            To play video files on the TV, the file extension, codec, and other requirements must be met.<br>
            If only a specific video file cannot be played, it is not a problem with the TV, but a codec used in the video file is not supported by the TV.<br>
So it's not a product defect and you need to check the file and TV for compatibility.
        </p>        <p>You can check the codec information of video files by installing a third-party video encoding program on your PC.</p>

<strong>Encoding</strong><br>
A process of compressing the data for reducing the size of video, image, or audio files.

<strong>Codec</strong><br>
A compound word created by combining the words 'coder' and 'decoder', representing a protocol to digitize analog signals and save/play them.<br>
A wide variety of codec types exist, including MPEG and WMV series.
