Hello guys.

i have one Yamaha C3L-PXP Grand piano, i bought it from Japan, the problem is while i want to assign pocket controller to my disklavier piano, the Standby/ON button is flashing, and never stop Flashing, in this vase i called YAMAHA in USA, and ask them about this issue, the technician guy said, 99% the problem is from the Hard Drive of your DIsklavier, also he gave me the Part number to purchase this Item from Yamaha, but the problem is i am Not sure if the problem is from this part.

does anyone knows how to solve this problem?
