sound or distorted
picture/sound from an
external device
Ensure that connection to the device is correct and that all cables are fully inserted.
Remove and reconnect all cables connected to the TV and the external devices. Try new cables if possible.
Restart the connected devices by unplugging each device's power cord and then plugging it in again.
If "No Signal" is displayed on the TV, ensure that the correct input source has been selected.
When using the Component Video connection, confirm that the Green (Y), Blue (Pb), and Red (Pr) jacks are plugged into
their proper connectors.
When using a 4K playback device, ensure the cable is a High-Speed HDMI cable and adjust Settings > Device Preferences
> Inputs > HDMI-EDID setting.

When using Wi-Fi, make sure the Wi-Fi password is entered correctly.
Turn off the access point. Wait for 2 minutes and then turn them back on.
Ensure that there are no obstacles between the TV and the access point. (The Wi-Fi strength can be decreased by
appliances, cordless phones, stone walls/fireplaces, etc.) Reduce interference by not using or turning off other wireless
devices.
If the Wi-Fi connection fails, connect the TV to the access point via a LAN cable. If the TV can connect via the wired
connection, there might be a problem with the Wi-Fi access point. In this case, try using a different access point.
When using a LAN cable, use one rated CAT 5 or higher. Make sure it is plugged in at both ends.
When using a static IP, ensure network addresses are entered correctly.
If the problem persists, contact your Internet Service Provider or modem manufacturer.

Ensure the TV is connected to the Internet.
Ensure the TV has a high-speed internet connection to get the best streaming picture resolution.
Check your streaming service subscription level.
An unstable Internet connection may cause delays or interruptions. In addition, applications may terminate automatically
depending on the network environment. If this occurs, check your Internet connection and try again.
