Hi,

I have a Panasonic SA-AK27 mini hi-fi system and I’m having an issue after replacing the cassette deck belt.

When I power it on:

  • The CD tray opens and shows "take disc out"
  • When I close it, the tray closes mechanically without any problem, but the display stays on "closing" forever
  • I cannot switch to any other mode (radio, AUX, tape, etc.)
  • When I turn it off, it becomes unresponsive and won’t turn back on unless I unplug it and plug it back in

If I use the STOP + TUNING DOWN button combination, I can bypass the CD mode and switch to others, but there is still no sound.

Important details:

  • The issue started right after replacing the cassette deck belt
  • The cassette mechanism is in the correct home/stop position
  • All cables and ribbon connectors are properly connected and not damaged (checked multiple times)
  • The CD tray closes properly from a mechanical point of view

Could this be a CD mechanism timing issue or a limit switch/sensor problem?

Any help would be appreciated!
