Hello there !
My name is Shah.I bought a Yahama DGX 640 digital piano in Feb.2013 and I have been learning piano since then. Very often I face many problems with the key board like some of the keys don't work sometimes. However, turning off and turning on again after sometimes automatically help it works again. Recently, two keys F and B along the keyboard of 88 keys are not playing or creating any sound but other keys are OK. I wonder the keyboard is out of order. Can anyone be a help to advise me resolve the problems of these two keys ?
Regards,
Shah
