> Hi , I dont know much on how to help you with your tech problem. Im in Nice and I investigated a couple of years ago about getting a disklavier technician to check on my piano. It was very difficult to find any. Yamaha France directed me to some piano shops selling the disklaviers ... the ones i contacted refused to give me reference tech since i had not bought my piano from them !!!

Hi. I have this exact problem with my MX100B. The LCD shows squares on the top row, the display shows 00, and nothing else is responsive. I also have LEDs 1-6 on, while LED 7 is off. 

Were you able to resolve this problem? And if so, can you share what the fix was? Thank you.

Does the 8 piano checks work after entering the test program?  
See the group’s photo .test MX.

The keyboard thermostat may be dead, had there been any abnormal movement before it broke?

I cannot enter test mode. Holding the L and R buttons, and then pushing the power switch, don’t do anything. The number display remains at 00 and pushing + doesn’t change a thing. 

What do you mean by the group’s photo .test MX?

Where is the keyboard’s thermostat?  There was no abnormal movement when this error occurred. The player simply stopped playing music all of a sudden. 

I don’t know if the issue I have is due to failed capacitors (all of them look okay; no bulge), failed fuses (two fuses are they’re in tact), or something else. Again, the system turns on, but the LCD is nonsensical and pressing buttons doesn’t do anything.

That model Disklavier was before memory so there are no built in test or maintenance modes.  Try a new LED.

This was so long ago  ....  

Parts aren't available for the MX100 as a general rule.  The last MX100 that I worked on had a bad disk drive.  I tried cleaning it but perhaps I didn't leave the cleaner disk in there long enough.  I sent the power supply in to have it monitored but it came back fully functional after a 24 hour observation time.


The MX100 II I worked on recently had an all green LCD display.  I replaced the display and installed a small circuit board that the owner ordered a long time ago for a failed record feature.  Once both these items were replaced the piano worked perfectly.

My statement was wrong.

MX series I/o board LED lighting routine.

Main power switch On=all led On.(other than 7 Led.)
Control unit power switch On(no disk)=all Led On from all off.(other than 7)
Disk in=all Led off.
Disk out=all Led on(other than 7)

Please check wiring about external midi connector box and power unit voltage.
Power unit connector 
PIN number 1=+5v
2=+5v
4=+12v
8=+5v

I have I/o ,cpu board and others too.

Thanks for this information. I’ll check voltages on the connector and report back. 

I don’t think the LCD is defective since it lights up. It just doesn’t show anything meaningful. 

On the I/O board, it seems to me that LED 7 serves no purpose at all, since it’s always expected to be off. Is this correct?

I don’t believe the system on the MX100B can be swapped our completely in lieu of the DKC 850. My understanding is that these have to work together through the MIDI ports.  So if my system is faulty now, adding the DKC 850 won’t help. :-(

Thanks for this information. My guess is that the LCD display is functional, but related circuit board may not. There’s another post in this thread with possible parts, so I may go the route of obtaining them.

Good afternoon, everyone.

For reasons that have not been explained, Yamaha does not recommend the DKC-850 for the MX100A/B, Wagon Grand, and MX80 systems. However, if MIDI input and output are functioning on these systems, the unit can be set to work with them by connecting with MIDI cables, following the same procedure that is used with the Mark II.

Starting with the Mark IIXG (and any Mark II that was previously upgraded to the Mark IIXG), the DKC-850 can be set up as a complete replacement unit for the existing control unit. From a user interface perspective, the DKC-850 control box provides functionality that is essentially indistinguishable from what you get with an E3 Disklavier. Of course the DKC-850 does not update the hardware in the piano. For example, it does not provide a silent system for pianos that did not have one originally. Regrettably, the DKC-850 does not support the high resolution recording and playback of the Disklavier PRO. So, when used to “upgrade” a Mark IIXG PRO or Mark III PRO, you simultaneously downgrade the “PRO” aspect of the instrument.

Using the DKC-850 as an upgrade for a Mark II or Disklavier earlier obviously extends the functionality of the earlier instrument. However, you do have the awkwardness of contending with 2 control units: the original and the new one. Because the old and new units connect with MIDI cables, you do not get access to DisklavierTV or DisklavierRadio since Yamaha does not permit data from those services to be transmitted by the MIDI Out port.

Regards,
PianoBench

Correct.
If the thermo is dead then Led 7 is on.

MX series does not accept MIDI signal unless the disk drive is normal.
