It might not be a pleasant experience if the audio lags while streaming video on TV. The issue is generally due to poor signal quality or the use of an inappropriate audio format. However, trying to play an unsupported video codec might also be culpable.

The sound delay crops up when there is a significant time gap in the digital to analog-conversion of audio-video signals. Or in some cases, the cables used for transmitting audio may not support a higher bandwidth resulting in sound delay.

Luckily, the issue can be easily fixed with minor tweaks on the sound settings of your TV. You can even set the desired audio transfer rate that perfectly syncs with the video.

Since the sound delay problem on TV is not much of a hardware issue, making a few adjustments to the sound settings should fix the problem. However, you can always restart your TV and sound system as a preliminary fix. Also, don’t forget to check the connection between your TV and sound system.

Here, we have compiled a list of 8 ways to troubleshoot sound delay on TV. Let’s get straight into them.

The channel you are watching may be broadcasting content with delayed sound. So, the first thing you must do is to change the TV channel. If you face the issue only with a particular channel or every channel you watch, there is a problem with the TV signal. Please get in touch with the service provider.

Next, you can change the TV source. If you are streaming through a set-top box over an HDMI connection, stream a video through USB mode. If there is no audio delay while streaming through USB mode, contact the cable service provider and ask them to look into the problem.

However, if the cable provider reports everything as fine on their side, there is likely a problem with your TV. Please move to further fixes discussed below.

If there is sound delay only when streaming particular apps like Netflix or Hulu, there is probably a problem with the app itself. Clearing the cache and app data will help the application run smoothly and fix audio delay issues. Also, updating the application to the latest version can help. Likewise, check if you have a stable Internet connection.

Steps to clear cache data are quite similar in most TVs. Here, we are taking reference to the Samsung Smart TV for elucidation purposes.

You need to set the proper audio delay if you are using a soundbar or home theater system with your TV. Generally, 0 milliseconds is a preferred audio delay on the soundbar because using the audio delay settings on external speakers as well as the TV can create conflicts. Once you set the audio delay to zero on your soundbar, you can select the required delay on your TV.

Once you confirm the audio delay settings of external speakers, you need to adjust the audio settings on your TV. The audio settings should match the audio you are playing on the TV. Else, you may experience audio that is out of sync.

The ideal audio format for your TV is PCM. After setting the output audio to PCM, you should have no audio lag issue. Steps to change the audio format are similar in most TVs. Here we have taken the reference of Samsung TV and LG TV.

Some TV manufacturers like Samsung and LG also provide a built-in option to change the audio transfer rate. With this, you can solve the lip-sync problem in your video. You can either delay or speed up the audio rate as per your requirement.

If your TV has a Game mode available, disabling it can help fix the sound delay on the TV. While your TV is in gaming mode, there is no overhead of additional image processing that helps reduce video lags, but the sound gets delayed. In such a case, disabling gaming mode can help.

Here, we are referencing Samsung TV to illustrate the steps to disable the Gaming mode.

Resetting sound settings can come in handy if you need help figuring out the best sound configuration for your TV or have misconfigured the audio settings. It will reset the customized sound profile on your TV, thus solving the issues with the sound delay.

Follow these steps to reset sound settings on your Samsung TV:

Outdated firmware also causes sound delays on TV. So, updating the TV firmware will solve if the delayed sound was due to a bug or glitch in the existing TV firmware. Many users in the community forum reported that they solved the issue after a firmware update. So, give it a try. You can consult our comprehensive guide on updating the TV firmware for different TV brands.

How To Fix Black Screen On Roku Tv

If a black screen suddenly appears on your Roku TV, it interrupts your streaming experience. Several Roku TV users encountered a black screen with sound playing in the background, especially on TCL TV.

Usually, you get this error due to a minor power glitch or a loose connection. But, a major hardware failure like a damaged backlight inverter or LED strip can be responsible too. Some of the other possible causes are:

Faulty HDMI Cable or port

Enabled Sleep Timer

Auto Power Savings Mode

Problematic Apps

Outdated Software

Before you begin, you can perform a power cycle on your Roku TV when a black screen appears. Unplug the TV’s power cable from the wall socket and leave it for about 5-10 minutes. Then, plug it back in properly to see if it is gone.

If you are using Roku streaming sticks or other consoles, the HDMI input source must be correct. A wrong input source will show you a black screen. Press the Input, Video TV, Video, AUX, or Source button on your remote to change it.

