Piano, Organ, and Keyboard/NO SOUND FROM MY YAMAHA YPT-420

Question
Please help me.  I have no idea what I've done.  I am unable to get any sound from my keyboard.  I'm not a wonderful player--and I rarely play it--but the last time I used it, I don't remember having a problem.

I have a MIDI cable but it is not connected.  I don't have headphones connected.  I do have my AC adapter connected, and plugged in (normally I keep it unplugged unless playing; it has been unplugged for at least a month).

In the past, I've simply hit the "master" button (standby/on), turned the master volume up, selected a "voice", and played.  Today I can't get any sound, and in my despair I've been selecting numerous buttons...and thus may have made things worse in my panic.

I have books that came with the keyboard, and have looked at "troubleshooting" to no avail.

Please help; I've not had this problem before (admittedly, I've not played that often before...)

Thank you.

Hello Gina,  Sorry to hear about your frustration.  There are many things that can cause an electronic device to stop working.  The first thing to check would be the power supply. They do go out.  You did not mention whether there was any sign that power was getting to the unit.  Some power supplies have internal fuses which are not user serviceable, meaning they are simply not intended to be repaired but replaced, although they are easy to test.  I suggest you take the power supply to someone you know who has a voltage meter and can test the voltage output.  The voltage should be close to the output voltage stamped on the power supply's case.  If there is no voltage or the voltage is far from spec, then you will need to replace it.

Secondly, if the power supply is good, I suggest you try connecting headphones to the keyboard to hear if there is any sound being generated. Sometimes the headphone jack can cause a problem since it is designed to turn off the external speakers when in use.  Simply plugging and unplugging headphones into the jack is all that is necessary to correct a contact problem.

Lastly, contact Yamaha directly or MITA (http://mitatechs.org/public_splash2) for service
