Fixing stuck or dead pixels

Fixing stuck pixels

A stuck or dead pixel on your TV can be really annoying. It might show up as a small white area when the rest of the screen is dark, or it could be stuck on a single colour. So let's take a look at what you can do to fix it.

Figuring out what the problem is


There are usually two types of faulty pixel - it might just be stuck, or it could be completely dead. Here's how to figure out which one it is.

  • Pause the TV on a screen or picture that's completely black, then look for the pixel that isn't working. If it's any colour other than black, it's probably just stuck and you might be able to fix it. If you can't see the pixel against the black screen, try the next step.
  • Try pausing the TV on a screen or picture that's completely white. If the one you think is broken is still black, then it's probably dead.

Stuck pixels


Stuck pixels can often be fixed because power is still getting to the pixel, but it's just stuck on one colour. The first thing to note is that stuck pixels will often fix themselves over time - but if it doesn't there are a couple of things you can try.

  • Try leaving the TV switched off and unplugged for at least 24 hours. If the pixel has stopped working because it's been overused, leaving it switched off for a while can fix it.
  • Try screen-fixing software - if it's a stuck pixel, this type of software has a good chance of fixing it. It works by blasting the affected area with random colours to try and kick-start the pixel. You'll need to connect your TV to a computer or laptop using an HDMI lead, then go to, and click Launch JScreenFix. Then just drag the box over the affected area and leave it for at least 10 minutes.
  • If neither of these work, the last resort is to try rubbing the pixel back to life - but be aware that applying too much pressure can cause damage to other pixels. You'll need to use a damp cloth and apply gentle pressure to the stuck pixel. While you're applying the pressure, turn the TV on and hopefully, the stuck pixel will be fixed.

Dead pixels


Unfortunately, dead pixels can't be fixed so easily. If it's just a single pixel, and your TV is still under warranty, you'll need to check with the manufacturer whether the warranty would cover it. If it's no longer under warranty, we might be able to help - find out more about our expert repair service here.
