Locate and replace damaged integrated IC28, IC29, IC43
by: Anonymous

Hello,
Excuse my English is not my first language.
Yamaha has informed me that no DM in existence.
Yamaha always said that for 10 years would have parties. However, your warranty has changed.
The solution offered is to repair the DM. Locate and replace damaged integrated IC28, IC29, IC43: (The part numbers are: XP551A0R (2 required) and X7351A00)
There are parts for the CVP-209 but indicate that DM is incompatible with some features of the CVP-207. It's strange, is the same board and I think it would be easy to make compatible

f true Yamaha are really not playing fair with their customers.

If true Yamaha are really not playing fair with their customers.

Disgraceful that a £3000 product can be left unusable ten years into it's life with no product support. What if these ics dont fix it? What do Yamaha propose to do for us then?

Successful repair.
Very happy

My clavinova 207 has regained its luster and sound.

Thanks to the work of Mr. William Marin. Excellent Yamaha Electronic Engineer in my country.

same problem
by: ulllerich

It seems I have simular problems now. Nobody wants to repair that board (only 6 years old).
Where can I buy those 3 chips?

Repairing CVP-207 Circuit Board DM NEW
by: Ulllerich

I changed those 3 Chips, the 2 DAC´s and the OP.
The demo I started is now even with full loudness nearly unhearable but is identifiable.
The digital part therefore seems to work correctly. A test signal on the OP´s input produces a normal sound. Voltages all Ok.
So- what else can I try?