Besides input, you can check if the video cable is loosely connected. Check the HDMI port and re-plug the cable to fit it perfectly. Besides, a faulty or broken video cable can also lead to a black screen while streaming on your Roku TV.

You can switch the cables to see if the cable is faulty. Also, if the HDMI port is not working, check out our other article on fixing the HDMI port on TV.

When you enable the Sleep Timer feature, it will automatically turn off your Roku TV after a certain preset time. If you have probably forgotten to turn it off, you will get a black screen when the TV powers off itself. So you can turn off the Sleep Timer to see if it is the cause.

Pick Off option.

When your Roku TV is idle, the auto power savings mode feature will automatically turn it off to save energy. It can be one of the reasons your Roku TV keeps turning off and shows a black screen. Therefore, you can disable this feature temporarily.

When you enable Fast TV start on your Roku TV, in-built speakers or wireless audio devices will stay connected even when your TV is idle. So, if you can hear the audio but on a black screen, it could be due to this feature. Try disabling this feature from your Roku Settings to verify.

On your Roku remote, press the Home button.

Choose Fast TV start.

If you get a black screen only while launching a specific channel, app bugs might be causing it. You can delete such problematic apps immediately to get rid of them.

Locate and highlight the Application.

On your remote, press the Star button.

Software issues could be another cause of the black screen error on your Roku TV. Usually, Roku releases new software updates to address such problems. So upgrading the operating system with the latest version should solve the error.

By default, Roku TV automatically scans for the latest software every 24 hours during an active internet connection. Although, you can also manually check for the latest updates from settings.

For users who are stuck with a black screen and cannot navigate through the system, you need to perform a hard reset on your Roku TV. Locate the Reset button on your TV. Then, insert a Paper clip inside the hole. Press and hold the button to trigger it. You can set up your Roku TV from the beginning.

Alternatively, you can also use your Roku TV remote to reset the TV.

If a black screen still occurs even after resetting the device, there might be a hardware problem on your TV. For Instance, the LED lighting strips might have been burnt. Or the backlight inverters might be damaged.

LCD TVs have a Backlight inverter that operates as a power source for the Cold Cathode Fluorescent Lamps (CCFL). It helps to produce a clearer image on the screen. Similarly, on LED TVs, there are LED lighting strips to generate images on your TV. But when such components are damaged, you will see only a black screen.

Replacing the part is the most effective way to fix the problem. If your Roku TV is LCD, you can replace the backlight inverter. Since most of the Roku TVs are LED, you can check out our detailed guide to replace the LED strips.

You can contact the Roku TV manufacturer’s support team as a last resort if the error persists. Customer support varies according to the Roku TV brand. So you can check out your brand and contact the support team from the official page.

Tv Won’t Turn On? Here’s How To Fix It

Your TV should turn on after pressing the power button on the remote. However, sometimes, the TV may refuse to turn on.

This issue primarily arises due to hardware failure rather than software issues. Your TV may fail to turn on even if a minor hardware component is faulty. Glitches in the power circuitry and loose cable connections are the key causes of the problem. But, there may be significant issues like a blown fuse or capacitors which may require further troubleshooting.

Luckily, there are a few things that you can look after yourself before taking it to a repair center. Keep reading to fix your TV that won’t turn on.

If your TV doesn’t turn on, it might initially seem like a massive issue. However, you don’t need to panic. Provided that there is no major hardware failure, a few troubleshooting techniques can help you get your TV back.

The issue primarily arises due to power glitches in the circuit board of your TV. You can perform a soft reset and solve the glitch in such cases. Most of the time, a soft reset will solve the problem without further exploration.

To do a soft reset, unplug the power cable from the supply. Wait about a minute. Then, press the power button on the TV panel for about 30 seconds. It will help drain the residual power from the capacitors and solve the power glitch. Then replug the cable and try to turn on the TV. It should solve the problem.

Since the problem is directly concerned with the power supply, you should also check if the power cord of the TV is connected correctly to the wall socket. You can try changing the power socket. You can use an electric tester pin to determine if the socket is faulty.

If you don’t have one, connect another device, like a phone charger, to inspect if the power socket is faulty. If it works, there is no issue with the power socket; the power cord or TV is probably faulty.

