Fix using the pressure method (hands-on)
Applying pressure to your screen may seem slightly elementary — and futile — but it has been known to do the trick fixing dead or stuck pixels. However, it’s also a method that risks furthering the problem and creating more dead pixels. Apply the pressure method sparingly if possible, whether trying to fix a dead or stuck pixel on your 13-inch laptop screen, iPhone or other device.
Step 1: Locate the questionable pixel — If you don’t know where the dead or stuck pixel is already, locate it and make a mental note of its location.
Step 2: Choose an object — There isn’t one specific object required for the pressure method. Select an object with a blunt, narrow end such as the tip of a pencil eraser, a Sharpie cap or a PDA stylus. You were to exert pressure on a limited area.
Step 3: Wrap the object — For further protection, wrap the narrow tip of the object from Step 1 in a damp, scratch-free cloth. Shy away from anything that could potentially damage or scratch your screen.
Step 4: Turn the screen off — Turn the screen off before continuing.
Step 5: Apply pressure — Gently apply pressure to the troublesome area for 5-to-10 seconds using the wrapped tip. Do so several times, but try to apply pressure solely to the area where the dead or stuck pixel is located. The goal here is to essentially adjust the pixel in the panel substrate back into proper alignment. For this reason, it may be more effective with stuck pixels than dead pixels.
Step 6: Check the results — When finished, turn the screen back on and try to locate the dead or stuck pixel in he same manner as Step 1. Check to see if the questionable pixel has returned to normal, and if it hasn’t, choose an alternative method.
