Troubleshooting

Backing Keyboard BK-5

The external screen remains dark.

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 flicker in the television 
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.

—

Can’t see the edge of the image on the television 
screen

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.

—

Lyric display is wrong.

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.

—

Insufficient volume from a device connected to 
the BK-5’s AUDIO INPUT (STEREO) socket.

Could you be using a connection cable that contains a built-in 
resistor? Use a connection cable that does not contain a resistor.

—

—

The songs won’t play.

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.

—

No Performance Lists are displayed.

The USB memory doesn’t contain any Performance List files.

—

For some reason the USB memory is not recognized.