Likewise, if the power cord is connected to a voltage regulator, remove it from there and connect it directly to the wall outlet, as a faulty voltage regulator will also prevent the TV from turning on. Next, you need to see if there is any breakage in the power cord. Inspect it thoroughly. If there is any breakage, you can quickly get a replacement cord.

Most modern TVs utilize a voltage level between 110-240 volts to operate correctly. Anything above or below the level can cause issues, and you can not turn on the TV.

You can see your home’s electrical distribution box or sub-meter to know what voltage your TV is getting. If you are using a voltage regulator or a surge suppressor, it will also show the input and output voltage. If it marks a voltage of anything lower than 110V or higher than 240V, the TV may not turn on. You need to contact the electricity distribution center to sort out the problem.

If the cable connections and voltage levels are fine, the power cable connector may need to be correctly connected to the TV. Unplug and re-plug it. Also, see if any debris has collected over the port, as it can interfere with the connection. You can use cotton swabs to clean the port and cable connector.

There can be two cases when your TV doesn’t turn on. First, the LED indicator on the TV glows, but it won’t turn on, and next, neither the LED indicator lights nor the TV turns on. In the former case, chances are high that there is an issue with the TV remote that you are using to turn on your TV.

Please check if the batteries are correctly placed and are not dead. You can try replacing batteries and attempt to turn on the TV again. If not, you can also use the power button on the TV panel to turn on the TV. Moreover, if anything is blocking the infrared receiver on your TV or remote, the IR signals can not transmit correctly from the remote and cause an issue. Verify if that’s the case as well.

Please take off your TV from the wall mount or cabinet and remove its back panel with the help of a screwdriver.

Locate the power circuit board. It is the one that is connected to the external power cord. You can quickly identify it once you dismantle the TV.

Once you do that, it’s time to begin the test.

You should first check if the main board on your TV is receiving power from the power supply board. For this, you need a multimeter. Then, you can start the diagnosing process. You need to check the AC input on the power supply board as well as the DC output from the supply board.

The power supply board has two sides: hot and cold. We measure AC on the hot side while DC on the cold side. Be careful with the hot side, as you can get electrocuted.

A blown fuse can cause the power circuit board to malfunction. It commonly blows out when there is a power surge or lightning strikes. To know if a fuse is blown, inspect the thin metallic wire inside the fuse. If there is a gap in between the wire or a dark smoky substance inside the fuse, you can confirm the fuse is blown. In such a case, you need to replace the fuse.

You can even perform a continuity test to know if a fuse is faulty.

The capacitor is the next component that can get damaged in the power circuit board. Capacitors get worn out over time, causing the power circuit board to crash.

So how do you know if the capacitor is bad? Identifying a damaged capacitor is easy. Simply inspect all the capacitors in the power supply board. If you see any of the capacitors bulging from the top or a liquid (electrolyte) leaking from the capacitor, it is damaged.

Replacing a damaged capacitor can be pretty sophisticated, and you need professional help. However, if you want to replace it on your own, you need to get exactly the same capacitor from the market. The rated capacitance, temperature, and voltage of the new capacitor should be identical to the damaged one.

But we don’t recommend replacing the capacitor on your own, as a slight mistake may end up damaging the entire power supply board.

Now that you performed a power supply test and diagnosed the fuse and capacitor, you must have figured out what is causing the power supply board to crash. If you see everything is fine, there is probably an issue with the display panel of your TV.

Display components like the backlight inverter and T-Con board are most susceptible to damage. Or, in the worst-case scenario, the display panel or the main board itself might be blown out. Please consult with a professional to figure out the case. If you find that your display is broken, please consult this comprehensive guide on how to fix a broken TV screen.

If there is massive damage to your TV, and you plan to purchase a new one, please consult this article on what to do with a broken TV.

Outlook Not Showing Attachments? 8 Ways To Fix

Email attachments allow you to share documents, images, and other files with your contacts. However, if Outlook isn’t showing these attachments, you’re not going to be able to view them.

There are several reasons why Outlook might hide your attachments from view. Don’t let missing attachments ruin your email experience—we’ll explore a few methods you can try to resolve the problem below.

Table of Contents

1. Confirm the Attachment Exists and Check With the Sender

The first thing you should do if you don’t see an attachment in an email is to actually see if the attachment exists. You can usually spot this in your inbox by looking for a paperclip icon next to the email subject. This indicates whether or not the email has an attachment that you can view or download.

