Power/Remote Control Errors

If you experience any of the problems below while using the product, please check the following: There may be no problem with the product.

I cannot turn on the TV.

• Ensure that the TV/display power plug is securely connected to the wall outlet.

• If using a power strip, test it by plugging the TV/display directly into a wall outlet to check if the power strip is functioning properly.

• Check the batteries in the remote control to ensure they are installed correctly. If the batteries are correctly installed, try replacing them with fresh ones.

• Point the remote control directly at the TV from a distance of 1 to 7 meters for optimal operation. 

The screen does not appear for some time after power-on. 

• This is because there is a noise-removal process to eliminate any possible noise that may appear during power-on. This does not mean the product is defective.

The power turns off suddenly. 

• Check whether the Power Off Timer,No Signal Auto Off or No Operation Auto Off is set.

• Some TV models will be turned off automatically if you do not press any buttons for 4 hours even after the TV is turned on at the time set by REMINDER or Power On Timer.

• There is also a chance that the internal protection circuitry has activated because the internal temperature of the product has risen unusually or excessively.

Screen Issues

It says there is no signal on the screen.

• Check whether the coaxial cable or the cable connected to the external device is properly connected to the TV.

• Check if your external device, such as set-top box or Blu-ray player, is turned on.

I cannot see some programs.

Go to SETTING menu and perform Auto Tuning.

• If you are using a set-top box, consult its supplier. 

The screen shakes after the momentary appearance of vertical/horizontal lines and net pattern.

• Connect wireless telephones, hairdryers, electrical drills, etc. to a different power outlet. The problem may be caused by high-frequency electronic devices such as another TV or strong elector-magnetic sources nearby.

There is a difference in picture quality for each programme.

• Depending on the type of videos provided by the broadcasters, programmers may have different image qualities.

• If you are using a set-top box, consult its supplier.

A digitally broadcasted programme stops or its screen is broken.

• This happens when a signal is weak or reception is unstable. Adjust the antenna direction or check the cable connection.

• Perform Manual Tuning if the signal strength is too low in Manual Tuning, contact the broadcasting station or management office to have the signals checked.

• If you are using a set-top box, consult its supplier.

I don’t see anything, or the image keeps flickering when I try to connect the HDMI cable.

• Check whether your HDMI® cable is compliant with the specifications. You may experience flickering or a blank screen if the HDMI® cable is faulty (bent, broken).

• Make sure that the cable is correctly connected to the port. Bad or loose contact may cause display problems on the screen.

The screen is in black and white or displaying strange colors.

• Check the input mode or cable connection.

• Go to INPUT SOURCES to choose the connected input.

ULTRA HD video does not display.

• With some HDMI cables, signals may not be received.

• Change the settings of the connected device to the supported signal.

Sound Issues

The screen is fine, but it does not play any sound.

• Try another programme. 

• If you use a set-top box, there will be no sound if you have set the volume of the set-top box or your TV to 0 or enabled Mute. Set the volume to an appropriate level.

• Go to SETTING menu.

There is no sound coming from one of the speakers.

• Go to SETTING menu.

• When you are connecting to the AV IN/COMPONENT IN, check if the audio left/right (white/red) cables are correctly connected. (AV IN/COMPONENT IN-ports are available in certain models only.)

The TV sound is not synchronized with the picture, or the sound sometimes breaks up.

• If this happens on only some of the programmers, it may be caused by the broadcasting company’s transmission signal. Please have your broadcasting services provider (wired/cable) diagnose the problem.

• If you are using a set-top box, consult its supplier. 

The volume changes when I change the programme.

•  The volume of different broadcasting stations’ transmission output may vary.

• Go to SETTING menu and set Auto Volume to On.

• If you are using a set-top box, consult its supplier.

Network Connection Issues

If you experience any of the problems below while using the product, please check the following: There may be no problem with the product. 

You can check the network connection status as shown below.

• Go to SETTING menu, check Wired Connection (Ethernet) and Wi-Fi Settings.

TV Connection 

• Check the TV or the AP (Router).

• Check the connection status of the TV, AP (Router) and cable modem.

• Power off and power on in the following order;

• If you want to establish a wired LAN connection, check whether an IP address can be obtained from your router properly.

• If you are setting up your network manually, check whether all settings are correct.

• If you want to establish a wireless connection, check the following points as well. If you are using a static IP, enter the IP directly.

Gateway Connection 

• Check the AP (Router) or consult your Internet service provider.

• Unplug the router/cable modem from the wall outlet, wait 10 seconds and reconnect it. Initialize (Reset) the AP (Router) or cable modem.

• Check the AP (Router) manufacturer’s website to make sure your router has the latest firmware version installed.

• If you can't complete this setting, refer to the router's user manual and the instructions provided by your Internet provider.

DNS Connection

• Check the AP (Router) or consult your Internet service provider.

• Unplug the router/cable modem from the wall outlet, wait 10 seconds and reconnect it.

• Initialize (Reset) the AP (Router) or cable modem.

• Check that the MAC address of the TV/AP (Router) is registered with your Internet service provider.(The MAC address displayed on the pane of the network status window should be registered with your Internet service provider.)

Weak Wi-Fi Signal Issues

What causes bathrooms to usually have poor cellular and WiFi signal?

• Bathrooms are usually enclosed by walls which cause attenuation. Rooms, on the other hand, have windows which allow cellular/ Wi-Fi signal to enter and propagate more easily.

• Bathrooms might have metal sheet on the door. This reflects away most of the RF signal.

• There is a network of pipes with water inside which impedes signal and creates multi-path.

• Water (and moisture) absorbs radio signal at higher frequencies.

How to improve the Wi-Fi signal strength?

• You can boost your Wi-Fi signal by restarting the router and testing your internet speed.

• Make your router as close as possible to your bathroom.

• Upgrading your router and adding extenders can also make your Wi-Fi signal stronger.

After passing the above measures, you are still not satisfied with the Wi-Fi signal strength, you must connect to the Internet through Ethernet, and connect your router and TV directly with a network cable.

Ethernet is based upon LAN and physical wired connection for internet communication. Offers better speed, lower latency, and a more reliable connection than Wi-Fi.

Contents Issues

I cannot see any content in HOME.
• You may not be able to see the content if the service country setting has been changed. Change to the service country you are going to use the service from in SETTING menu.
• If you cannot see some apps, it may be because you deleted them. Please reinstall the appropriate app.
• If the app is deleted, you can download the app at Apps store and re-install it.
• The type of supported content differs by country.
• The content offerings are subject to change or interruption by the service provider.

Internet Browser Issues

Some parts of a particular website are not visible when I am using the Internet.

• The Web Browser supports only HTML5 media and not Flash Plug-in.

• The Web Browser does not support plug-in installation.

• On the web browser, it may not be possible to play media files in formats other than:JPEG/PNG/GIF.

• You cannot save attachments or images.

• If the Use Block Ads feature is turned on, the area on the website that appears to show an ad will appear blank.

The Internet browser automatically shuts down when I visit a website.

• The Internet browser may be forced to shut down if the available memory size is not sufficient to accommodate the image information for a website.

When watching a video in Web Browser, the video is forced off.

You may be able to fix this by setting Adaptive Streaming using Java Script to Off in Web Browser. The setting is not applied to tabs that were open before the change, and is only applied to tabs opened after the change.
