6 stacker not responding

[W4GNIT]

I've read through a few similar topics but found nothing that's worked.

This morning the 6 stacker in my Lib finished one CD and as it moved to the next CD nothing happened, no music no warning. When i tried to select a different disc it makes a few noises then said press eject. The number flashes for a while as it tries to eject then it switches to radio.

Other than pushing buttons the only thing i've tried is diconnecting the battery to reset it but no good.

Any suggestions?

Cheers
