I cannot turn on the TV.
- Please make sure your TV power plug is correctly connected to the outlet.
- If you are using a multi-outlet, check if it is working properly. To check whether a power strip is working properly, plug the TV’s power plug directly to a wall outlet and observe its operation.
- Replace the batteries in the remote control. (Use alkaline batteries.)
- Check whether there are any obstacles in front of the TV’s remote control sensor. Sound bars or other obstacles placed in front of the TV's lower receiver may obstruct IR signal reception.
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 thePower Off Timer,No Signal Auto OfforNo Operation Auto Offis 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 byREMINDERorPower 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 connectedto the TV.
- Check if your external device, such as set-top box or Blu-ray player, is turned on.
I cannot see some programmes.
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 problemmay be caused by high-frequency electronic devices such as another TV or strong electro-magneticsources nearby.
There is a difference in picture quality for each programme.
- Depending on the type of videos provided by the broadcasters, programmes may have different imagequalities.
- 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 thecable connection.
- Perform ManualTuning if the signal strength is too low in Manual Tuning, contact the broadcasting station or managementoffice 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 flickeringor 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 displayproblems on the screen.
The screen is in black and white or displaying strange colours.

- Go toINPUT SOURCESto 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.

- 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 theAV IN/COMPONENT IN, check if the audio left/right (white/red) cables are correctly connected. (AV IN/COMPONENT INports 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 programmes, 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.

You can check the network connection status as shown below.
- Go to SETTING menu, check Wired Connection (Ethernet)andWi-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 fromyour 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 firmwareversion installed.

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 multipath.
- 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.
