The TV screen is used for displaying the images and videos which are being played on the device. In some cases, if the TV has sound but no picture for no clear reason, then you cannot enjoy any content available on TV.
There is sound, but no picture on the TV screen is a widespread problem in all brands of Television. This problem can be caused due to various reasons.
In this article, we have discussed the potential causes of a black screen with sound. And later, we also discussed the troubleshooting tips to solve the issue quickly and without spending much money. So, read on.
Causes for TV Screen is Black with Sound
If your TV screen is black with sound, many possible reasons may have been causing the issue. And some of such reasons are as mentioned below:
1. Issue with Backlight
If the backlight isn’t working, you will see that the TV has sound but no picture. A multimeter can test whether the backlight is working. It does that by measuring the resistance between two terminals on a power supply board.
If there’s no resistance and the multimeter displays an open circuit, there is no voltage running through your TV. And therefore, no power is coming to your LCD panel.

2. Power Supply to the TV
Check the power supply cable and adapter if the TV is not plugged in. Do not try to use a different power cord or outlet, as this may cause damage to your TV.
If there is no voltage coming through the cord, then it may be defective. So you should only buy a new one instead of fixing it yourself if at all possible.
If there is power going through the cord, but still there is only sound but no picture on TV, check if anything in your home has been turned off. Then make sure both devices are turned on.
3. Issues with TV Panel
The panel is the part of the TV that displays the picture. It’s made up of millions of pixels, which can be damaged or broken. The most common cause is when something falls on top of it, like a piece of furniture or an appliance. If this happens, you will hear the sound but no picture on the TV.
If your panel has been damaged by heat or moisture and won’t turn back on, you will have to replace it with a new one.
4. Bad or Faulty Wiring
If the wires connecting to your Television’s back are loose or damaged, they may need to be reconnected. If they are not connected at all, check whether there was a problem with the installation. Or check if they were never hooked up properly in the first place.
You can also check whether the wiring is connected to the correct place on your TV.
5. Issues with Capacitor
A capacitor is a small electrical component that is used to store energy. It’s found in many electronic devices, including TVs, computers, and chargers. If the capacitor is faulty, it may cause the issue of the TV screen being black with sound. A defective power supply can also cause this issue.
Turn on your TV, and check the circuits before sending any signal to the display panel. If there’s an issue with these circuits or if they don’t work due to a faulty capacitor or another component failure, no signal will be sent out.
And thus, nothing will appear on your screen—even if there is sound from the speakers attached to your TV set!
6. The Sleep Timer is Activated
If you’ve turned on the sleep timer, it will automatically turn off after a specific time. To turn off the sleep timer:
- Press MENU and then press down to highlight Settings.
- Press OK to enter settings.
- Scroll down to the Sleep Timer and press OK.
The Sleep Timer icon appears in the lower-right corner of your screen when active. When this icon is displayed, your TV goes into standby mode after a set amount of time passes without receiving any input signals.

When your TV has sound but no picture, it can be because of a faulty HDMI cable. You can try to fix it by replacing the HDMI cable or using a different one from your collection. You can try using an additional TV and cable box port if neither works.
Generally, ensure that both ends are firmly seated in their respective ports. If they’re loose or bent out of shape, try gently twisting them back into place as best as possible before reinserting them into their ports.
3. Power Cycle the TV
The next thing you can do to troubleshoot the sound issue of sound but no picture on TV is to power cycle the TV.

5. Replace the TV Power Board
