Keaboard given too much power
I have an M-Audio Code 49 keyboard and the other day I accidentally plugged in a 12v instead of a 9v power supply. The lights on the keyboard flashed a bit and then went dead. The keyboard no longer turns on. I opened it up to have a look at the circuit board to see if anything was obviously fried and I couldn't really see anything but to be honest I don't know a lot about this stuff.
Es esta una buena pregunta?
