WHDI™(Wireless Home Digital Interface) enables a wireless video link that offers the same functionality as a wired link.

SiBEAM the manufacturer of the Wireless Chip Set used in the first -generation of LG Wireless Televisions used a different technology, based on the 60-gigahertz band of the radio spectrum, with higher speeds but shorter ranges. SiBEAM can transfer data at 4 gigabits per second and has a range of 32 feet.

Power LED If there are questions about the functionality of the

USB Adaptor, first make sure the LED illuminates. If it does not, try any USB jump drive that has an LED. If it lights and the USB Wireless adaptor LED does not, replace the adaptor. Or you can plug the USB Wireless adaptor into any USB port on your laptop. The LED on the side of the USB adaptor should illuminate, it will be dim compared to when it is illuminated by plugging it into the TV, but it should light. If it lights in the Laptop’s USB but not in the TV, check the USB 5V driver IC8000 on the Main board. Pins 2 and 3 should be outputting +5V for the USB.

USB Wireless Broadband/DLNA Adaptor TroubleshootingUSB Wireless Broadband/DLNA Adaptor Troubleshooting

If there are questions about the USB Adaptor and/or the TV’s ability to connect to the internet Access point, try the following checks. You should carry with you a simple Wireless router set up with no security. Disconnect the Customer’s Wireless router and hook yours directly to the Internet feed from the customer’s modem. See if the TV will connect, if the answer is no, then make sure you can connect via your computer. If yes, use a long cable between router and modem and move the router closer to the TV. If this corrects the problem they will need to relocate the router. If not, connect your Wireless Modem via wired LAN connector to the TV’s LAN input. If the TV works this way, the TV is OK. If you don’t have a Wireless router, you can also test the TV’s ability by downloading A trial copy of Nero MediaHome or the latest version of Windows Media Player and installing it on your Laptop computer. (If you have Window’s 7 there’s no need to install Nero Home). Connect your Laptop via wired LAN connector to the TV’s LAN input. You will not be able to see the Internet, but you should be able to see media files in your shared folder on your computer. If you can the TV is working normally and the fault lies with the Wireless USB adaptor.

This concludes theWireless Media training session.
