How to run the Yamaha DX7s internal diagnostics

Go to the Yamaha DX7s main page

Introduction

This page is a work in progress and I haven't had time to document all the DX7s internal diagnostics yet. I'll add more information as soon as possible.

PLEASE NOTE:
I accept no responsibility for any loss or damage to yourself, any of your property, including your Yamaha DX7s, or anything or anyone else, which may arise from you following the procedure detailed on this page. You do so entirely at your own risk.

How to display the DX7s battery voltage

[THIS SECTION IS IN DEVELOPMENT AND INCOMPLETE]

The current internal battery voltage is also displayed in the initial internal diagnostics screen. The details for accessing this are shown in the following section.

How to access the DX7s internal diagnostics

The Yamaha DX7s internal diagnostics can be accessed as follows:

  1. Switch the DX7s on.
  2. Press the 'EDIT' button, '16' button and '32' button simultaneously. The easiest way to do this is to press the 'EDIT' button with one finger of your left hand and keep it pressed; then press the '32' button with one finger of your right hand and keep it pressed too; finally press the '16' button with a second finger of your right hand, then release all buttons.

TEST  V1.1 87.04
BATTERY 2.9v  OK

The resulting display shows the diagnostic test version, current internal battery voltage and status. To exit the diagnostics and return the DX7s to 'normal' mode, press the 'VOICE' button.

Running the DX7s internal diagnostics

[THIS SECTION IS IN DEVELOPMENT AND INCOMPLETE]

BEWARE: Some of the diagnostic tests overwrite internal memory, resulting in the loss of custom data. Make sure you back up anything you don't want to lose before running the diagnostics.

You can cycle through each diagnostic test by pressing the '+1/ON' ('YES') button. At the end of each set of diagnostic tests, the test version display will appear.

Exiting the DX7s internal diagnostics

[THIS SECTION IS IN DEVELOPMENT AND INCOMPLETE]

At the end of each set of diagnostic tests, the test version display will appear:

TEST  V1.1 87.04
 

Whenever the test version display is shown, the diagnostics can be cancelled and the DX7s returned to 'normal' mode by pressing the 'VOICE' button.
