Press the last note (right side) while powering your s700 ,this will reset your settings.

change the whole screen the on capacitor 344 & 544 add resistor with value 2.2k, it will help your keyboard stay longer.

It sounds like one of the OTS buttons is getting triggered accidentally. There may be a build up of residue behind the button. With the unit off, try rapidly pressing the OTS buttons, one at a time. This should help to move any debris which may be creating a false contact.

If you are feeling brave, you can try opening the keyboard and getting inside, under the button with some electrical contact cleaner such as DeOxit or Servisol.But be warned: it can be difficult to get the parts back together properly! So if you don't have much servicing experience, call your local music shop to find a service technician.

Well first start by calling or emailing the manufacturer. They'll let you know who distributes their parts or If it's still available or not. But also could be a power supply problem.

Likely a connection to the backlight is being broken. Tap on the unoit and see if it pops back on. Illuminate screen with a flashlight and see if the characters can be seen when screen is faded. If they can, then the backlight is the problem... IF NOT then the display may be bad... This has been a problem and if you are under warranty, excersise it immediately... else replacement of the display is relatively expensive.

You MAY be confusing touch sensitivity with VELOCITY sensing. Touch sensitivity is PRESSURE put on AFTER the note sounds that causes modulation. VELOCITY is what is used for example to control the loudness of pianoo notes depending how fast they are struck. VELOCITY sensing is done by using TWO contacts at every key... one closes first. IF one of these gets dirty, FULL velocity will be sensed and it will be LOUD. The contacts can be cleaned using ONLY 99% isoprophyl alcohol and Qtips after MUCH disassembly of the keyboard. The contacts are conductive rubber pills in silicone rubber domes. Clean boththe contacts and the circuit traces they pres down onto.

Usually that is caused by corrupted software. Try reloading the firmware. https://europe.yamaha.com/en/support/updates/firm_psr-s950.html

Seems the carbon layer under the button needs repair.

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!
