Samsung is a trusted brand in consumer electronics and it has consistently delivered cutting-edge televisions with vibrant displays and immersive sound systems.
However, like any complex electronic device, even the most reliable TVs can occasionally encounter technical issues. One such problem you may come across is the situation where you have a Samsung TV with sound but no picture.
This article shows you five simple solutions that will often get the picture back on your Samsung TV.
Let’s get started!
Samsung TV With Sound But No Picture – 5 Easy Fixes
Here are 5 easy fixes for a Samsung TV with sound but no picture.
#1. Check Cables and Change Wall Socket
This might seem pretty obvious, but it’s the first thing you should do, before trying any of the other fixes.
Check that all the cables going into your TV are properly connected. Pull them out and push them in again, to make sure. Then pull the plug out of the wall socket and plug it into a different wall socket.
When you’re trying to fix a technical problem, always start with the most simple causes and progress towards more complex issues.
#2. Switch The HDMI Input
If that didn’t fix it, you next need to check the HDMI cable. This is a common cause of sound but no picture on Samsung TVs..
The HDMI cable is used for transferring high-definition audio and video from a peripheral device to your TV. An HDMI cable is used to connect cable TV/satellite boxes, gaming consoles, Blu-ray and DVD players, streaming boxes, or laptop computers.
So this is the first thing to check.
Make sure the HDMI cable is securely plugged into the socket on the back of your TV:
Make sure the HDMI cable is pushed all the way into the socket.
If that doesn’t fix the problem, try moving the HDMI cable to a different socket. Most Samsung TVs have at least 2 HDMI sockets and some models have 3 or 4 HDMI sockets.
Move the HDMI cable to each available HDMI socket, in turn. That may fix the problem.
#3. Verify The Input Source
If you still have sound but no picture, the next thing to do is check the input source on your Samsung TV.
Press the source button on your Samsung remote:
The TV will display all the sources and inputs connected to the TV.
Choose the correct one and press ok.
If your remote does not have a ‘Source’ button, press the ‘Home’ button. This will bring up a menu bar that runs along the bottom of the screen. On the menu, scroll left until you get to the word ‘Source’.
Now check that you gave the correct source for the TV:
#4. Power Cycle Your Samsung TV
If your Samsung TV still has sound but no picture, the next thing you need to do is ‘power cycle’ the TV.
Unplug your TV from the wall socket
Find the power button on the TV. On a Samsung TV, the power button is usually directly beneath the screen on the right side of the TV:
Press the power button for 60 seconds. You need to keep this button depressed for a full minute. This drains the power from the TV and completes the power cycle.
Now plug the TV back into the wall.
#5. Factory Reset Your Samsung TV
If that didn’t work, you now need to do a factory reset. Be aware that a factory reset will delete all your apps and settings.
Press the ‘Home’ button on your remote and then go to Home > Settings > Support > Self Diagnosis > Reset
Check Your LED Backlights
If none of these five fixes solved the problem of your Samsung TV with sound but no picture, it’s time to check the TV screen.
Wait till it’s dark and turn all the lights off. Then shine a flashlight onto the screen, at an angle. If you cannot see any images at all, the problem is most likely the LED backlight strips.
Alternatively, you can buy LED backlights on eBay and replace them yourself. Here’s a video that shows how to replace backlights on a Samsung 65-inch TV:
Replace the T Con Board
If the LED backlights are okay, then it is likely to be the T Con board. The T Con board (or time control board) acts as an interface between the motherboard and the screen of the TV. The appearance of each pixel on the screen is controlled by the T Con board, a process called “pixel addressing”.
These are common symptoms of a faulty T Con board:
- double image
- display distortion
- white display
- vertical or horizontal lines across a screen
- no display at all
- black and white vertical bars across a screen
If your T Con board has blown, you will need to replace it.
You can either have this done by a technician or, if you feel confident with electronics, you can replace it yourself. This YouTube shows you how to replace the T Con board on a Samsung TV:
Contact Samsung Support
If none of the solutions fixed the problem, and you still have a Samsung TV with sound but no picture, then you need to contact Samsung Support.
You can reach Samsung by phone at: 1-800-726-7864 or 1-800-SAMSUNG
You can check if your model of Samsung TV is still covered by warranty at Samsung Warranty Information. Samsung LCD, LED, OLED, and Plasma Televisions are usually covered by warranty for a period of 12 months from date of purchase.
If your Samsung TV has sound but no picture, it may easily be solved by one of the 5 fixes I covered in this article:
- Check the cables and plug the TV into a different wall socket
- Switch the HDMI input – plug the HDMI cable into a different HDMI socket on the TV
- Verify the input source – in the TV’s menu, check that you have the correct input source
- Power cycle your Samsung TV – do a simple power cycle
- Factory reset your Samsung TV – do a complete factory reset
If none of these solutions work, then you need to check the LED backlights on your Samsung TV and the T Con board.
