ZOOM MRT-3 Rhythm Machine, Junk Item

This rhythm machine is being sold as a junk item.
The reason it's considered junk is likely due to issues with the switches.
Specifically, the on/off switch is unreliable; sometimes the power turns on, sometimes it doesn't turn on at all, and sometimes it displays an error screen even when it does power on.
By repeatedly turning the switch on and off, it eventually displays the normal screen and becomes usable.
It's possible the internal power switch is malfunctioning rather than the power input jack. When the charger is plugged in and the machine is turned on, toggling the charger's power on and off can cause the machine to display either an error screen or the normal screen, indicating erratic behavior.
Once the normal screen appears, the rhythms function, and the keys produce sound correctly.
We are hoping someone knowledgeable about electronics can repair it and use it.
Also, inserting dry batteries in the back and turning the switch on results in the same symptoms.
By repeatedly toggling the switch on and off, it becomes usable once the normal screen appears.
Therefore, we are selling this as a junk item.
Regarding the price, we have changed the shipping method from the usual Rakuraku 60 to Rakuraku Mercari Takkyubin Collect and have also lowered the price accordingly.
Thank you for your understanding.
