Action
Did you connect it to the VIDEO OUTPUT socket?
Did you switch on your TV or external screen—and did you select
the correct channel? See the TV's or screen's owners manual for
how to select the channel that corresponds to the video input to
which the BK-5 is connected.
Are you using a supported TV or monitor screen?
Thin horizontal lines may flicker on the television screen, but this
is due to the television itself, and is not a malfunction of the BK-5.
In some cases, the edge of the image may not be visible on the
television screen, but this is due to the characteristics of the tele-
vision and is not a malfunction on the BK-5.
For some types of music files, the lyrics may sometimes be dis-
played incorrectly. Some words may be incorrectly shown outside
the screen display area.
Could you be using a connection cable that contains a built-in
resistor? Use a connection cable that does not contain a resistor.
Check the setting of the "Audio In Level" parameter and correct it,
if necessary (page 68).
The file type of the song is not one of the file types that the BK-5
can play.
It may be that the song data is damaged.
The USB memory doesn't contain any Performance List files.
For some reason the USB memory is not recognized.
