Have you ever been in the middle of your favorite show and the tv screen goes black but sound still works? You might be experiencing a common issue called screen-Goes-black-sound. This article will show you how to troubleshoot and fix a TV screen that goes black without sound.
Why Is My TV Screen Black?
This can happen for several reasons, including a defect in the display device, a power outage, or a problem with the signal.
Failure In The Power Supply Board
One of the first things you should do when your TV goes black is checked the power supply board. If the power supply board is malfunctioning, it will cause TV screens to go black and sound to stop.
To fix a TV screen that goes black without sound, you’ll need to replace the power supply unit. The power supply unit is located under the TV and is connected to the TV’s motherboard.
The most common cause of failure for this board is a bad connection. When this board fails, it will cause all the components inside your TV to stop working. Before replacing parts, you should unplug your TV and turn off the power.
Next, remove the screws that hold down your TV’s chassis and remove it from its stand. Then, carefully disconnect all connectors that are connected to this board.
The second thing you should do is check if there are any backlight issues on your TV. Backlight issues can cause a TV screen to go black without sound. To fix this issue, you’ll need to replace the TV speakers.
You can also try adjusting the TV screen brightness or turning off the TV and then again to see if that fixes the issue. If your TV backlight is OK, then it’s most likely caused by a malfunctioning TV speaker.
This can happen if the speaker is too small or not turned on. To fix this issue, you’ll need to replace the TV speakers. If your TV backlight is OK, then it’s most likely caused by a malfunctioning TV speaker.
This can happen if the speaker is too small or not turned on. To fix this issue, you’ll need to replace the TV speakers.

Another common cause of a black screen of death is a loose connection between the TV and speakers. If your TV doesn’t have any sound, you may be able to hear nothing. This is usually caused by a problem with the TV speakers or the TV itself.
A loose connection between the TV and speakers usually means that either the TV speaker cables are loose or there is a problem with one of the connections.
You’ll need to replace the TV speaker or add a new one to fix this. You can also try swapping out the TV for another one. If all else fails, you could also get a new TV.
You can try to tighten up these connections by using a pair of pliers. If this doesn’t work, you may have to replace both sets of cables and repair your TV.
“Sleep Timer” is activated
If you have a TV screen that goes black without sound, it may be because the “sleep timer” is activated, but the sound still fails.
The TV’s sound is activated when the TV is on, but the “sleep timer,” which keeps the TV on for a set period after being turned off, is also activated.
In addition to this, if you have a TV with an “Auto Power Off” function, this may also be the cause.
To fix this issue, turn off the TV and watch TV. If the sound works when you turn on the TV again, your TV speakers are working correctly. However, if the sound still fails when you turn on the TV, your TV is probably out of order and needs to be replaced.
You can solve this problem by checking your TV settings and turning off the “Auto Power Off” or sleep timer or turning off all of your devices’ power-saving functions.
If you experience a black screen of death on your TV, it may be due to a capacitor issue. A capacitor is an electronic component that helps store energy and can help protect your TV from overloading or going out.
If your TV has a capacitor issue, it will cause the black screen of death. If this happens, you’ll need to replace the capacitor as soon as possible. The capacitor can be replaced easily by following the below steps.
Step 1: Remove the TV’s back cover to access the capacitors.
Step 2: Disconnect the power cord from your TV and then remove the screws holding it in place.
Step 3: You will see a large capacitor on your TV, remove it from its position and replace it with a new one. Place the new capacitor and screw it back into the original position.
Now connect your TV back to power and test for the black screen of death. If you have no issues, then you are good to go.
HDMI cables can often go out of order, causing a TV screen to go black and sound to stop. This can be a frustrating experience because you may not watch your TV or hear the sound.
HDMI is a particular type of cable used to transmit high-definition video and digital audio signals. It is designed to work with your TV and allows you to connect high-end devices such as Blu-ray players, DVD players, satellite receivers, and other AV equipment.
HDMI cables are available in different lengths and can be found in most stores that sell home electronics. When shopping for an HDMI cable, make sure that you get one compatible with your TV brand or model because not all HDMI cables are created equal.
You should also make sure that the length of your HDMI cable fits into the port on your TV set. Also, pay attention to the color of the cable and know that some HDMI cables are thicker than others.
You’ll need to replace the entire HDMI cable to fix this problem. It’s essential to do this properly to don’t damage the TV or cause any other problems down the line.
Check the TV’s Input
If the TV has a Jack, make sure it’s working. If it’s not, you can fix the TV by checking the TV’s input jack.
The TV’s input jack is located beneath the TV’s power cord. It looks like a small box with a line running through it. It may have another line running through it too.
This is where you plug your TV’s power cord into. If it doesn’t work, you can fix the TV by checking the TV’s input jack.
Most TVs have an audio/video input jack that you can use to connect your audio or video device. If the TV doesn’t have an audio/video input jack, you can connect it to an audio or video output on your computer or another device to listen to the TV’s sound.
If the Jack is not working, you can replace the Jack by following these steps:
Step 1: Turn off the TV.
Step 2: Unscrew the Jack from the back of the TV.
Step 3: Remove the old Jack by unscrewing it from the back of the TV and pulling it out of its housing.
Step 4: Insert a new Jack into its housing, making sure that it’s aligned with its shape and screwing it into place.
Step 5: Turn on your TV and make sure that everything works properly before you replace your TV’s power cord, or else everything will be messed up again when you try to turn on your TV.
What to Do if Your TV Screen is Black
If your TV screen goes black, but the sound still works, you may have a problem with the speaker. The speaker might be too low or not working at all. If you can’t hear the sound, it means that your TV is either too old or the speaker is too high.
If your TV screen goes black and the sound still works, the first thing to do is check to see if the speaker is low. Low-grade speakers are better than no speakers because they will provide some form of audio when you watch television.
If your TV screen goes black without sound and the sound still works, you may have a problem with the amplifier. Amplifiers help to create and amplify sound on TVs. They are usually located near the front or back of the TV.
If you can’t see any change in the picture or sound when you try to turn on your TV, it means that the amplifier isn’t working correctly, and you’ll need to replace it.
If you’re having trouble viewing your TV screen and sound after turning it off and on again, or if the TV screen goes black but the sound still works, there may be a problem with your set-up.
In many cases, this is a problem with the TV set itself and not with your TV screen. If you can’t fix the TV screen or sound, you may need to replace the set.
