Disklavier

Hi all,

I am new to the group and this is my first post. I have a pretty 
high level of technical skill when it comes to piano action work, 
tuning and voicing, but I am new to Disklaviers.

I have a 1990 C-3 Wagon grand from japan that I picked up very 
inexpensively and after having done a little regulation work (very 
minor did'nt need much even though its 17 years old! Go Yamaha!) and 
some voicing (was a bit bright, now sounds like a mason and 
hamlin) , I would like to run the automatic calibration on the 
disklavier unit as I am sure it hasnt been done in a long time.

What is the sequence to get the unit to "boot" in to maintenance 
mode?

The menus are in Kanji, but I have a close family friend that is 
japanese to translate so I should be able to get through it.

Any help would be appreciated.

Thanks,

-C

Hi,

to get into the maintenance mode, hold down both SONG SELECT buttons ( |<< & >>| ) while powering up.

Press (+) 5 times to get to "KEYBOARD MEASUREMENT".

Press "PLAY/PAUSE". It should say "ARE YOU SURE?

Press "PLAY/PAUSE" again.

The piano will start playing by itself. While it does so (15-20 mins), don't touch the keys, whatever you do. It will then calculate the piano tables. Once it is finished, it will come up with "OK" (if you're lucky) or it will show "PASSxxx)", which indicates that there is a problem with one or more keys (xxx indicates the key number).

You can compensate for individual keys by following the above procedure, but only press the (+) button twice to go to "KEYBOARD ADJUSTMENT". The piano will then start playing a chromatic scale. When it gets to the note which is causing problems, press the "PLAY/PAUSE" button. You can then use the "R" button and the "L" button respectively to increase or decrease the velocity.

If you find that the pass numbers indicate a continous range of keys, rather than individual ones, you may need to physically adjust the sensor rails. At this stage, it might be best to get the service manual and the maintenance manual to give you mor details, or call your local Yamaha service/tech support department.

Compared to later Disklavier models, you have picked the most difficult model as an introduction to the Disklavier. However, if the regulation is up to scratch, it is possible to get these pianos working OK, it's just a bit fiddley and time consuming.

On another note, if you have electronic problems with the original (Wagon Grand) disklaviers, Yamaha in Japan are getting to the point where electronic spares are no longer available (this series was discontinued in 1992)

Hi,

Can anyone recommend a Disklavier technician in Sydney, Australia?

Many thanks,
Peter

Thanks Budd, I'll give them a call.

 

It's an HQ100SXG, originally from Japan.  I think it's the equivalent of
a MPX100 XG -  at least it's compatible with the Mark II XG firmware.  

 

I am pretty sure it is an electronics problem. On silent mode or midi
out, C5 works fine on power-up, but stops firing after a minute or so.
If I turn it off for an hour or so it works again for a bit. Has anyone
else had this kind of problem?

 

Cheers,

Peter

Hello

I live in Melbourne and the only chap I know who dables with Disklaviers
is Barry Nottingham , Try 0407927718. He is a Piano tech but I guess you
can ask him

There is a chap by the name of Ted Ramus and is in Melbourne. I am sure
you can ask him and he will put you in touch with a chap in Sydney.
ted's no is 0418 541819. He is ex- Yamaha and even Yamaha still consult
him. He once fixed my HS8.

Second option is to contact Joseph Pentacoso  at Yamaha Melbourne who I
believe is in the repair and service. Just use the white pages to find
Yamaha Melbourne no and he would help you.

What type of Piano is it that needs your attention? What is wrong with
it? If it is a small menu problem I may be able to refer to my reapir
manual as well.

Good luck and all the very best.

Budd

Sorry for coming in a bit late on a reply. I'm catching up on the 
changes and will be subscribing to the new Google group. 
I've got a couple of people you could try. I been using Greg 
Chamberlain to tune my DKS. Ph: 02-9679 9332 or Mobile : 0414 461 
716.  He's had training with Yamaha and  he's been tuning my MX95. I 
haven't had to put him to the test as my Piano has been trouble 
free. The othe person who I know is very experienced in disklaviers 
as he had their agency in NSW for quite a while is the owner of " 
Theme and Variations" , I can't think of his name, ( I think Ara is 
his name, he's the owner and does all the Piano Tech work for the 
Con)  ) Their showroom is at St.Leonards, on the Pacific Hwy between 
Greenwich Rd and Bellevue Ave. These are the people I purchased my 
Disklavier from  a few years ago and Ara knows his stuff. He lost 
the Agency from Yamaha when he ran with Steinberg the opposition. 
Hope this helps.
Cheers.
