An older television is bound to have numerous issues. Check to see if your television is less than ten years old or if it has recently developed minor issues, as you will most likely need to replace it.

Do not do so until you have exhausted all of the solutions in this article. While we’re on the subject of old smart TV, lg tv, samsung tv another reason yours isn’t showing anything but you can still hear sound bar is that the software on it hasn’t been updated.

tv screen off but sound on

On TVs, especially smart TVs, old software causes a slew of issues. So, if you have a smart television, make sure it is up to date. I’ll demonstrate how to do this down below to safe mode.

Behind your screen, the display boards and power boards may also be damaged. If your television has been damaged or has fallen from its original position, it may no longer function.

1. Outdated Firmware

If your TV screen remains blank but you hear sound bar from it, it may be time to update the firmware, which may be outdated. This primarily applies to smart TVs and not standard roku TV, but if your television has this option, take advantage of it because you will not be able to do so on all types of TVs.

It’s not a problem if you don’t know what firmware is. Firmware serves as a link between software and hardware. Firmware is the software that connects your hardware device to the operating system like a nintendo switch.

The firmware, for example, is what connects your television to the internal software. Updating it may resolve the issues that were causing the black screen in the first place.

Graphic drive updates are also included in these types of updates. So you won’t have to worry about hearing but not seeing your television. Read the steps below to perform this type of update in screen mirroring.

Take your television remote and navigate to the Home section. Remember that these settings will vary depending on your television. Once you’re there, go to Settings and select Support, or whatever option is similar on your Samsung Smart TV, as this only applies to certain models.

Tap on Software Update, then Update Now. After you’ve done this, the update file should start downloading power cord.

Follow the on-screen instructions to install the actual update and check to see if you’re still seeing a black screen. If you’re wondering why your television screen goes black, this is probably why there’s a problem in power button.

2. Change HDMI Cable

Another thing I would try is to replace the HDMI cable you’re using. The HDMI cable is typically one of the primary reasons why you aren’t seeing any images but your sound is still working.

If you notice physical damage to your HDMI cable, you will need to replace it because it is most likely the source of the problem here. Because HDMI port are expensive, they will be simple to replace.

Make sure it’s long enough so you don’t have to move your flat screen TV closer to your smart hub or wherever you plug in your cable. First, before you buy anything, try moving your cable around to see if you can see anything on your screen new window.

If it glitches temporarily and you can see something, your cable may be faulty. If you’ve moved it around and the sound is still working but nothing appears, try the other solutions listed below for home theater.

3. Check Power Supply Board

A power supply board failure is the most common cause of a blank screen on your television. When the power supply board fails, the display almost always fails.

Most televisions include a power supply board as well as a T-Con board. Pixels will almost never appear on your screen if your t-con board is faulty. The t con board is also in charge of the lines on your television.

To determine if the problem is with the power supply, connect your television to another source, such as your PC, and see if you can see any images on your television. If you still aren’t, return to the original source.

If you know the t-con board is bad, you can try replacing it. To determine whether your icon board is the source of the problem, measure the voltage being relayed. This can also be done visually.

Check to see if the TCon module cable is properly connected to your display. If it isn’t, insert it properly. Examine the flat cable connector for any dirt or debris.

4. Change TV Power Board

If none of the solutions above worked for you, you should replace your TV power board as this is the only viable option. If you do not know how to replace it, you can have it replaced by a technician.

It can be quite complicated if you don’t know what you’re doing, so this will come in handy. You can always look up some tutorials to learn how to do it yourself.

To do it yourself, first obtain a soft cloth to cover and protect your television screen. Get a crewer driver and place your television in front of it.

Now carefully unscrew the bolts in your television to expose the back. You must now locate and replace the fuses on your television. They are usually five in number.

Remove the screws holding the power board and replace it with the new one. Once finished, replace all of the screws in the power board and the screws connecting the back of your television.

5. Turn Off Sleep Mode

The first thing to remember is that this mode may be referred to differently on different television models. It is also known as power-saving mode, power preservation mode, or power consumption mode, so anything that sounds similar to this is most likely the same function.

This setting is usually found in the general settings on your television, depending on the model, but just know to go into the settings to see this function. When you turn off this feature after a few minutes of inactivity, your television screen will turn off and no sound will be played.

If you use a source device, the sound may remain on even if the television is turned off. This can happen if you have a PC or console connected and are using your television as a monitor.

It’s the same with your phone. The screen turns off after a few seconds of not being touched. To avoid this issue, you must disable this in your general settings.

6. Factory Reset TV

If your TV has been updated to the latest firmware version but you still see a black screen issue, the source or graphics driver is corrupted. One of the most effective ways to resolve this issue is to perform a factory reset on your television. A reset will erase all data stored on the television.

When you reset your television, all of the passwords that you have stored on it will be erased. Other information, such as wifi passwords, will also be erased, so keep this in mind.

All other items, such as apps, will be deleted, so make sure it is a critical decision. Backing up your television is one way to avoid all of this. This is usually found in the TV settings.

After you have created a backup of your television, navigate to the Home section of your television and then to Settings. When you’re in Settings, go to General and then select Factory Reset.

All you have to do here is enter the default pin for most TVs, which is simply 0000. After that, you must wait for the television to reset.

You may need to perform the initial setup of your television after you have reset it, but once done, check to see if the black screen issue problem persists on your tcl tv LED or LCD. If this is the case, proceed to the next solution.

7. Examine the Cable Connections

One of the best ways to resolve this issue is to unplug all of the cables from your smart or standard TV and hub and then reconnect them. Remember to leave the power on cable connected if you want to see what’s going on with your screen. The first cable I’ll look at is the HDMI cable, as this is usually the source of the problem.

Many users who fully inserted their HDMI cable were able to resolve this issue, so it is best to start by removing it and then reinserting it. If you aren’t seeing many changes, you may need to replace your HDMI cable, which I demonstrated above.

If possible, try to look at your television while this is happening to see if it is affecting your screen. After that, check to see if you can see the image on your screen. If that doesn’t work, try unplugging other cables.

When doing this, make sure to insert the cable slowly and carefully because it is easy to break certain cables, especially if they are longer. If possible, position yourself behind the television.

8. Restart TV

This could be the case if your LED TV hasn’t been turned off in a while. When a TV hasn’t had a chance to reset or reboot, the constant use of said TV may cause it to overheat and damage it.

This is extremely unlikely, but if you haven’t noticed your TV hasn’t been turned off in a while, this could be why you’re seeing nothing on your screen but the sound is still playing.

Turning it off for a few hours to cool down is the best thing you can do. If your television is usually turned off at night, you can use the sext solution because it has downtime during the day.

However, if your TV is constantly on, turn it off for a day or two. After you’ve turned it off, turn it back on to see if the problem persists. Put the TV in another room if it is in a hot tv remote.

CONCLUSION Of Tv Screen But Still Sound Still Works

Hopefully, you’ve resolved your display issue by now. If you’re still hearing sound but your screen is black, it may be time to replace your television or have it repaired. This can be quite expensive if you don’t have a warranty on the television. If it is covered by a warranty, you may be able to get it at a reduced price.

Remember that the most important thing to do is to ensure that the HDMI cable is properly inserted. If this is not a problem, it is most likely causing this problem.
