[LG TV monitor] No sound is outputted when a video file stored in a USB storage device is played

Troubleshooting

In order to play a video file in the TV monitor, it can be played in the TV monitor only when
the information on the video file such as extension, codec, etc., matches.

Causes and Symptoms

  • No sound is outputted when a video file is played on the TV monitor.
  • It occurs because the codec does not match when a video file is played.
  • If only a certain video file cannot be played, it’s because the codec information of that video file cannot be used in the TV,
    and in such a case, it is not a product defect, but a symptom caused by incompatibility between the information in the file and the TV monitor.
  • To check the codec information on a video file, you can check the information on the video file through an encoding program after installing it on your PC.

Encoding
It is a process of compressing data to reduce the volume of original data when video, image or sound data are created using a computer.
Codec
It is a compound word made by combining the initial letters of coder and decoder.
It is a method for storing and playing analog signals by converting them into digital signals, and there are several types such as MPEG series and WMV series.

Playing a video file on the PC

➔ Install an encoding program on the PC, play a video file and check the playing information.

Check the information specifications of video files that can be supported from the play information of video files and the TV monitor.

Checking video codec information

If the video file information is different from the information specifications of video files that can be supported by the TV monitor, such video files cannot be played on the TV.

※ If only pictures (jpg) and music (MP3) are displayed on the screen when a USB storage device is connected, the model does not support the video function.
For accurate information, it is necessary to check the model name and specifications.

Check for playability after encoding
In order to play a certain file that cannot be played on the TV, it should be encoded on the PC.
For encoding, extensions and codecs desired by the user can be set.
For your reference, Daum Pot Encoder, whose stability and performance have been proven,
is used the most widely among free encoding programs in Korea.
Since there is no encoding program operated by LG Electronics, we cannot provide a program.
Specifications of video that can be played on the TV when encoding
(Used for encoding configuration)
① Extension: AVI
② Video codec: Select among H.264
③ Voice codec: MP3
④ Bit rate: Same as the original file (higher the bit rate, larger the capacity)
⑤ Resolution: Same as the original file
