Disklavier

With great anticipation, I have received my "new" MX100 II and it 
looks and plays beautifully!  Thanks to the info here for getting me 
started on converting the midi files of old reproducing piano rolls 
to Disklavier format.  The procedure is painless and the music is 
wonderful.

I did have a problem in that the contrast on the LCD display was so 
low that I could not see ANYTHING on the screen.  Upon really close 
inspection with the room lights very low and looking at just the 
right angle, I could just make out "Insert Disk."

Do any of you have a similar problem?

I have a technical background in electronics and armed with the 
technical service manual from Yamaha and my test equipment, I 
diagnosed the problem to the display itself.  This, I thought, was 
odd in that I have never run into a display which faded to nothing 
over time.

In checking with the Yamaha technical staff, I found out that this is 
not too uncommon for a display over 10 years old.  I ordered a new 
display module, installed the unit myself (about 1 hour of very 
careful work)and...problem solved!  Works like new!  Well, it is new, 
the display that is.

If you are suffering with a very light display, you may wish to 
consider having your display replaced.   The part is about $230 plus 
the installation time for your technician.

I have nothing but good things to say about Yamaha technical 
support.  Every contact with them has been first class.

Mike,  

I realize this is a very old message you put into Yahoo Groups.  
Nonetheless, I'm hoping you are still here...

I have rec'd an MX100 II recently.  While the control unit (player) 
operates fine (plays disks and midi in), the LCD screen is totally 
blank (like you described).  However, my LCD screen is all lit up 
(green) but without any text.  Is this similar to what you 
experienced?

Unfortunately, I cannot use any menus, record, etc. on the player 
itself until I resolve this issue.  Any advice or information would 
be appreciated.

Thanks!

Glad to hear my post has helped someone else!  Yes, the display will be lighted but no text visible unless you get the view angle just right and then it is only a "hint" of text.  You will need to have the display replaced.  I do not know your technical background but it is not that difficult - two connectors if I remember correctly and a bunch of screws to get at it.  If you are not confident in this type of work I would seek professional assistance.  If you are in the Chicago area, I could help you with this but otherwise you will need some assistance locally.  You can order the part as described in my original post from Yamaha Disklavier technical support. Freddie at Yamaha technical support can help you with this.
 
Best Regards,
 
Mike

Is there an LCD contrast adjustment anywhere on the control unit?

LCDs usually don't just completely *fail*.  The problem might just be
that the contrast somehow got turned all the way down.

Mark

Mark, 
 
No, there is no contrast adjustment you can turn but their is a voltage divider network that supplies the contrast voltage to the display.  On my unit, this voltage was correct however, I even cranked it up a bit by changing fixed resistor values (I have the Schematic diagrams and an electronics background) and it did not help much.  It was indeed the display as odd as that may sound.  
 
I have a feeling that if the display was near a window perhaps with sunlight shining on it over long periods of time, the LCD can fade due to the affects of UV.  Other than that, it might be an aging problem with the display but in any event, the display needed to be replaced and once it was, operation was and still is totally normal.  
 
Having said all that, there is always a possibility you have a different problem but that is where the expertise of a skilled technician would be helpful.
 
Best Regards,
 
Mike

Hello Mike and Yadidisklavier,

I am from switzerland and have an MX100II. 
I disconnected the main plug of the piano while my holidays. When I
come back two weeks later I switched on the piano. Then I noticed that
there was no text on the display. Not nice.
The backlight was ok. I tried to check whether I can see any dots of
the character matrix by changing the angle of view but there was
absolutely nothing to see.

I'm interested how your (Yadidisklavier) display was repaired.

Bernard,
 
If you read down further in this post, you will see a copy of my original post re: the display.  Having a background in electronics, I was able to test and replace the display myself.  It is not that difficult for someone who is trained in this type of work.  I recommend you have a technician look at the unit if you are not familiar with this type of repair.  
 
My display was blank from the moment I purchased the piano from the previous owner so I do not know how long it was blank or if it went blank suddenly like yours or faded over time.  
 
Thankfully, parts seem to be available.  Nothing beats a working display - - accept, of course, a working display and a delicious piece of Swiss chocolate! 
 
Regards,
 
Mike

Great info. Thanks for the replies.  

I'm not exactly in love with my local "official" DKV service option.  
I am mechanically inclined with electronic devices and with tools.  I 
don't have the know-how to test.  I wonder if I could remove the 
display and possibly have Yamaha test it for me.  Any thoughts on 
that before I call Yamaha and embarrass myself?

Thanks,

You'll find that due to the cost and space requirements, nobody (even most Yamaha susidiaries themselves) keeps test beds for Disklaviers. This means that it would be virtually impossible (i.e. not economically viable) to test individual components without access to the piano which the part originally came from.

Do you mean that someone with the appropriate bench equipment couldn't 
test the inputs of the display for function?

Mike,

Do you happen to have the old display still in your possession?

Yes, I have the old non functional display.  
 
