Hello Everyone,
I'm in Cairo, Egypt.
I have this problem with the keyboard.
After a performance, suddenly on power on, most buttons are not working.
The display, the touch screen and even the sound and keybed are ok. I can play and change sounds from the touch screen.
The buttons that are not working are very "random".
START button not working, but its LED comes on if I press the sync start for example and the chosen style does work with I touch the keyboard.
This erratic behavior made me I assumed it needs a firmware update maybe because of a power glitch or something.
I can't update the firmware or Factory reset or enter TEST mode because START and MENU buttons are among the ones that are not working.
It does enter test mode but I have to press the not working START to execute each test.
"While pressing keys [C#2], [F2], [G#2] (C#2 major chord) simultaneously, turn on the (Standby/On) switch"
I got that from the PSR-A3000 service manual.
The joystick is working normal with the sound but as soon as I move it, it displays the movement on the screen!
I can't find a service manual/Schematic diagram for this keyboard.
The dealer in Egypt couldn't fix it and I contacted Yamaha USA who told me that they support USA only and asked me to contact Yamaha Japan.
I did that and found their support on an application called "Line" all in Japanese!!
Now my only hope is to find help on here.
Best Regards.
