• Change Picture format to Original.

Computer picture is not stable

Make sure that your PC uses the supported resolution

and refresh rate.

Sound

No sound or poor sound quality

If no audio signal is detected, the TV automatically

switches the audio output off — this does not indicate

malfunction.

• Make sure that the sound settings are correctly set.

• Make sure that all cables are properly connected.

• Make sure that the volume is not muted or set to

zero.

• Make sure that the TV audio output is connected to

the audio input on the Home Theatre System.

Sound should be heard from the HTS speakers.

• Some devices may require you to manually enable

HDMI audio output. If HDMI audio is already enabled,

but you still do not hear audio, try changing the digital

audio format of the device to PCM (Pulse Code

Modulation). Refer to the documentation

accompanying your device for instructions.

HDMI and USB

HDMI

• Note that HDCP (High-bandwidth Digital Content

Protection) support can delay the time taken for a TV

to display content from an HDMI device.

• If the TV does not recognise the HDMI device and

no picture is displayed, switch the source from one

device to another and back again.

• If the picture and sound of a device connected to

HDMI is distorted, connect the device to another

HDMI port on TV and power reboot your source

device.

• If the picture and sound of a device connected with

HDMI is distorted, check if a different HDMI Ultra

HD setting can solve this problem. In Help, press the

colour key  Keywords and look up HDMI Ultra

HD.

• If there are intermittent sound disruptions, make

sure that output settings from the HDMI device are

correct.

• If you use an HDMI-to-DVI adapter or HDMI-to-DVI

cable, make sure that an additional audio cable is

connected to AUDIO IN (mini-jack only), if available.

HDMI EasyLink does not work

• Make sure that your HDMI devices are HDMI-CEC

compatible. EasyLink features only work with devices

that are HDMI-CEC compatible.

HDMI eARC is not working well

• Make sure the HDMI cable is connected to HDMI 2.

• Make sure the Ultra High-speed HDMI cable is

used for eARC connection.

• Only one eARC device is available at a time.

No volume icon shown

• When an HDMI-CEC audio device is connected and

you use the TV Remote Control to adjust the volume

level from the device, this behaviour is normal.

Photos, videos and music from a USB device do not

show

• Make sure that the USB storage device is set to Mass

Storage Class compliant, as described in the storage

device's documentation.

• Make sure that the USB storage device is compatible

with the TV.

• Make sure that the audio and picture file formats are

supported by the TV.

Choppy playback of USB files

• The transfer performance of the USB storage device

may limit the data transfer rate to the TV which

causes poor playback.

Network

Wi-Fi network not found or distorted

• Microwave ovens, DECT phones or other Wi-Fi

802.11b/g/n/ac devices in your proximity might

disturb the wireless network.

• Make sure that the firewalls in your network allow

access to the TV's wireless connection.

• If the wireless network does not work properly in

your home, try the wired network installation.

Internet does not work

• If the connection to the router is OK, check the

router connection to the Internet.

The PC and Internet connection are slow

• Look in your wireless router's user manual for

information on indoor range, transfer rate and other

factors of signal quality.

• Use a high-speed (broadband) Internet connection

for your router.

DHCP

• If the connection fails, you can check the DHCP

(Dynamic Host Configuration Protocol) setting of the

router. DHCP should be switched on.

Poor quality when watching streaming video

• The image/sound quality of stream video is

depending on the original video content provided by

streaming video apps.

• To ensure the best experience of watching

streaming videos, a fast and stable network

connection is essential. The recommended network

connection speed for the streaming videos are as

follows:

- Standard image quality (SD): 5 Mbps

- High image quality (HD): 10 Mbps

- 4K/Ultra HD (UHD): 25 Mbps
