After 5 to 7 minutes of playing, we get loud static. What board is involved. It seems to be coming from the right side of the piano. Would love to have name of someone in the Sarasota Fl area who knows boards and can fix.....or do we buy the complete board....if so, from where??

CVP 209 problems
by: Clavinova fan

Jared - do you still have the old DM board? Sounds like you should be careful about further investment before being clear what is wrong. It should be possible for a competent tech to diagnose the problem much closer than you have experienced.

Telmar, same comments really but have you done all the obvious checks - midi in/out, etc. The Aux in just drive the analogue audio so does not prove anything other than that.

I have been through the fire with a 209 and have it working after a fashion - now know too much about the inner (not)workings!

CVP 209
by: Jared

£5500 10 or more years ago & now this beautiful piece of kit is knackered!! First the left channel stopped working & then almost two years ago right channel stopped working. Have had a guy for over a year now trying to fix it but he's just so unreliable atm. First it was definitely the mother board well over £2000, but then when he changed that still the same & now it's the power supplies to each Amp, the left & right have a separate power supply. This he said was going to be an easy cheap fix £70 plus labour. haven't heard from him for months but now all of a sudden another £1800 not £70. I have studied electronics & can repair any mobile phone screen going so how hard can this power supply replacement be please?? Is it simply plug & play? Are they just self contained units that can be taken out, unplugged & replaced? How easy to source please? My son will be home soon from 2yrs Christian voluntary work & will be going to Uni. He needs this, my wife needs this as she teaches Piano to friends for very little money. The CVP served my son well he got an A star in GCSE & an A at A Level music with the aid of our trusty CVP 209. Please help???

Repairing CVP-207 Circuit Board DM
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?

Request the parties to Yamaha of Japan.

Find your Yamaha dealer and request the parties to Yamaha of Japan.
Only they have the specific parts.

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?

Successful repair. CVP-207 has regained its luster and sound


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.

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?

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

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
