You have a fault no one else has reported. There appears to be no reset procedure. Take it to a Yamaha Service Centre. https://www.google.com/search?q=Yamaha+Electone+MR+700T+factory+reset https://www.google.com/search?q=Yamaha+Electone+MR+700T+lights+flash+but+unresponsive ..

If your Yamaha PSR-2000 keyboard is turning on and the blue backlight is displayed on the screen, but none of the function keys are lit up and not responding, there may be a few different causes.

1. Check if the power supply is working properly and is providing enough power to the keyboard. If the power supply is faulty, it may not be providing enough power to the keyboard.
2. Make sure that the keyboard's internal battery is charged. If the battery is low, the keyboard may not function properly.
3. Check if the internal fuse of the keyboard is not blown, which is a common problem on electronic devices.
4. If none of the above steps work, the problem may be with the control board or the display, and the machine may need to be serviced by a professional technician.

I would recommend checking the user manual or contacting the Yamaha technical support for further assistance, as they may have specific troubleshooting steps or solutions for your model.

However, I can suggest some resources where you may be able to find the electronic diagram for your Yamaha E253 keyboard. First, you can check the user manual or technical documentation that came with the keyboard, as it may include a diagram or schematic of the keyboard's internal components. Alternatively, you can try contacting Yamaha customer support or visiting the Yamaha website to see if they have any technical resources or diagrams available for the E253 model. Additionally, there are online forums and communities for musicians and keyboard enthusiasts where you may be able to find more information or connect with other users who have experience with the E253 keyboard. I hope this helps, and good luck with your search!

It sounds like you are referring to the fallboard or key cover of your Grimmel Bros upright piano. To close the fallboard, gently push it up towards the piano's music stand until it clicks into place. The curved part you mentioned is probably the key cover, which can be lowered to protect the keys from dust and debris when the piano is not in use. To lower the key cover, grasp it at the center and gently pull it towards you until it lays flat over the keys. If your cats are causing problems by jumping on the piano keys, you may want to consider covering the piano with a fitted cover or keeping the room door closed to prevent them from accessing the instrument.

Here's what others have done to find out that info..... https://www.saxontheweb.net/threads/why-are-yamaha-serial-s-a-guarded-secret.61854/

If the on/off button on your Yamaha PSR-S750 keyboard is not working, there could be a few possible issues. Here are some things you can try to troubleshoot the problem:

Make sure that the keyboard is properly plugged in and that the power switch is in the "on" position.
If the keyboard is plugged in and the power switch is on, try unplugging the keyboard and plugging it back in to see if this resolves the issue.
If the keyboard still does not turn on, try using a different power outlet or a different power cord to see if the issue is with the power source.
If the keyboard still does not turn on, there may be a problem with the on/off button itself or with the keyboard's internal electronics. In this case, you may need to contact Yamaha for further assistance.
As for the issue with some notes being too loud, there are a few potential causes:

Make sure that the volume of the keyboard is set to an appropriate level. You can adjust the volume using the volume control knob on the keyboard or by using the volume control on your amplifier or speakers (if you are using them).
Some notes may be louder due to the way they are played or due to the settings on the keyboard. You can try adjusting the touch sensitivity or dynamics settings on the keyboard to see if this makes a difference.
If the issue persists, it is possible that there is a problem with the keyboard itself. In this case, you may need to contact Yamaha for further assistance.

It sounds like there may be an issue with the power supply to your Yamaha Electone HS5. Here are a few things you can try to troubleshoot the problem:

1. Check that the power cord is securely plugged into the back of the Electone and into a working outlet.
2. Make sure that the outlet you are using is functioning properly by plugging in another device to see if it powers on.
3. If the power cord and outlet seem to be working properly, try resetting the Electone by unplugging it from the wall and waiting a few minutes before plugging it back in.
4. If none of these steps help, there may be an issue with the power supply unit inside the Electone. In this case, it is recommended to have the instrument serviced by a qualified technician.
