Hi, thanks for the video, what is the exact model of the rotary switch to buy for replacement?

Hi, thanks for your videos. I've got a question for you, if you please help me. I have a Korg PA50 which I did not use it for a long time and one day decided to use it, it turned on but the display started to dim and was un readable and basically the whole keyboard became dead ( nothing worked).
What do you think is the cause?
Thanks for your help.

Hi,
If you are familiar with using multimeter please check voltages at terminals of all filter capacitors in power supply board (do this only if you know about power supplies as there are chances of getting electric shock if you touch primary section of PS). Or disconnect the device from AC mains and try to disconnect and reconnect all board to board connectors and check. only these basic things I can advice without seeing the unit. hope this would be helpful.
Next week I will be uploading a video on Yamaha keyboard may be it can be of some help for you, the device is under testing, if it works fine until next week I will upload the video.
Thank you, have a GOODTIME....
