LG is one of the biggest names in the TV industry as the brand is the pioneer in OLED panel TVs. Although LG TVs are popular among buyers, some users report LG TV screen issues.
This article is written to address the possible issues with LG TV screens and their solutions.
Let’s begin!
LG TV Has Sound But No Picture
The below solutions will tell you how to fix your LG TV when it turns on; it has sound but no picture. We suggest you try these solutions one after another if the preceding doesn’t work.
Solution 1: Power Cycle your LG TV
50% of the time, this simple solution works for this problem, and LG TV turns on with a proper picture and sound. All you have to do is:
- Unplug your TV from the wall/socket.
- Wait for at least 60 seconds. We repeat, not less than 60 seconds.
- While the TV is unplugged, press and hold the power button on your LG TV for 30 seconds, remember, not from the remote, but from the TV itself.
- Plug the TV back into the socket. This will drain any left-out power in your TV.
- This will reset your TV, and most probably, your LG TV will have both the picture and sound this time.
- Please note that this reset differs from simply turning your TV off and back on using the remote.
If this solves your problem, great! If it doesn’t, move on to the next solution.
Solution 2: Check your HDMI Connection
Nowadays, all video sources, for example, Roku, Firestick, etc., come with HDMI connectors. The problem often lies in this HDMI connection rather than the TV itself.
Check the back of your TV for any loose HDMI connections due to a loose connector or a short cable length. Also, try changing the HDMI port to rule out this reason. Most LG TVs come with two or more HDMI ports. You need to check the sides and back of your model to see how many HDMI ports it comes with.
If this doesn’t work for you, check the backlight.
Solution 3: Check the Backlight
Sometimes the TV’s LED backlights need a replacement, and these faulty backlights are the culprit.
Although, if you have shifted your TV to another room or a building recently, the T-Con board or the main board might get broken; mostly the issue lies in the backlights otherwise.
To check if the backlights are creating the problem:
- Take a flashlight (it can be on your phone, too), and point it close to the TV screen with the TV on.
- If you see a faded image on the screen (you might need to turn the lights off to see the picture), the issue is with the backlights and not the mainboard or the panel.
Although replacing the backlights is easy and can be done at home, it is a good idea to call a technician or contact LG support if your TV is still under warranty.
Please note that if the panel or main board is broken, check for the repair cost, as it might be more convenient to buy a brand-new TV than get the old one repaired.
LG TV Has No Picture Or Sound
We have researched and penned down some easy-to-try solutions for you that will most probably solve this problem of LG TVs having no picture or sound.
Solution 1: Check the Power Source and Cables
Start by checking the power source your LG TV is connected to. Sometimes there is an issue with your electricity supply that does turn the TV On, but the power is not enough for your TV to show the content. Also, the torn-off or damaged power/HDMI cable might be the reason for LG TV neither showing picture nor sound. Moreover, look for the entangled cables to ensure there is no hurdle in the proper content transmission.
Solution 2: Check the Input Channel
Sometimes the wrong TV settings are why your LG TV doesn’t show the picture or sound. To check the input channel:
- Look for a serial number above the HDMI port your video source is connected to. For example, on your LG TV, the HDMI port might be labeled “HDMI IN 2” or something like that. Note that serial number.
- Now grab your TV remote (not the video source’s remote) and click Input or Source.
- Toggle this one until you reach the input channel that matches the one your HDMI cable is connected to.
Solution 3: It’s Time to Repair
If the solutions mentioned above don’t work for you, the problem is inside the TV’s circuitry. Mostly, if the LG TV is neither showing a picture nor sound, the problem might lie in the power supply board or the capacitors.
It’s time to call your technician to troubleshoot this circuitry bug or to contact LG support if your TV is under warranty.
LG TV Picture Freezes But Sound Continues
There might be situations where your LG TV delivers the sound correctly, but the picture gets stuck or frozen. Your first step would probably be to restart your TV to see if the issue goes away. Well, it might go away for some time but rise again after some hours of work. In that case, try the below-mentioned solutions one by one.
Solution 1: Leave LG TV Alone
Yes, you read it right. If you live in a damped or more moistened area, the chances are your LG TV circuit gets overheated due to moisture condensation. In that case, you need to turn the TV off and give it some time to dry. You can use an air blower to help dry the circuitry off.
Solution 2: Ensure that Child Lock is Off
Sometimes if the child lock is turned On on the LG TV, this issue of frozen pictures with sound coming arises. To turn off the child lock:
- Press Menu/Q.Menu button on your LG TV remote. (Some LG TVs have Menu button while others have Q.Menu button)
- Select Options from the pop-up list.
- Select Child Lock and click Remove Child Lock.
- Enter the 4-digit number you had set at the time of activation.
- Click Ok to complete the procedure.
Solution 3: Check the Video Source
If the solutions mentioned above don’t work, you should leave your LG TV alone and turn your head to the video source. Be it a Playstation, a fire stick, or a Roku device, ensure that the video source is adequately powered, connected, and working.
If the source is working correctly, reboot the video source device. Even if that doesn’t work, turn off the LG TV and the device for at least ten minutes and turn them back on (TV first and the device later.)
LG TV Picture And Sound Are Out of Sync
This problem of picture and sound out of sync is called Lip sync or AV sync. It means that the audio and video don’t deliver at the same time. Either the audio comes before the corresponding video or after it.
The AV sync issue might be because of the LG TV itself or the externally connected video source. Please read on to learn how to resolve the issue in either case.
Case 1: AV Sync Issue Due to LG TV
First of all, adjust the AV settings on your LG TV and see if it resolves the issue. To perform these settings:
- Press the Home button on the remote control and select Settings.
- Now select Sound and press Enter.
- Next, select the AV Sync Adjust option and press Enter.
- Set AV Sync Adjust to On and set the external speaker.
- Adjust the speaker slider to the left if there is a delay in the video and sound comes first. Adjust the speaker slider to the right if the video comes first and the sound comes later.
Case 2: AV Sync Issue Due to Cable Device
If you are experiencing the lip sync issue on some specific channels, the problem is in the received signal. In that case, you would want to adjust the lip sync problem manually for each channel by following the steps mentioned in case 1.
Case 3: AV Sync Problem Due to Game Console/DVD Player
If you are experiencing a lip sync issue while playing any game or a DVD, check if the problem is with that specific game/DVD. You can adjust that problem manually by following the above steps. If the problem lies with all the inserted discs/CDs, you will need to contact the manufacturer of that device to resolve the issue.
