Stops during playback
- Keep a distance of at least three meters between the microwave oven, mobile phones,
Bluetooth* equipped devices, or any other Wi-Fi compatible devices.
- Try changing the active channel on the WLAN router.
Internet connection not available / Unable to share audio and video
- If the MAC address (a unique identification number) of your computer or modem has
been stored according to regulations, your TV may not connect to the Internet. In this
case, the MAC address is authenticated every time you connect to the Internet. This is
a precautionary measure against unauthorized access. Since your TV has its own MAC
address, your Internet provider cannot validate this address. As a result, the TV cannot
connect to the Internet. Contact your Internet service provider for information on how to
connect a different device, such as the TV, to the Internet.
- It is also possible that the Internet connection is not available due to a firewall related
issue. If you suspect that this may be the cause of your problem, contact your Internet
service provider. A firewall could explain the connectivity and detection problem when
using the TV in Audio/Video Share mode or when browsing using the Audio/Video Share
feature.
Invalid domain name
- Make sure you are already logged in to your computer with an authorized username/
password and also make sure your domain is active, before sharing any files on your
computer's media server program.
- If the domain is invalid, you may have trouble browsing files in Audio/Video Share mode.
