Problems & Solutions

Note:

problems & solutions 1 to 2 are for the TV models which have network functions, so users of non-connected 

TV models can disregard them.

6.  Video stops playing midway.

-

Mistakes may occur when videos are copied or 

compressed, so they may automatically stop playing 

during playback.

7.  What should I pay attention to, when I do 

software updating?

-

No power cuts when software updating;

-

Avoid any operations with your remote control when 

software updating;

-

Depending on your internet connection speed, the 

software updating process may take some time.

8.  There

are no distinct changes of TV interface 

after software updating.

-

Under certain conditions, software updating may not 

only update or add new functions but also improve 

the performance of the TV set, without distinct 

changes of interface. Also, there may be no changes 

to the user interface at all.

9.  What should I do when software updating 

process stops due to a sudden power-off?

-

If you do software updating by USB, do not pluck the 

USB from your TV, and restart your TV to continue 

software updating; If you do software updating 

by Network, also restart your TV and check if it is 

functioning correctly.

10. With a USB device being inserted into the TV in 

advance, I am prompted that no USB devices are 

detected after I access Media, why?

-

There may be something wrong with your portable 

hard drive(s), damaged or with low voltage. It's 

recommended to provide an additional power supply 

to the hard drive(s).

11. External device cannot be recognized.

-

Some external devices (e.g. webcam, smart phone, 

tablet, game handle, and external wireless adapter) 

may not be compatible with the TV and cannot be 

supported for certain functions (nScreen, wireless 

display, gesture control, face recognition, if any). 

Please try a similar device. If it does not work, 

contact your local dealer.

12. Voice search does not work.

-

Check if your remote control has been successfully 

paired with your TV.

-

Check if the language setting is correct.

-

Check if Google server is available and stable.

1.  Fail to link to the network.

-

Check if your TV is connected with the network;

-

Reboot your TV;

-

Consult your internet service provider, to confirm 

if access of your router is supported. Refer to the 

operation manual of your router.

-

Make sure your TV is connected to a router, and 

make sure your router is powered on. Check that 

your router/modem has an internet connection, and 

that your Ethernet cables/wireless connection is OK. 

Test your connection with a computer to make sure it 

is OK. Should the problem persist, contact customer 

service.

2.  The video could not be played smoothly.

-

Videos from your USB flash drive --- It may result 

from data transmission, or its code flow is far beyond 

the supported formats of this TV set.

-

Videos downloaded from internet, or online videos.
a. It may be caused by the lower bandwidth of your 

network. A high network speed is required to  

handle online videos.

b. Peak internet usage times may affect the 

bandwidth.

c. Check if any other computers on the same 

network are also operating, as they may be using 

up bandwidth. Especially if they are downloading 

or playing on-line videos.

d. The video may not be smooth itself, it is not the 

problem of your TV or network.

3.  When two portable hard drives are connected 

with the TV at the same time, they will not be 

recognized sometimes.

-

All portable hard drives consume a lot of power, 

which may result in power supply problems. We 

recommend inserting only one hard drive, or a low 

power consumption portable hard drive.

4.  The video from a portable hard drive (USB) is 

playing with no sound.

-

The audio format of the video in your portable hard 

drive is not supported by the TV player.

5.  Some videos fail to play.

-

The formats of the videos may not be supported 

by the TV, especially videos shot by certain kinds 

of cameras, generally with their private protocol of 

formats, which are not compatible with your TV.
