Unsticking Stuck LCD Pixels

Sometimes the pix­els on an LCD can become stuck, dis­play­ing only some col­ors or appear­ing com­pletely dead. These black or oddly col­ored spots are a pain in the neck but they’re not always per­ma­nent. At some point last sum­mer the Mac lap­top I was work­ing on got a stuck pixel and after scour­ing the inter­net for infor­ma­tion on how to fix such things I came across instruc­tions for fix­ing stuck pix­els on the PSP that involved play­ing a par­tic­u­lar video file, con­tain­ing RGB pulses, and mas­sag­ing the screen around the stuck pixel. The PSP tech­nique worked fan­tas­ti­cally and in a few moments my screen was free of stuck pix­els. I have a sim­i­lar prob­lem on the machine I’m using right now but this machine has no means of play­ing .mp4 files (which the PSP pixel fix­ing video is) and rather than try­ing to fig­ure out how to make it play .mp4 files, I thought I’d ImageMagick myself up a quick solu­tion. To that end, I cre­ated three ani­mated gifs that pulse at dif­fer­ent fre­quen­cies (rgb3.gif, rgb5.gif and rgb7.gif), which serve the same pur­pose as the video and are sub­stan­tially smaller in size (1.2KB vs 1.5MB). The great thing about these is they’re essen­tially plat­form inde­pen­dant and require no video codecs at all. To fix your dead pix­els, just fire up a graph­i­cal web browser, point your­self at one of the images, move the browser win­dow so that the image is under your dead pixel, mas­sage the screen a lit­tle and with luck the pixel may start work­ing again. If you don’t have any luck try one of the other fre­quen­cies and if that doesn’t work, I’m sorry.

    Well… did it work for you?

  2. 712 says:

    I have a pixel stuck on red, and unfor­tu­nately, your ani­mated gif didn’t help it. It was, how­ever, good for rav­ing to.

  3. gwax says:

    Sadly no, maybe one needs a spe­cific frequncy.

  4. Michael says:

    When you say “mas­sage”, do you mean to lit­er­ally rub your thumb on the dead pixel?

  5. Simon says:

    You are a leg­end! The first time i turned on my new note­book i dis­cov­ered a pixel per­manantly white! I had a headache from abus­ing peo­ple at Acer Support Line so i tried your lit­tle pro­gram. About ten sec­onds of strob­ing funky colours and cir­cu­lar masag­ing later and… hey presto… one fully func­tion­ing pixel. Thanks

  6. gwax says:

    Michael: Yes, but prefer­ably with a tis­sue or cloth between you and the screen; I rec­om­mend a cir­cu­lar motion.

    Simon: I’m glad that I could help; you’re welcome.

    my brand new acer 20.1″ inch TFT seems to have 2 very strange pix­els, one small red one and a big­ger brighter pur­ple.
    I’ve run some mp4 video with the same stuff as the gif image and it’s man­aged to fix the red one after just a few min­utes but the pur­ple one is still bee­ing worked on.
    it’s strange how its not vis­si­ble when there is white imagery.

  8. Tray Parker says:

    update:
    i ran the gif image, the fastest one just over the defec­tive pixel all night and it still hasn’t fixed the pixel, so im going to talk to the store i bought it from and see if they can send a new one, if not I’ll return it on my 14 days dis­tans buy­ing law that applied when buy­ing over the inter­net and phone.

  9. gwax says:

    Yeah, I’ve encoun­tered mixed suc­cess as well. I’m inclined to believe that there is more than one way that a pixel can break and that the color cycling trick only works for cer­tain types of bro­ken pixels.

    Good luck and I hope every­thing works out for you in the end.

    My Ilyama 17″ LCD came with one pixel stuck on white, and the sec­ond image and some mas­sag­ing fixed it. Now it’s came back (a cou­ple of days later) stuck on green, and the first image fixed it, I’ll have to see if it works per­ma­nently this time.

    son of a bitch it does not work it is a waste of time

  12. jplace says:

    Wow! It worked imme­di­ately for me. I’ve had that dead pixel for a cou­ple years. I ran the first GIF (3) and very lightly touched the pixel/screen and it came back instantly. Hopefully it will stay that way.

  13. dithered says:

    I just got a new LCD and it had one pixel stuck on white. Your gifs fixed it. It would go away for a bit while I was mas­sag­ing, then reap­pear, but on the third gif it went away for good (so far). Thanks!

  14. Scott Stoller says:

    I just got a thinkpad x61 with one stuck pixel. I played rgb3.gif inside mozilla for a minute while mas­sag­ing the stuck pixel. fixed!

    thanks for mak­ing these gif’s available!

    scott

  15. Zander says:

    THANKS!!! I just ordered a new mon­i­tor and thought I had a dead pixel! But it was revived with your method of mas­sag­ing the mon­i­tor while watch­ing the video and chanting.

  16. Dave says:

    Worked great in a few sec­onds for a sticky blue pixel! thx!

  17. Draenog says:

    Thanks so much. The first gif and some fairly heavy mas­sage­ing fixed my bright blue pixel.

  18. Shakey says:

    My Stuck pix­els weird, you cant see it with the blue back­ground or the red one, it only shows against a green background.

  19. gwax says:

    Shakey: That is not weird; it is often the case that only one of red, green or blue is dead. In your case, only the green pixel is dead. My gifs are about as likely to help you as any other case so I wish you the best of luck.

  20. Tiago says:

    i just touched the pixel and it disapiaed

  21. Mike says:

    DAng! I got home with my new mon­i­tor from christ­mas, and i find a pixel stuck on green!! i was so pissed, but your thing worked!! Thank you so much!

  22. LINEMAN78 says:

    Thank you!!! I just got a brand new LG 25.5″ W2600H and it had a pixel stuck green right in the mid­dle of the screen. I tried both 3 and 5 with some strong pres­sure and rub­bing and I took my fin­ger away and pop, it dis­ap­peared. You are a saint! Since newegg only takes it back if it has 8 dead pix­els I woulda been screwed.

  23. Andy Be says:

    Thanks alot mate!, bought a new Hanns G 22″ Monitor, had a stuck red pixel… used the first gif with some firm mas­sag­ing and it dis­ap­peared! =D great stuff… leg­end haha

  24. Mark says:

    Holy Shit!!! It did work! I had my doubts at first but when I rubbed the screen presto GONE! Thanks Gwax.

  25. Tilmitt says:

    I had a blue stuck pixel, but this strob­ing images and a small bit of mas­sag­ing unstuck it in only about 10 sec­onds! Thanks!

  26. Peter says:

    I’ve tried many of these but I just can’t do the mas­sage as I have a 2009 iMac which has a glass panel in front of the screen so I can’t touch the pix­els. What can I do?
    Apple have an up to 8 defec­tive pix­els for me to get it replaced and I only have 1 pixel stuck bright blue a few inches from the bot­tom of the screen.

  27. Retep says:

    Yeah… ditto peter. 2009 imac, stuck red pixel on the right. damn apple.

  28. Gumby says:

    Koolbeans, it worked! I have a new Acer 8930 lap­top with an annoy­ing red pixel

  29. adrielt says:

    hi gwax, if it’s not much trou­ble, can u upload a 640x360 ver­sion of the images? if i view it on my fone it dis­plays right smack in the cen­ter and if i stretch the image, it no longer changes the col­ors rapidly.. =(

  30. Gabriel Syme says:

    You genius. I pur­chased a brand new Dell Inspiron 1764 last week, fired it up today and bam — pixel dead cen­tre stuck on green. Rubbed the screen very gen­tly with my thumb and it flick­ered and went away. It would never have even crossed my mind to do this. Cheers!
