Problem & Solutions
1. Failed to connect to network.
- Check if your TV is connected to the network.
- Power Off and On your TV.
- Consult your internet service provider to confirm
if access of your router is supported. Refer to the
operation manual of your router, and activate its DHCP
function, and then link the TV to the network.
- Make sure your TV is connected to the router. Using
your PC, check that the router is functioning. Check
to confirm the name of the router is correct in the TV
menu.
2. Videos do not play smoothly.
- Online videos:
a. Examine your network bandwidth, which needs
to be over 1Mbps for online videos, and 2Mbps
for high definition movies and video programs.
We recommend a 2Mbps (or higher) network
bandwidth and network service provided by a major
network operator.
b. Local peak hours of internet may affect the
bandwidth.
c. Check if several computers are on the same
network at your house, with certain computers
downloading, or playing online videos.
d. Make sure your TV is connected to the router. If the
router is connected and powered on, try to change
to a different router and network line, and use your
PC to test the connection.
3. USB hard drives are not recognized when multiple
hard drives are connected.
- We recommend inserting only one hard drive at a time.
Use a low power consumption mobile hard drive.
4. There are no distinct changes to the TV interface
after SW updating.
- Most software updates do not change the on-screen
display.
5. What should I do if the TV lost power during the SW
update process?
- SW Update using a USB: Do not remove the USB from
the TV. Leave it inserted and restart your TV to continue
the SW update.
- SW update using the network: Restart your TV and
check if it is functioning correctly.
6. No USB device detected after accessing
Multimedia with a USB device connected.
- Your USB device may be damaged or not compatible.
