You can easily solve such issues without any expert supervision. 

1. TV Not Connecting to Wi-Fi

Losing Wi-Fi connectivity is the most commonly faced issue among LG TV users.

This problem can occur due to several reasons, such as a temporary bug, router issues, or weak signals. 

Before doing anything with your TV, first, try connecting any other Wi-Fi to the TV. This will help you figure out whether it is the router issue or something is wrong with your TV.

If the TV gets connected to some other Wi-Fi network, then something must have gone bad with the TV.

You can follow these steps to troubleshoot the problem.

  • Restart the TV by disconnecting the power supply and then reconnecting it after a few minutes. 
  • Power off any nearby electronic devices like a microwave oven. These devices may be causing interference.
  • If there is an issue with the router, try restarting the router and then connecting the network.
  • Make sure that your TV has updated software as that can also be the reason behind it.

Are you still unable to fix this issue? Here is our complete guide on LG TV Not connecting to Wi-Fi.

2. LG TV Screen Problems

If you see your LG TV turning on and off on its own or the screen going completely blank, the problem might be occurring because of the faulty capacitors on the board. Apart from this, it can also be due to less power input. 

To troubleshoot this issue, you can follow the instructions listed below.

  • Check your power inputs and make sure your TV cables are properly connected.
  • Unplug the main power cord and plug it back in after about half a minute. 
  • If this does not work, then there is a possibility that the issue is with the capacitor or any other internal component. For this, you might need assistance from a highly-skilled technician. 

3. LG TV Not Responding To Remote

If your LG TV does not respond to the remote, you can try the following steps to make it work.

Whether you have a magic remote or a standard remote, you can easily solve this issue.

  • Firstly if none of the buttons work, try replacing the batteries. Make sure that you place them properly, matching the + and – signs. Also, do not mix the old with the new ones.
  • Make sure that no obstructions are blocking the IR signals.
  • If you have a magic remote, you can try unregistering and re-registering the magic remote if only some of the buttons are working. 

4. LG TV No Sound

You might face this issue with your LG TV in that there is no sound output from the speaker or not having no audio signals.

This problem is known to occur due to the failure of fuses

You can troubleshoot it by rebooting your TV, and there are two ways to do it.

  • Turn off the TV, remove the power cord, and place it back after a few minutes. 
  • The second method requires long-press the volume button and power key simultaneously on the remote till it reboots. You can release the buttons once the LG logo appears on the screen. 

If this doesn’t work, try resetting the audio settings on your TV. This can be done like this:

  • On your TV remote, press the “Menu” button.
  • Select “Audio” and press “Enter.”
  • Click “reset” and then enter.
  • You can change the audio setting to your preference and exit the settings.

If still, the problem continues to occur, try pairing external speakers. If the audio is heard through external speakers, then you need to get your TV speaker checked by a professional. 

5. Inconsistent Colors 

The issues with the colors usually begin when the TV turns off by itself, and a popping sound is heard after that.

Once this happens, you might now get inconsistent colors on your screen, just like the color green gets changed. 

This problem is known to occur because of the power supply or the TV being overused. Often we see that a faulty capacitor inside the TV causes such issues.

To solve the problem, you may want to get your TV checked by a professional from an authorized repair center and get the damage repaired. 

6. HDMI Not Working

If you have LG OLED TV, you are most likely to face HDMI 2.1 port issues.

It is reported that particularly the OLED TVs of the 9 and the X series are not able to handle high-quality outputs.

If you face any issues with HDMI ports, you can get your firmware updated. For this, follow these steps:

  • Go to the settings “menu” from the upper right corner of your home screen. 
  • From the “settings,” select the “general menu.” 
  • You will find the update options in “About this TV” once you scroll down. 
  • Install the update according to your TV, and after this, make sure to reboot the TV as this will help the software to get into effect. 

7. Horizontal or Vertical Bars Appearing on the Screen 

The continuous horizontal lines from the top to the bottom region of the TV screen are indeed very irritating.

This is known to occur due to the weak signal strength your TV is receiving. Damage to the display panel can also trigger this issue.

The solution to it can be highly efficient signal input. For this, you can use a box cable like a high-definition set-top box. 

If your software needs an update, make sure you do it, as this can also help get rid of such horizontal or vertical bars’ appearance. 

