No more Power on piano Shiver KS-51

[AlphaCharlie]

Hi everyone!

I have an electronic piano Shiver KS-51 and after some vacation it doesn’t turn on anymore. It used to work with a 9V power line but even with AA batteries it refuses to start again.

I opened it and you have pictures of the wires that comes from the power plug to the PCB.

The DC jack for power obviously has known issues to have a zip tie to secure it.
Check the solder joints on the under side for good connection.
Does the DC jack disconnect the batteries when inserted? Check those internal connections.
Also, with no power on either batteries or adaptor, check and clean the power switch.
Do you have a multimeter? It will come in handy now if the above suggestions don’t fix your issue.
