Got a Panasonic CD stereo system SA-AK410 When I turn it off after a few seconds it turns back on. Is this normal?

That's because you haven't set the clock on the system. I jumps to DEMO mode once you turn it off without the clock set. Clock can be set through your remote. Hope this helps. Cheers.

Thank you, momodesign! Although this discussion is seven years old, it really helped me!! I bought and just received another remote from eBay (mine was ruined by old exploding batteries). Your solution totally worked! For $9 I now have my audio system back!! Woo hoo!!!