8. Sound With No Picture

If no picture appears on your LG TV screen, but still you can hear the sound, there must be some backlight issues (if you have an LCD screen), a temporary glitch, an interrupted power supply, or outdated software.

However, that means that your TV is still alive, and you can simply solve the issue by following these steps.

  • Try rebooting your TV. You can do this by unplugging the TV from the power supply. After about 10 minutes, plug it back in and then long-press the “power button” on the remote for 15 seconds.
  • Check for the cables. If they are loosely connected to HDMI cables or other sound and video-related cables, make sure you do it properly. 
  • If you have an LCD screen, you must check for its screen. To do it, take a flashlight and hold it close to the TV screen. If you see any picture where the light is being shed, then this indicates that the backlight is broken. This will need a repair, or you must upgrade to a new smart LG TV or a new TV Brand

9. False Countering or Posterization 

On the screen, you might get to see some unrealistic solid color strips. This issue is known to be false countering to posterization.

This usually happens when the TV screen is unable to handle the colors of the video content properly.

LG has not provided any long-term fix for this issue yet. However, all you can do is check the display before purchasing a TV.

Check for any signs of banding when you test the display. If you already have purchased a TV and experiencing the issue, you can go to the color settings of your TV and try adjusting some features which seem to reduce the effect of banding.

10. Not Showing up on Airplay

If your TV supports AirPlay, and you are facing any connectivity issues with this feature, you try several things which we have listed below.

Remember that the AirPlay feature is only found on iOS devices and is not supported by Android devices. 

  • Firstly ensure that both devices, i.e., LG TV and any iOS device you are using, are close enough to be paired. If you try connecting it too far from your TV, the signals won’t reach the device.
  • Check if your TV and phone are connected to the same Wi-Fi network. This is quite obvious, but it is observed that many people often forget about it. 
  • One more thing that you can do is to connect the router to the TV via ethernet cable directly. After this, you should be getting the AirPlay connected.
  • Make sure that the AirPlay is turned on because sometimes it automatically gets turned off due to a software update or a reset.
  • Lastly, you can try rebooting your TV if nothing works.

Pros and Cons of LG TV


  • LG OLED TVs provide high image quality. This means that organic LED technology lights up the screen in the best way. The pixels are independent of each other and form sharp images with natural colors.
  • LG OLED TVs can give you the best HDR experience as they support Dolby Vision and HDR10 content. This makes the TVs great for streaming purposes.


  • Comparatively costly than other brands in the market out there.
  • Despite being muchly more advanced, OLED TVs are more likely to burn in and damage than LEDs. 


Undoubtedly, LG TVs are great when it comes to quality but just like every other electronic device, problems are with it as well. 

Some minor issues can surely be dealt with by the procedures we have shared above.

But for some technical LG TV problems, you will require service and assistance from expert technicians.

If you face any such problems with your LG TV and are unable to figure out what to do, you can always contact LG’s customer support.

They will definitely help you out with every step and ensure a friendly user experience for you.

  1. Just bought lg 43lq60006la .Connected both aerial and satellite connections . receive aerial pictures fine but how do you cross over to satellite mode.

  2. 2021 OSweb 52″ LG. Picture goes to lines or blank after 5 mins. sound and remote functions work. re-set and updated – cleared cache – problem continues. AC power is OK (no flux or drops), connected via wifi for signal (tested and works) any ideas.

  3. My 150cm LG TV has suddenly developed an issue whereby the picture goes out of focus for a few seconds and then refocuses only to go back to out of focus – it happens continuously. Any ideas?

  4. I have LG 49um7000pla. It was working fine but all of a sudden it lost the picture some time after that the sound got lost too. I am able to turn the tv on and off with the remote but it doesn’t show a picture. It becomes light grey or blue depending on if it’s dark in the room or if it’s light it looks like it’s light blue. I’ve tried to reset it (1 minute at least out of power). Didn’t work. Tried to reset the tv receiver or hdmi port too but no luck.
    Could it be because there is fluctuation in power voltage. I’m in a country where we use 220V but I’ve noticed from a few months ago there were some days that the lights at home start to flicker. There were a few times not that it went down to 180V. This has happened to the whole village I live in, not only in my home. I suspect this is still happening because my lamp was doing that today too for the last few hours and this is when the TV became like that. Is it possible that because of the low power the TV got bad now and it might have to go to repair or maybe when power is at 220V it’ll just be fine again.
    Also when the Tv is off the red light under is lit and when I turn the tv on it blinks 3 times and then turns off. Dose that means/indicates some kind of error or is it just me overthinking?

