Try a solid state solu­tion like Pix­el­Tuneup (see Sources and Cita­tions). These devices pro­duce spe­cially tuned video sig­nals that elim­i­nate stuck pix­els while enhanc­ing pic­ture qual­ity, color, and con­

trast. Also works on tele­vi­sions, includ­ingLCD, LED, plasma, or CRT.

1. Turn off the mon­i­tor.
2. Plug in and turn on Pix­el­Tuneup, then turn on the mon­i­tor.
3. Wait 20 min­utes.
4. Turn off and unplug Pix­el­Tuneup.

Stuck pix­els and other IR will be gone, and color/contrast will be improved.

Pres­sure Method

1. Turn off your computer’s mon­i­tor.
2. Get your­self a damp wash­cloth, so that you don’t scratch your screen.
3. Take a house­hold pen, pen­cil, screw­driver, or some other sort of instru­ment with a focused, but rel­a­tively dull, point. A very good tool would be a PDA stylus.
4. Fold the wash­cloth to make sure you don’t acci­den­tally punc­ture it and scratch the screen.
5. Apply pres­sure through the folded wash­cloth with the instru­ment to exactly where the stuck pixel is. Try not to put pres­sure any­where else, as this may make more stuck pixels.
6. While apply­ing pres­sure, turn on your com­puter and screen.
7. Remove pres­sure and the stuck pixel should be gone. This works as the liq­uid in the liq­uid crys­tal has not spread into each lit­tle pixel. This liq­uid is used with the back­light on your mon­i­tor, allow­ing dif­fer­ent amounts of light through, which cre­ates the dif­fer­ent colors.

Tap­ping Method

1. Turn on the com­puter and LCD screen.
2. Dis­play a black image, which will show the stuck pixel very clearly against the back­ground. (It is very impor­tant that you are show­ing a black image and not just a blank sig­nal, as you need the back­light­ing of the LCD to be illu­mi­nat­ing the back of the panel).
3. Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this.
4. Use the rounded end of the pen to gen­tly tap where the stuck pixel is – not too hard to start with, just enough to see a quick white glow under the point of con­tact. If you didn’t see a white glow, then you didn’t tap hard enough, so use just slightly more pres­sure this time.
5. Start tap­ping gen­tly. Increase the pres­sure on the taps grad­u­ally for 5–10 taps until the pixel rights itself.
6. Dis­play a white image (an empty text doc­u­ment, or send­ing your browser to about:blank and going to fullscreen with F11 is good for this) to ver­ify that you haven’t acci­den­tally caused more dam­age than you fixed.

Heat Method

This method is use­ful if large areas are dis­col­ored or even black. Works best with lap­tops, but may work with sep­a­rate mon­i­tors, too. By using this method, you are expos­ing your com­puter to the risk of dam­ag­ing the proces­sor and/or other com­po­nents by over­heat­ing. If you do this, you should be will­ing to accept the loss of your com­puter (for lap­tops), or mon­i­tor (for stand­alone screens). You should backup your data before try­ing this method. In par­tic­u­larly bad cases of dam­age, the effect may not work com­pletely, or the fix may not be permanent.

1. Turn on the com­puter.
2. Make sure it is plugged into wall power.
3. Go to your power set­tings in the con­trol panel and set the com­puter not to go to sleep or standby mode.
4. Place the lap­top in a partially-closed desk drawer or some­where that is not well-ventilated.
5. Close the lap­top lid almost com­pletely, but don’t let it close fully – This will keep the lap­top screen turned on indef­i­nitely. You may take a small paper pam­phlet or some­thing soft and place it on the key­board to pre­vent grav­ity from clos­ing the lid.
6. Let the com­puter sit for sev­eral hours or even days in this con­di­tion. You may check on it as fre­quently as you like. The heat gen­er­ated will cause the liq­uid crys­tal to flow more eas­ily into the areas that were not for­merly filled.
