Laptop "Dead Pixels" (Stuck Green/Red/Blue Dot)
4.5
A tiny dot on the screen stays one color no matter what is being displayed.
Symptoms
- Bright dot
- Black dot
- Distracting mark
Possible Causes
- Manufacturing defect
- Transistor failure
Step-by-Step Fix
1
Run a Pixel Fixer App
Use a website that flashes colors rapidly to try and "unstick" the pixel.
2
Apply Gentle Pressure
Wrap a cloth around a pen and very gently press on the stuck pixel (use with caution).
3
Check Warranty
Most manufacturers have a "dead pixel policy" (e.g., 3+ dots required for replacement).
When to See a Technician
A "stuck" pixel (colored) can often be fixed; a "dead" pixel (black) is usually permanent.
