Troubleshooting
• First check if there are problems with files.
a. The files are not corrupted. After you have saved files to a storage device (a USB flash drive) from PC,
please eject the storage device first before you disconnect it from PC.
b. The format of files that can be played depends on the codec and driver of the TV. For example, high-
bitrate or high-resolution files may not be played back smoothly or can't be played. For more information
about the supported codecs, please refer to Entertainment > Media > Media Format in this manual.
• Then check if there are problems with TV.
a. Make sure the memory is sufficient. If the memory is full, clear cache and play the file again.
b. Make sure the cable connected to the TV and the external device is not loose or disconnected.
