Re: [disklavier] Re: The key drive temperature is very high

2017-07-29 by Dmitry

Hi guys,

I Was able to run the system diagnostic on the PDA and it shows the E1 error for 48V on the key drive. Here is the image: https://photos.app.goo.gl/O2MdqvMGejBCcliW2

May I ask for a small help to show your image of the same screen on your device? It is in the maintenance mode, (service manual p. 101): Piano Information, Key Drive Info (2-1-3). As I see 48V on the Key drive and on the red leds are on (they state for 48V) I still expect that there are 2 lines of 48V and that what the test shows as 0 as the first place before the comma on the screen.

Appreciate for the help,
Dmitry

Thank you, Darren, tnmshd!
I really forgot about the video out connector. Will also look at it as I hope additional information from this may give some points to think but unfortunately it doesn't say anything about solenoids based on the description.
But I also found the LED status description in the service manual (p.122+). But it will require to open the units again. Especially the solenoid one which is a bit of a pain (the right one. I think the centre one would be even more as it asks to dismount the pedal unit and all above it)).

If you refer to the service manual it will tell you how to get into the test mode using a USB keyboard, from there you can access a lot of test information.

No.It's the way to enter I/O center test mode.
Normally you will enter Maintenance mode using PRC.
If the PRC or media center is broken, take that way.
Service manual and maintenance hand book are required for tuner.
