My friend accidentally connected it to a 220V Outlet (My keyboard needs only a 110V btw, so it has its own transformer.) After that the Keyboard didn’t work. I was planning to buy a replacement for my DC Power Supply, but before I do, I really need to know what’s broken. Can anyone please answer, I would really appriciate it. Thank you!
