Replace the battery or charge the battery (depending on the player model). Make sure the new battery is not damaged (even newly purchased batteries may be damaged!).

Why only 239 MB of memory is detected by the system instead of the nominal 256 MB?

A small amount of memory is taken up by system files (firmware) which control the player.

Device shows less memory, e.g. 21 MB instead of 976 MB.

Format the player after connecting it to a computer using the FAT file system and make sure there are no encrypted partitions using the software found on the CD-ROM (MP3 Player Disk Manager).

Make sure the cables have been connected correctly and press the AV button the TV remote control.

Solving problems with using DVB-T tuners