It is very difficult to test the display without the supporting circuitry of the controller.  Try this, at night, in a dark room, turn on the Disklavier in the normal way without putting in a disk.  The display should, after about 10 - 15 seconds, display "Insert Disk"  See if you can see the individual pixels of the display - if you look very carefully, you may be able to verify that there is a very very faint display of the "insert disk" text.  If you can see this, and if it changes when you do insert the disk, there is a strong possibility that the display just needs to be replaced.  If you do not see this, it does not mean the display is OK and the problem is elsewhere but that could be the case.  The easiest way to determine the problem is to swap the display with a known good one or put your display into a known good controller.  Where are you located?

Mike

I'm located in Bethlehem, PA (eastern PA).

I'm wondering if I could get enough information off the display and 
find a substitute.  While I'm sure Yamaha would sell me one, I would 
hope to find one on the secondary market.  Any chance of you taking a 
digital photo? 

Also, I can't make out any text with the lights low.  The green 
backlight is bright, but nothing else.  The player, otherwise, works 
great.

Greetings n9544c,

I am not familiar with the construction of the Yamaha display but I
have fixed several LCD displays. I assume that this is an LCD display
because "backlighting" was mentioned. The most common problem I have
found is the interconnection between the display and the driver. The
type that most often has this problem uses a conductive rubber strip
(an array of isolated conductive fibers)) between the driver board and
the LCD panel. Some of these (the newer ones) are sealed against
moisture with a special compound but the older ones were often not
sealed. They can fail if moisture or dust gets between the rubber and
the LCD panel. They can also fail if the feature that insures the
mechanical contact fails or if the rubber looses its elasticity. I
have fixed some of these displays by cleaning the rubber (no
fingerprints after cleaning) with 99% isopropyl alcohol and
reassembling them with shims (if necessary to insure a good contact).
It is best, however to replace the rubber conductive strip with a new
one if you can get it. I had fixed the LCD display on my Fluke
multimeter several times over the years. It would work for about a
year and need another cleaning. I then discovered that Fluke (I doubt
that Yamaha would do this) sold a rebuild kit for about $5 that
included an upgraded conductive strip. It is still bright and missing
no segments after 3 years.

In terms of replacement with a generic display: If there are dense
blocky special characters or symbols, it is possible that it is a
custom display but if it is just a pixel array, it is likely that it
is a stock part. There are some very common displays and you might be
lucky and find that Yamaha used one.

Hi, and yes, the type of display and repair you describe is absolutely correct.  I have also made this repair to my own Fluke 8060A!!  However, the display in the Disklavier is of the integrated intelligent type as sourced by Optrex and others with a sealed display module integrated onto a board with smart microprocessor controlled driver software.  In this way, the user (Yamaha) only has to send codes to recall the proper characters which are generated within the unit itself.  These smart displays are not expensive as an OEM replacement.  Usually about $75 for a two line twenty character display.  The problem is finding an exact replacement which is another matter.  And again, the Yamaha part is about $250 dollars which is reasonable considering your time spent on trying to find a substitute without risking damage to the controller.
 
Regards,
 
Mike

I will photo for you this weekend and if I can find any markings, I will note them in the email.  Please see my other post.  I have also thought of finding a replacement but after about half an hour with some vendors catalogs, I concluded that the Yamaha replacement was the safest, fastest, and most cost effective solution for me.  
 
In the darkened room, you should be able to see the array of pixels that make up the two lines of text in the display even if they are turned off.  Did you see this?  You need to identify these first to see if you can see any characters faintly on them.  I know this is very difficult.  It's one of those things you cannot see unless you already know what you are looking for. If these characters are changing, then the display controller is working and it is a no contrast issue as described before.  In my case, a new display was an instant fix.
 
Regards,
 
Mike

Check out the new AOL.  Most comprehensive set of free safety and security tools, free access to millions of high-quality videos from across the web, free AOL Mail and more.

You are great...thanks for doing this.  

I'll try looking at the disply again to see if I detect the array of 
pixels.  What you say about "already know what you are looking for" 
is making sense.  Its like those "seeing eye books".  I'm sure I'll 
need glasses when all is said and done.

very difficult.  It's one of those things you cannot see unless you 
already know what you are looking for. If these characters are 
changing, then the display controller is working and it is a no 
contrast issue as described before.  In my case, a new display was an 
instant fix.

$74 dollars later....the LCD problem is diagnosed.  It seems that 
some components came loose off the LCD board.  Because the board is 
printed circuitry, there isn't a chance of reattaching and the 
technician tried to call Yamaha today for a replacement.  Yamaha 
wasn't open today..."carpet holiday"...what the heck is that? 

MIKE - it looks fairly simple plug-in procedure.  Do you recommend me 
going the distance and having the tech install the new board?  I 
really hate paying someone for something I enjoy doing....keeping in 
mind I have already paid him to diagnose.

