Hello, I use a yamaha e433 keyboard which was working perfectly. There was a day the power supply to my home was very low such that it can't even charge a mobile, so my cousin connected wire to the keyboard battery section directly to light without adapter. He said the keyboard flickered for seconds then went dead. Now when connected through adapter to light it just make a hum and does not power on. Same thing with batteries. The keyboard has a fuse on the power board, could it be blown , or the whole power board..please help
