New Motherboard for a Yamaha Clavinova CVP 85A?
by Barrie Thomas
We had a new CVP 85A sent out to us here in Kenya in 1995, and it gave many years of good service. However, about two two years ago it began to malfunction, initially in the disc drive, then more generally. It has become progressively worse, and now we are suffering from similar problems as John Howard Norfolks (5.2.10). We have tried the re-set key at the far right of the keyboard, and indeed this works, but for a limited time only - like a few minutes. The motherboard has been repaired three times, but now seems to be beyond it. The technician thinks that a new motherboard might solve the disc drive problem as well as everything else. The climate in Nairobi is warm and dry, so excessive humidity cannot be the problem, but something seems to be corroding the motherboard. Are motherboards still available for the CVP 85a, and if so are they available in an up-graded form, i.e. able to run a flash disc through a USB instead of the disc drive? How can we get one? We have tried to contact the Dubai office of Yamaha, responsible for Africa but to no avail. Does anyone have a contact at Milton Keynes?