If the control box was removed and you could see how that was done and if you can see where the two cables from the display were plugged in then you could try it yourself. The replacement display is simply mounted like the old one and the cables plugged into the same connectors being careful to install the connectors in the correct orientation. This assumes that the display was definitely at fault and all that is required is a new one.

lol - you're last sentence...thats my dillemma.  Even though the tech 
diagnosed the display as  being bad, I could very well get a $250 
display and find out there are other issues to diagnose.  I think the 
fact that there is a component (looks like a very small transistor or 
diode)with a broken lead, was how he made the diagnosis.  Sounds more 
like an assumption to me.  

The board looks easy to take out.  The hardest part being the metal 
twist fasteners holding it in place.  

I'll just let the tech do it and hope this doesn't get any more 
expensive.

Thanks,

Geoff

DO NOT REMOVE ANY TWIST FASTENERS !!!
 
THe entire display comes as a unit; display itself, and PC Board permanently attached!
The display will come out in one piece.

Thanks for the head up.  I'm guessing I would have figured that out 
when I looked closer.  Nonetheless, thanks.

Heres the rest of my story:  The tech called me yesterday and told me 
that Yamaha said these displays are on back order until June 2007.  
They've had a rash of replacements recently!  And "it seems that 
these are subjected to age failure".  $260 plus $100 labor, on top of 
the $75 labor (already paid) to diagnose.  Jeez, at least I have time 
to budget for it.

Remember, if you are not already doing this, the Mark II can accept MIDI data directly and a program like Van Basco can be very helpful and fun in organizing music to play on the Disklavier while your display issues are worked out.

Check out the new AOL.  Most comprehensive set of free safety and security tools, free access to millions of high-quality videos from across the web, free AOL Mail and more.

I'm doing the laptop thing....I have been working at it for some time 
now, editing and categorizing whatever midis I can get my hands on.  
I use Sonar (had it already from a recording setup) and the Van Basco 
software, which is great for setting up playlists...especially when 
there is Karaoke involved....the kids love that.  The player still 
works with 3.5 disks as well, so I'm not at a loss.

Now I'm getting intrigued by having some of the midi files, that have 
drum tracks, etc., play out of the sound card while the DK plays the 
piano.  However; I need to research some of the posts here to figure 
out the best way to deal with the latency issue...drums not syncing 
up with the music.  I think I've read about the Karaoke not syncing, 
and I know that Van Basco can deal with it.  I just need to figure 
out how to do it with the GM sounds from the sound card.

It seems that your drums are on the sound card of the PC. This means that your DKV has not other internal sounds, just piano. You may be are seding MIDI out to

Hello yadidisklavier,

good news: Today I could repair the LC-Display of my MX100II
successfully. I just used our disklavier for recording my daughter's
piano piece "Brasilian flair". 
Diagnose: One of the two caps (4,7 uF , small black cube) was bad and 
so chemical agressive liquid run out. So a conductive strip was
corroded and the result was a gap in the strip.
I bridged the gap and replaced the two caps.

Maybe your display has the same defect. To check this you only have to
bend the two caps in order to can see the stips. Then use a magnifying
glass to check them.
You can also measure whether strips are broken.
If you have an expert for electronics he can do that for you.

I hope I could give you a hint.

btw: Electrolyt caps often fails because of run out liquid or dry out.
That's a known problem. After 20 years of lifetime all electrolyt caps
could be checked and replaced as a precaution if wanted.

That is good news.  One of the caps on my board is actually 
disconnected from the board (hanging by one wire).  My thoughts was 
that the solder joint broke during one of the shipments of this pians 
(I'm the third owner).  Because its such a tight area to work with 
(soldering), I was thinking about removing the board carefully and 
bringing it to someone with the tools and experience.

How did you find removing the board?  Challenging?

For me removing of the board was not complicate. This depends on your
own personally experience with such things. To remove the board you 
only have to loose appr. 20 screws, two connectors and some cable
binder (I don't know the right word). Repairing of the corroded solder
strip was a little challenging cause of the very small dimensions.

My odyssey has finally come to end today....  I ponied up the $380 
and had the display replaced by a technician.  There was a capacitor 
with some broken solder connections.  I purchased the piano used 
several months ago (everything worked).  My theory is that during the 
move (Piano Moving Inc.), the piano most likely was shaken and the 
soldered joints simply broke.  I think its important to note this 
because I wouldn't want to give anyone the impression that these 
boards just up and die (piano is over ten years old).

Thanks to all who have messaged on this topic!

C O N G R A T U L A T I O N S ! and enjoy your new display. 
 
 It was money well spent and there could have been other problems internal to the old
 display that you did not see. None of that matters now because it is new and 
 probably has a warranty!

 Subject: [disklavier] Re: MX100 II Main LCD Display Problem and Solution
 
     My odyssey has finally come to end today.... I ponied up the $380 
 and had the display replaced by a technician. There was a capacitor 
 with some broken solder connections. I purchased the piano used 
 several months ago (everything worked). My theory is that during the 
 move (Piano Moving Inc.), the piano most likely was shaken and the 
 soldered joints simply broke. I think its important to note this 
 because I wouldn't want to give anyone the impression that these 
 boards just up and die (piano is over ten years old).
 
 Thanks to all who have messaged on this topic!
