pixels in camera sensor footage — not display hardware | None |
6. Nintendo 3DS Specific Fix Device-specific | Stuck pixels on 3DS LCD screens | Low if done correctly |
Method 1: Pixel-Cycling Software (Recommended First Step)
The most accessible and risk-free method is a browser-based pixel-cycling tool that rapidly flashes colors over the stuck pixel at ~60Hz. The principle: the transistor controlling a stuck pixel is locked in the on state. By repeatedly and rapidly toggling the intended color output, you apply an alternating voltage signal across the transistor that can break it out of its stuck state — similar to restarting a frozen circuit.
Our stuck pixel fix tool runs directly in your browser with no download. Position the draggable repair zone over the affected pixel and run it for 10–20 minutes at full screen brightness. If the pixel has not recovered after two 20-minute sessions, it is unlikely to respond to this method.

Method 2: JScreenFix and Alternative Tools
JScreenFix is one of the oldest and best-known browser-based stuck pixel fixers — it uses a small flashing square positioned over the defective pixel and runs in your browser for up to 30 minutes. It works on the same principle as Method 1 and has a long track record in the display repair community.
The main limitation of JScreenFix is that the repair zone is small and fixed — it is harder to position precisely over a specific pixel, and it does not offer full-screen treatment for OLED burn-in or widespread stuck pixels. It also depends on Flash in older versions, which is no longer supported. Modern alternatives including our tool use pure HTML5 Canvas or requestAnimationFrame for consistent 60Hz cycling. See our JScreenFix alternatives guide for a full comparison.
Method 3: The Pressure Method (LCD Monitors Only)
The pressure method works by physically manipulating the liquid crystal cell — applying gentle fingertip pressure can realign a displaced liquid crystal and restore pixel function. It only works on LCD panels (monitors, older laptops, budget phones) because it relies on the liquid crystal cell mechanics. It does not work on OLED panels, which have no liquid crystal layer to manipulate.
- 1Power off the display completely.
- 2Fold a microfibre cloth into a small pad — never use a pen, stylus, or fingernail.
- 3Apply gentle, even pressure directly over the stuck pixel for 20–30 seconds.
- 4While maintaining pressure, power the display back on.
- 5Release pressure and check whether the pixel has recovered.
- 6Repeat once if unsuccessful. If the pixel has not responded after two attempts, stop.
Method 4: Dead Pixel Fix Videos
YouTube has several "dead pixel fix" videos — full-screen sequences of rapidly flashing colors designed to stimulate stuck pixels. They use the same principle as dedicated cycling tools and are completely safe to try. Search for "stuck pixel fix video" or "dead pixel repair video" and play the video full screen with the pixel visible on screen.
The practical limitation is precision and frequency. Browser-based tools like Method 1 run at your display's native refresh rate (60–240Hz) and allow you to position the treatment zone over a specific pixel. YouTube videos are compressed, capped at 60fps, and deliver the stimulus to your whole screen rather than a targeted area. They are a convenient fallback when a dedicated tool is not available, but a purpose-built tool is more effective.
Method 5: DaVinci Resolve and After Effects (For Video Editors)
If you are a videographer or video editor, you may have noticed a fixed colored dot appearing in all your footage. This is a dead pixel on your camera sensor — not on your monitor. The camera sensor has its own pixel grid, and a failed sensor pixel shows up as a fixed dot in every frame you shoot.
DaVinci Resolve has a built-in Dead Pixel Fixer effect in the Color module. Add it as a node, then manually mark the pixel location — Resolve replaces the dead pixel in every frame with an interpolation from surrounding pixels. In After Effects, use the Clone Stamp tool or a third-party plugin like RSMB to paint out the defect per frame. These tools fix the pixel in your recorded footage; they have no effect on a dead pixel in your monitor display.
Some cameras also have a built-in pixel remapping function (Sony calls it “Pixel Mapping”; Canon calls it “Clean Manually”) that can remap a dead sensor pixel in firmware. Check your camera manual before going straight to post-production.
Method 6: Nintendo 3DS Dead Pixel Fix
The Nintendo 3DS, 3DS XL, and 2DS all use standard TN LCD panels. Dead and stuck pixels occur on 3DS screens with the same causes as any other LCD: manufacturing defects and physical damage from drops.
For stuck pixels on a 3DS, the same methods apply. Load a solid color image (use a homebrew test app or simply set a background) to confirm the pixel location and type. For the cycling method, open a rapidly-flashing video or use the 3DS browser. For the pressure method, power off the 3DS, apply gentle cloth pressure to the stuck pixel area on the screen, power back on while maintaining pressure, then release. The 3DS casing provides a firmer backing than a phone, making the pressure method somewhat more practical here than on thin smartphones.
Nintendo offers a repair service for 3DS screens. A single dead pixel on a 3DS in warranty is worth reporting — Nintendo support has been known to replace units for display defects on a case-by-case basis.
What Won't Work — Methods to Avoid
Heat gun or hairdryer
Applying heat to a display does not fix transistor failures and will cause permanent heat damage to the panel, backlight, or adhesive layers. Do not do this.
"Pixel massage" apps that claim to fix dead pixels with software
Software cannot toggle a transistor that is electrically dead. Apps that claim to fix dead pixels (as opposed to stuck pixels) are misleading. Cycling tools work on stuck pixels only.
Tapping or striking the display
Physical impact can crack the pixel layer and create more dead pixels. Tapping is not the same as the controlled pressure of Method 3 and should be avoided.
Leaving a static white image on screen overnight
This is an old, outdated advice that can cause burn-in on OLED panels. It has no mechanism to fix a stuck pixel and may make your display worse.
When to Stop Fixing and Claim Warranty
If the pixel has not responded after two full 20-minute cycling sessions, it is unlikely to recover. At this point — especially if the display is within its warranty period — stop trying physical methods and file a warranty claim instead. Physical intervention (pressure marks, scratches, heat) gives the manufacturer grounds to reject a claim as user-inflicted damage.
Document the defect on a white background photograph before attempting any fix, so you have clean evidence of the original defect. See our dead pixel warranty guide for how to approach each major manufacturer — thresholds, what to say, and what to send.