To view the attachment, select the email containing it. In the email itself, you’ll see the name of the attachment underneath the recipient and subject title. From here, you can download or preview the file.

If not, you can check with the sender. It’s possible that they forgot to add the file, or they sent a link instead of attaching it. If they made a mistake, you can ask them to resend the email with the intended files attached to it.

2. Close and Reopen Outlook

Sometimes, Outlook may experience a glitch that prevents attachments from showing up. In this case, a simple restart of the app may fix the issue.

If you’re using the web version of Outlook, you can also try reloading your browser or clearing your cache and cookies.

3. Check Your Internet Connection

Outlook needs access to the internet to fetch new emails and download attachments. If your internet connection is weak or your connection is unstable, your attachments may not load properly, making it impossible to download them.

To fix this, make sure your device has a stable connection to a Wi-Fi network. You can also try disconnecting and reconnecting to your Wi-Fi network. If you’re on a mobile device, try switching from Wi-Fi to your mobile data connection (and vice versa).

4. Preview Your Email Attachments

Occasionally, you may not be able to view or download attachments directly from your inbox. In this case, you can try previewing them first (forcing them to load in your cache) before saving them to your device.

To preview an attachment in Outlook, follow these steps:

Open the email with the attachment in the Outlook client.

A new window will open with a preview of the file. This preview will vary, depending on the type of file and your operating system.

If you want to save the file, select



5. Use Pop-Out Compose Mode

You may want to view an attachment in an email while you’re writing up a reply. However, if you use the inline compose mode, you won’t be able to see the original email and its attachments. To solve this problem, you can use the pop-out compose mode.

This will open a new window for your reply, where you can see the original email and any its attachments in the background. This works best for emails that contain images as attachments, for instance, as you’ll be able to preview them properly.

To use the pop-out compose mode, follow these steps:

Open the email with the attachment that you want to reply to.

In the


dialog box, look for an icon that looks like a box with an arrow pointing out of it—this is the

pop-out icon

. It may look slightly different or be located elsewhere, depending on your version of Outlook.

You can now view the attachment in the original email while composing your reply.

6. Drag-and-Drop Attachments When Composing Emails

Another way to attach files to your emails is to drag and drop them from your computer. This can be faster and easier than other methods for attaching files to your emails.

To drag and drop attachments when composing emails, follow these steps:

Locate the file that you want to attach to your computer using File Explorer (on Windows) or Finder (on Mac).

Select the file and drag it with your mouse cursor.

Drop the file into the compose box in Outlook. You may see a message saying

Drop files here

when you hover over it.

The file will be attached to your email. You can repeat this process for multiple files.

7. Delete Your Outlook Cache

Outlook stores temporary files in a cache folder to improve performance and speed. However, sometimes this cache may get corrupted or outdated, causing attachments not to show up.

To fix this, you can delete your Outlook cache and force the app to download fresh files from the server. Once you’ve done this, restart Outlook and try to view the email containing your attachments.

8. Ensure Outlook Isn’t Blocking Your File’s Format

Outlook has a security feature that blocks certain types of files from being attached or opened. These files are usually executable files that may contain viruses or malware. For example, Outlook may block files with the .exe, .bat, .js, or .vbs extensions.

If you’re trying to attach or open a file that Outlook blocks, you’ll see a message saying Outlook blocked access to the following potentially unsafe attachments. To fix this, the original sender (whether that’s you or somebody else) can change the file extension before attaching the file.

To change the file extension, follow these steps:

Locate the file you want to attach on your device using File Explorer (on Windows) or Finder (on Mac).

Change the extension to something else, such as .


or .



Confirm the change and attach the file in Outlook using the steps outlined.

If this doesn’t work for you, you’ll need to contact your network administrator and explain the situation. They may be able to modify the app settings on your device, network, or Microsoft Exchange server to unblock certain file types (either temporarily or permanently).

Fixing Attachments in Microsoft Outlook

If your attachments aren’t showing in Microsoft Outlook, the steps above should help you to fix the problem. You could also try downloading all of your Outlook attachments from your emails if you’re struggling to open them. If you’ve got multiple attachments, you could try attaching a folder to your Outlook email.

Looking for one of your old attachments? You can search through your Outlook emails using specific search criteria (such as the sender).