  5. my 65 in smart lg tv has a very bright 1 inch wide x 6 inch long white streak in the center of the tv about 10 inches from the bottom checked all connections & replaced the tv cable box when a person or something dark comes on the tv you cannot see it

    • It sounds like the white streak you are describing is most likely a display issue with your TV. This type of issue is commonly caused by a problem with the TV’s backlight or a problem with the display panel itself.

      Here are a few things you can try to troubleshoot the problem:

      Check the TV’s backlight settings: Make sure the backlight setting on your TV is not set too high, which can cause a bright white streak to appear. You can adjust this setting in the TV’s menu.

      Check for any physical damage: Check the TV’s screen for any physical damage that may have caused the white streak. This could include cracks, scratches or pressure marks.

      Check the connections: Make sure that all the cables and connections between the TV and the cable box are secure and that the cable box is working properly.

      Check the firmware of your TV: Sometimes, the TV could have an outdated software that could cause this kind of malfunction. Therefore, checking for any firmware updates and updating if necessary.

      Factory Reset: Sometimes the TV may need to reset, if you haven’t try this, it could be a solution to the problem.

      If these troubleshooting steps do not resolve the issue, it may be best to contact LG customer service or a professional TV repair technician for further assistance. The white streak could be an indication of a hardware malfunction that would require professional repair or replacement.

  6. My LG tv has been great until recently. When i change the volume there is voice gives me the volume number. How do i stop this voice?

  7. My wall mounted TV will occasionally turn itself on during the night with no sound. I tried the reset function previously and seemed to work for a while, but seems to have returned. What next?

  8. I have aLG OLED 55 C14LB tv tried to reconnect some aventree headphones via the toslink cable (headphones communicate with a transmiiter via bluetooth so effectively a wired item) a sound share screen appears stating that the item is ready for use but it is nigh on impossible to get rid of that sound share screen. I even tried the headphones on a Panasonic tv in a different room and the sound share screen appeared on the LG tv ??? both tvs connected to the internet.

  9. I bought my LG 32″ HD Smart webOS TV Jan.29, 2022. It constantly interrupts my viewing with a screen that reads “channel no longer available, please return to previous channel”. After doing this, my previous channel returns.
    Today, 10/05, I am unable to view certain channels, which gives me a black screen on several channels, and limited access to channels I viewed the day before.
    I remain dissatisfied with this TV and seriously considering sending it to the junk yard and buy a different brand model. The date to return this junk is past due.

  10. my L G is a 2016 model49uh6100. The tv has a blue tint that I cannot g, I have tried many adjustments to get rid of the tint, even white objects on the screen appear to have a blue tint. Is there a easy to get rid of this problem.

    • Hi David,

      A manufacturing fault in the blue LED backlight may be the origin of the blue tint on your TV’s screen. You will need to change your backlight in this situation. The last and most frequent reason for the blue tint—or any tint—is an issue with the image or display settings.

  11. Our LG tv kept going off and coming on all by itself. I contacted customer service three different times and they were unable to resolve the problem. They asked me to take a picture of the tv and remote and send via messages and they would send a receipt for a replacement. Never heard anything back. Will NOT be buying another LG tv!

    • Hi Susan,

      Your TV probably uses power-saving features like idle TV standby, on timers, and sleep timers if it goes on or off at regular intervals, such every 30 to 60 minutes. Check the Bravia Sync settings if the TV goes on or off whenever an HDMI-connected device is switched on or off.

      • Mine turns off and on by itself too. We were told to turn off tv and unplug connection. Hold in the turn on button for the TV for 2 minutes wait one minute plug back in and wait till process is back. Then turn tv back on. We have done this but now it still keeps turning off and on. what else can we do?


  13. My LG television which I purchased less than a month ago no longer has any color. It only has a black and white picture which isn’t acceptable.

    Please Advise

  14. I have no color on my television. Black and white only, We have unplugged, reset fire stick. Most everything we can think of. It is still black and white. I did use the sleep timer last night. I have used it before with no problems.

    Please advise.
