So you can access TE-BOOT (holding COM when switching on)?
Try updating the firmware.
Thanks. Nope, can’t do anything. When I turn it on, it just turns white like that.
If you boot up normally and hit the synth button, can you hear some tones when you play the keyboard?
So if I turn it on with the USB cable plugged in: nothing happens if I press any keys.
What exactly is “a while”? Some seconds? A minute?
OK, yeah I’ve only had it a couple days so I’m returning it.
Hey, did you manage to solve the problem ?
I have the same issue !
