SOURCE: Yamaha PSR-280 : AC power instead of DC power

An answer, but likely not a solution. I believe all Yamaha PSR series keyboards use the same 12 VDC adaptor, so I looked at the electrical schematic for another model I have. There seems to be no fuse on the power input. There are two components shown on the positive and negative wires off the power socket, but the symbols do not look like anything I have seen for fuses - they may be resistors. Power goes directly to a 5 VDC voltage regulator, which powers all of the solid state componenents. Too much voltage of the wrong type could have easily ruined many of the sensitive components.

Your only hope is to check the power socket area for the possibility of having fuses. My drawing shows the power socket, voltage regulator, and audio power amplifier being on one circuit board. That may not actually be the way it is in your model.

Good luck!

SOURCE: Yamaha psr-240 lights up but no sound.. no sound

try placing your ear on the speakers, adjust the volume control up and down several times, you should hear a humming sound that goes up and down. if not problem with the stage before the amplifier, that is the sound processor. if you dont hear the hum. problem with the amplifier and speakers, including the sound ports or jack. dissassemble the unit. look for loose connections from speakers to amplifier.

PSR e423. Why does it have a blank screen and no sound?


Blank screen and no sound, can occur because of damage to the power supply circuit in the PSR-E423.
Circuit power supply is still working but the voltage is not sufficient. This is indicated by a lit LCD screen but does not appear any character, and the sound did not exist. It is a matter of hardwares, so it can not be reset by software.
Should be fixed to the experts.
Do you use the original adapter? Also check the voltage.
Maybe, it is not known why, a voltage adapter has been dropped.

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.

It is shop replaceable. I have heard this is NOT an uncommon problem. You can get the parts through Yamaha America in California. Here is your service manual:

Yamaha psr-280 flashing display no key response or sound. Is it dead??


Your adapter should be a 12 volt DC delivering 2 amps (2000 ma). If the adapter is too small, you will have the symptoms you are seeing. Make sure the polarity is correct. DO NOT use the so called "universal adapters".

This MAY be due to a key contact or button that is STUCK "on".

Often this will freeze the controller.

Make sure power adapter is the correct one... underpowered or incorrect ones cause trouble.
