Having a smart TV is a convenience that we can really appreciate. If you are having a problem with your Samsung TV cast not working, however, it makes that convenience a real problem.
A restart of both the TV and the device trying to cast to the TV will often fix the problem with the cast not working. After restarting, you may need to pair the phone with the TV and make sure you are on the same Wi-Fi. Aside from that, turning off the Bluetooth on the Samsung TV may help.
This is only one of many options but you may find that it fixes almost any problem you are having with your Samsung TV.
Samsung TV Cast Not Working
One way to fix most problems with a Samsung TV, including when the cast is not working is to do a cold reboot. This can be done in two different ways. Use the remote control or unplug the TV.
Reboot the TV
Using the Remote Control
The TV must be turned on to do a cold boot using the remote control. Begin by pressing the power button and holding it until the TV turns off. Continue to hold down the power button until the TV turns back on.
When you reboot the TV in this way, it will clear the memory. It may help to fix any problems with the TV running slowly or the cast not working.
Pulling the Power Cord
You may also need to use the television controls as you may find it to be a more thorough reboot. This process also begins with the television turned on.
Pull the power cord from the power outlet and wait for 30 seconds. Plug the TV back in again and then press the power button.
This process will discharge the energy from the TV and clear the memory cache. You will typically find that it helps the television run smoothly.
Check for too Many Connected Devices
Navigate into the TV settings on your Samsung TV and clear all connected devices. You can then add the devices back in, starting with the one you are trying to cast from.
Move Closer Enough to the TV
Although Wi-Fi has a long range, it is always better to get closer to the TV to avoid any connection problems. You will not likely have to stay close to the TV but connecting while you are close to the TV may help.
Check Your Wi-Fi Settings
In order for casting to work as effectively as possible, you have to be on the same Wi-Fi on both the Samsung TV and the device that is casting.
Use the primary Wi-Fi connection in the home. Do not use the guest connection as it may have limitations and avoid using a hotspot as the connection is not typically stable.
Turn off Bluetooth
You will not use Bluetooth to cast to your Samsung TV. It uses Wi-Fi for the process.
If you have Bluetooth turned on, it may confuse the connection process to a certain extent. Disconnect Bluetooth by turning it off in the settings menu on the Samsung TV.
Update Your Telephone App
If you are trying to cast to your Samsung TV from your phone, try updating the app you are using. You might also try casting from a well-known app, such as YouTube.
Try Another Device
When you are confident that your phone or other device used to cast from is working properly, try casting to another device. It could be another TV, laptop, or phone.
You might also try casting to your Samsung TV from a different device. This will help to identify if it is a problem with your phone.
Check for Updates
Along with checking for updates on any app you are using, it’s also a good idea to check your phone, tablet, and Samsung TV for updates.
You will typically find information on available updates by checking in the settings menu under system information.
Try a Different App
If all else fails, try using a different screen mirroring tool or app on your phone or tablet. YouTube is always a good one to try because it is well known and stable.
Check Phone or TV Compatibility
If you are using an older phone or an older Samsung TV, it may not be compatible with casting. You may be able to cast to the TV using Chromecast or another device connected through one of the HDMI ports.
Samsung TV Cast Keeps Buffering
If you have been using the Internet for any amount of time, you remember the days when videos used to buffer constantly. This shouldn’t be happening on your Samsung smart TV.
Generally speaking, a Samsung TV will buffer because you are using too much memory with other apps. Your TV is just like your computer, if you use more of the memory, then it will run slowly. You may notice this when the TV is turning on slowly or if things are not loading properly. Buffering with casting is also a common issue.
Often, booting your TV is going to help solve the problem. The easiest way to do so is simply unplugging the TV from a wall. Make sure that the TV is turned on when you do it.
After unplugging the TV, wait for 30 seconds and plug it back in. You can then press the power button on the TV to turn it on. This will clear any apps in the memory cache and discharge the TV. The buffering should stop.
Have you tested your Internet speed recently? Running an Internet speed test will tell you if there is a problem in your area or your home.
If your Internet speed is slow, it will likely cause buffering problems on the device that is casting and it will reflect on your TV screen. Otherwise, it may be a problem with the Wi-Fi.
Make sure that both the TV and the device that is casting are on the same Wi-Fi, preferably your home Wi-Fi. Avoid using guest Wi-Fi or hot spots.
Samsung TV Cast No Sound
If your Samsung TV is casting properly but there is no sound, it is a frustrating experience. Here are some options to get it working again.
Typically, if the speaker selection is not set properly in the TV settings, the Samsung TV will not cast sound. You will see the video, but the sound will not come through. Check the settings on the TV to make sure you have selected the proper speaker, whether it is internal or external.
Are you using cables to connect your TV to an external speaker or soundbar? If so, you may have a problem with the cables.
If you have been using the speaker successfully for quite some time, check the cable for any damage. Make sure that it hasn’t come loose from the connection and reseat the cable on both ends.
If you are just setting up the sound, you may be using an old HDMI cable. HDMI has updated over the years and you should buy a new cable if you haven’t done so in a while.
You might also try rebooting the Wi-Fi router and turning off Bluetooth on the TV if you are still not getting sound.
Samsung TV Cast Not Connecting
If your Samsung TV cast is not connecting, there may be an easy fix.
Restarting both devices may help to get the cast up and running again. Begin by hard resetting the TV, unplugging it from the wall, and waiting 30 seconds before plugging it in again. Restart your phone or other device used for casting from the settings menu.
The device you are using to cast will send the signal to your Samsung TV through Wi-Fi. It is imperative for both the TV and the device to be on the same Wi-Fi network.
If you have a guest network set up at your home, you may have limitations that will keep casting from working. Always use the primary Wi-Fi network at your home for casting.
If Bluetooth is turned on, try disabling it on the TV through the settings menu. Sometimes, items connecting through Bluetooth will stop the cast from connecting.
If all else fails, reboot your Wi-Fi router by unplugging the power and all cables for five minutes. Wait for it to boot up again after you plug things back in and try to cast again.
Samsung TV Cast Black Screen
There is nothing more disappointing than casting a video and seeing a black screen on your Samsung TV. Here is how to fix it.
A restart of both the TV and the device used to cast will often fix the issue. Perform a hard reset, unplugging the TV while it is on and plugging it back in after 30 seconds. Reset your device using the settings menu. After both have been reset, the memory should be refreshed and it should stream properly.
Have you tested casting to another device? Doing so will help you determine if it is a problem with your phone or with the Samsung TV.
How strong is the Wi-Fi connection? If you are trying to cast from a considerable distance away from the Wi-Fi router or if there are many objects in the way, the signal could be weak.
If you have another device, such as a laptop or a tablet, try casting to the Samsung smart TV using it instead of the primary casting device.
Samsung TV Cast Keeps Disconnecting
When your Samsung TV cast is disconnecting frequently, it is a frustrating experience. Fixing the issue often takes less than five minutes.
If the Wi-Fi is dropping, it will stop the cast from working. It may turn on and off as the Wi-Fi turns on and off. Make sure you are on the primary Wi-Fi and not on guest Wi-Fi or hotspot. Unplug the router and wait five minutes before plugging it back in. Try connecting again and casting.
Connecting from a different device or connecting to a different device will often tell you where the problem lies. If the problem is with the TV, try doing a hard reset.
When your Samsung TV cast is not working, a hard reset can be performed easily. Turn the TV on, unplug it from the wall and wait 30 seconds. After you plug the TV back in and turn it on using the power button, the memory will be refreshed. This will often fix any casting problems that you are having.
