Getting Rid of a TV Red Line

It doesn’t matter that the red line on your TV screen is not taking up much space. It still seems to be the only thing you can see. In fact, you’ve been watching it get in the way of your favorite series for 15 minutes now. And is it just me or is it…moving? Oh, no wait. You’ve just been staring at it for so long it’s making you cross-eyed!

Having a red line on your TV screen is nothing but irritating. So, let’s jump right into what you can do to eliminate the frustration for good. Coming up are 5 fixes for a line across an LCD screen. Take a look!

#1 Wait a Few Minutes for the Burn-in to Disappear

The line on your LCD TV could be what you call image burn-in. These are two types of burn-in that could happen to your screen.

  • Image persistence. This is temporary, it should go away after just a few minutes of viewing.
  • Image retention. This is permanent and will only go away if you send the television to be repaired professionally.

Let’s talk about image persistence. Image persistence is when phosphors leave behind traces of images on your TV screen. Some can appear as horizontal or vertical lines. This occurs when phosphors become too bright.

If the burn-in on your screen is due to image persistence you should do the following

  1. Wait for a few minutes. The red line should disappear on its own. You should note that the burn-in could return if the phosphors become too hot again.
  2. Test the TV screen. If the line doesn’t disappear, reevaluate it. It could be image retention. In which case, it will not disappear on its own and you will need to call a technician. If it doesn’t disappear, you can also try moving on to some of the other fixes in this article.

#2 Try Changing the Channel

A red line 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 will need to contact your service provider. You can rest assured that your TV is not at fault. (Now that’s a relief!)

Here’s how you can check if the broadcast signal source is the issue when watching cable or satellite TV.

  1. If you are watching TV via cable or a satellite, change the channel. If you have IPTV, change the channel to that service.
  2. If the red line goes away when you look at other channels, there is a problem with the broadcast signal source. You should contact your service provider for them to fix the problem.

Here’s how you can check if the broadcast signal source is the issue when using an IPTV (Internet protocol television).

  1. If you are watching TV via IPTV (ie not through cable or satellite) change the channel to cable or satellite TV
  2. If the red line goes away when you switch, there is a problem with the broadcast signal source. You should contact your service provider for them to fix the problem.

#3 Replace the HDMI Cable

Your television may also display a red line due to a connection issue. This issue could be between your TV and other devices that you have connected to it. These could include any of the following.

  • DVD player
  • BluRay player
  • Xbox
  • AppleTV
  • Playstation

Is your TV connected to any of the above devices or a different device via a HDMI cable? Then take a look at the upcoming steps that could help you remove the red line on the screen.

  1. Disconnect the HDMI cable then insert it again. Ensure that both ends of the cable are securely in their sockets.
  2. Check the TV screen. If the line still appears, move on to step 3.
  3. Disconnect the HDMI cable
  4. Replace the HDMI cable with a new one
  5. Reconnect the HDMI cable
  6. Check the TV screen. If the red line still appears, move on to the other fixes in this article.

What can you do if you cannot find the reset option on your TV? Not to worry, there is another way you can go about rebooting it without going through the TV’s menu.

Here’s what you can do.

  1. Turn off the TV using the remote control
  2. Unplug the TV from the mains. Keep it unplugged for 2 minutes.
  3. Plug the TV back in at the mains

#5 Get a Technician to Repair the PDP

If you have tried the other fixes in this article and have not had any success, you may have a hardware issue. Your LCD display panel (PDP) may be faulty. If your PDP is faulty, it may make the images on the screen 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 PDP 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 TV could invalidate your warranty.

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

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