Keep reading, and you’ll discover how to troubleshoot your LG TV and get the picture showing again in no time.
Check The Power And Connections
When your LG TV has no picture but sound, checking the power and connections is a good first step. Problems often come from loose cables or power issues. Fixing these can bring your picture back quickly.
Verify Power Supply
Make sure your TV is plugged into a working outlet. Check if the power cord is secure at both ends. Look for any damage on the cord. Try using a different outlet to rule out power issues.
Inspect Hdmi And Other Cables
Check all cables connected to the TV. Loose or damaged HDMI cables often cause no picture. Unplug and replug each cable firmly. Test with a new HDMI cable if possible. Also, check other cables like component or AV cables for damage.
Test Different Input Sources
Switch your TV to another input source, such as HDMI 2 or AV. This helps determine if the problem is with one device or input port. Use a different device like a DVD player or game console to test inputs. This step narrows down the cause of no picture.
Adjust Picture Settings
Adjusting the picture settings can fix the issue of no picture but sound on your LG TV. Sometimes, wrong settings cause the screen to stay black while the sound plays. Changing a few options may bring your picture back.
Reset Picture Mode
Start by resetting the picture mode to default. This action clears any changes that may cause a black screen. Go to Settings, find Picture, and select Reset. This step often solves picture problems fast.
Check Brightness And Contrast
Low brightness or contrast can make the screen appear dark or blank. Increase brightness and contrast to a moderate level. Avoid setting them too low. This simple fix can restore your TV’s picture clearly.
Disable Energy Saving Features
Energy saving features sometimes reduce screen brightness too much. Turn off these features in your TV’s settings. Look for options like Energy Saving or Power Saving mode and disable them. This can help bring back a normal picture.
Perform A Soft Reset
Performing a soft reset can fix many TV issues. It clears temporary glitches that cause the screen to go black while sound continues. This simple step often brings the picture back without complex fixes. Try these easy methods to soft reset your LG TV.
Unplug And Replug The Tv
First, turn off your LG TV. Unplug the power cord from the wall socket. Wait for about 60 seconds. This pause lets the TV clear its memory and reset internal components. After the wait, plug the power cord back in. Turn on the TV. Check if the picture returns. This method often fixes small software errors causing no picture but sound.
Use The Remote Reset Option
Your LG remote control can also help reset the TV. Press and hold the power button on the remote for 5 to 10 seconds. This action forces the TV to restart. If your remote has a reset option in the menu, use it. Navigate to Settings > General > Reset to Initial Settings. Confirm your choice. The TV will reboot and clear minor software bugs. This reset often restores the screen without losing saved data.

Update Firmware
Updating the firmware on your LG TV can fix many picture problems. Firmware is the software that runs inside your TV. It controls how the TV works. Sometimes bugs in the firmware cause the screen to go black while sound still works. Updating the firmware can solve these bugs and restore the picture.
Firmware updates improve the TV’s performance. They also add new features and fix security issues. It is a good idea to keep your TV’s firmware up to date. The update process is simple and usually fast. You can update your LG TV firmware through the internet or using a USB drive.
Check For Software Updates
Turn on your LG TV and open the settings menu. Find the section labeled “About This TV” or “General.” Look for the option to check for software updates. The TV will search for new firmware versions online. If an update is available, the TV will show a message. Read the message carefully before proceeding. Make sure your TV is connected to the internet for this step.
Install Updates Via Usb Or Internet
To install updates via the internet, follow the on-screen instructions. The TV will download and install the update automatically. Do not turn off the TV during this process. For USB updates, visit LG’s official website on your computer. Download the latest firmware file for your TV model. Save the file to a USB drive formatted as FAT32. Insert the USB into the TV’s port. Go to the update section in the TV settings. Choose the option to update via USB. The TV will find and install the update from the drive.
Inspect The Backlight
Check the TV’s backlight to see if it is working properly. A broken backlight can cause the screen to stay dark while sound plays. Testing this helps find if the problem is with the backlight or another part.
Look For Dim Or No Light Signs
The backlight in your LG TV makes the picture visible. If the backlight fails, the screen stays dark. You might still hear sound, but no picture appears.
Check the screen closely. Is the screen very dim or completely black? A dim screen or no light means the backlight may be broken or faulty.
Look for any faint glow. Sometimes, the backlight works weakly before it stops completely. This weak light is a sign of backlight trouble.
Test In A Dark Room
Turn off all lights and close the curtains. Watch your TV in complete darkness. This helps to see faint backlight glow better.
Use a flashlight. Shine it closely at the screen with the TV on. If you see faint images under the light, the backlight is likely the problem.
This test helps confirm if the TV shows images but lacks backlight. A working backlight shows a clear, bright picture in a dark room.

Try External Devices
When your LG TV has sound but no picture, external devices can help find the problem. These devices connect to your TV and show if the issue is with the TV or the input source.
Testing with different devices and cables helps identify the cause. This step is easy and takes little time.
Connect A Different Device
Try plugging in another device, like a DVD player or game console. This shows if the TV screen can display images from other sources.
If the second device shows a picture, the problem is likely with the first device or its connection. If no picture appears, the TV may have an internal issue.
Use A Different Cable
Swap out the cable connecting your device to the TV. A faulty cable can cause no picture but still allow sound.
Use a new or known working cable to check. This simple change often fixes the problem quickly.
Contact Support Or Repair
When your LG TV shows sound but no picture, professional help might be necessary. Contacting support or repair services ensures expert advice and proper fixes. It saves time and avoids further damage to your TV. Knowing the right steps for support helps you get back to watching quickly.
Check Warranty Status
Start by checking your TV’s warranty status. A valid warranty covers repairs or replacements at no cost. Find the purchase date on your receipt or box. Visit LG’s official website and enter your TV’s model number. This quick step can save money and stress.
Find Authorized Service Centers
Authorized service centers have trained technicians for LG TVs. Use LG’s support page to locate centers near you. These centers use genuine parts and follow LG repair guidelines. Visiting an authorized center ensures quality service and preserves your warranty. Avoid unauthorized repair shops that might cause more issues.
