Fixing White Spots Appearing On A TV Screen In 4 Ways

Featured-new-tv

Are you seeing white dots on your TV screen, and you fear it’s done for?

You’re not alone – this is a common issue faced by many modern TV owners.

White spots on your TV screen are essentially dead pixels. These can be tricky to fix, but there a number of fixes we can walk you through that may do the trick.

Before we get started with this article, we need to advise you NOT to try opening up the back of your TV or doing any DIY electronic repairs. TV capacitors can hold a charge for years, and they can be lethal if not handled correctly.

Instead, read on and follow our safe troubleshooting steps below.

Troubleshooting White Dots On Your TV

#1 Try Changing the Channel

There’s a chance that white dots on your TV screen could indicate that there is a problem with the broadcast signal source, rather than with the TV itself. If this is the case, you’ll need to contact your service provider. You can rest assured that your TV is not at fault. (Now that’s a relief!)

The best way to do this is to switch to a totally different input. For example, changing from the cable box to streaming through internal smart apps.

Here’s a few steps from Austin, our TV Expert:

  1. Change the channel.
    •  White spots go away? It’s the channel.
    •  White spots persist? Next step.
  2. Change to a different source (i.e. from Cable to HDMI)
    • Spots go away? Issue is either with the source device or HDMI cable.
    • Persists? Next step.
  3. If using a smart TV, switch to an app using the original TV remote, not an external device (i.e. roku, fireTV, AppleTV, etc.).
    •  White spots go away? It may be the mainboard on the TV. Try changing the HDMI cables, and remove any “middle-man” devices such as AV receivers or sound bars.
    •  Persists? Either the panel or the T-Con board, both are usually sold as the panel itself.
  4.  If you change the cables and remove “middle-man” devices and it is still there, contact a technician. Mainboards are costly, but panels are often more than a new comparable TV.
  5. Some manufacturers have built in panel tests, such as LG, Samsung, and Sony.

#2 Replace the HDMI Cable

If, using the steps above, you think it’s the HDMI cable – you may just need a new one. OR the issue may be between the TV and what it’s connected to (Playstation, Apple TV, etc).

If you can, swap out the HDMI cable for a new one, or one you know works, and see if that solves the issue. If it doesn’t, but the spots are only coming from one device, then that may be the culprit.

#3 Restart / Reset the TV

As with any type of electronic system, a reset can often fix a lot of issues.

The old magic of “turning it off then on again”.

First, try turning it off then unplugging the TV. Give it a couple of minutes, and plug it back in again.

Didn’t work? Then let’s try a software reset.

This will be different depending on your TV model and brand, but here’s the general steps:

  1. Press the “Menu” button
  2. Select “Settings”
  3. In the settings tab, look for the “Reset” option. This could also appear as “Factory Settings”
  4. Follow the instructions on the TV screen to reset it
  5. Check the TV display. If the white spots still appear, move on to the other fixes in this article.

#4 Get a Technician to Repair the Screen

If you have tried the other fixes in this article and have not had any success, you may have a hardware issue. Your display panel may be faulty. If your screen is faulty, it may make images appear incorrectly. They could display in any of the following ways.

  • Blurry images or picture
  • Discolored images or picture
  • Misshapen images or picture
  • Horizontal or vertical lines on the screen
  • Dots over the screen

When your display panel starts to play up, there’s not much you can do about it without taking the TV apart and repairing it. Perhaps you’re up for the challenge! But unfortunately, taking the back off of your can be extremely dangerous – so we strongly advise not to go meddling with it. Plus, it could invalidate your warranty.

If your panel is in need of repair you should do one of the following

  • Call your TV manufacturer
  • Take the TV to a professional repair shop

Conclusion

Seeing white dots on your TV screen is distracting and frustrating, and trying to get rid of them on your own might seem daunting without the right instructions. I hope this article’s clear, easy-to-follow steps have been of assistance to you.
