9000 PRO: HARDWARE FAILURE CONFIRMED

9000 PRO: HARDWARE FAILURE CONFIRMED

After stressing about getting the OS updated and backup installed, no errors were corrected.
After some testing, I can confirm that the problem is due to a hardware failure:


All styles in 8 Beat work, but only these.
ALL styles I copy to Flash Directory 1 work; no matter which ones.
NONE of the styles I copy to the other locations in Flash Directory work, no matter which styles I copy.

All styles in all other locations work as they should, except Ending 3.
Everything can be used as normal, as long as I avoid using Ending 3 and use Ending 1/2 instead.

Chello. I apologise as this may not helpful.
Listed Under Factory Styles I have just downloaded 9000Pro Factory & Flash Styles.
It states that these have not been altered but are true Factory.
May give you a chance to compere with your Floppies.

Have you tried to defragment the flash memory ? As per page 74 of the reference manual ...

I would delete all the styles from flash rom, then defragment and reload the factory disks using new floppies

@Graham


I can't help you with this right now, because my original styles are packaged in a format that needs to be unpacked to floppy, and I only have one floppy that works.

But the styles you mention are posted by Gunnar 3 (Gunnar Johnny), who is a very serious person.

He ran the world's largest forum for Technics in his time, and I have used many of his posted styles for Technics, all of which were 100% original.

I would therefore believe that the styles he has posted are genuine.

@titobal

Thanks for the tip - this might work.

@titobal

I deleted everything in the Flash ROM, defragmented it and reloaded the Factory disks.
I used the floppy that I installed the OS with, because this one is OK: otherwise the process would never have been able to be performed.

Same result as before.

And if you swap a style with the Ending 3 issue with a style among the workng 8 BEAT, does the style once in the 8 BEAT flash slot work ?
Also could you upload a style file with the Ending 3 issue ?

Yes; all styles I swap to the 8BEAT flash slot work.

It is not the styles that are the cause, but a missing or corrupted address in the system, which is located deeper in the structure and cannot be restored by reinstalling the OS or available data disks.

A footswitch solved the problem.

[⚅titobal]

On the other perhaps you could check the hardware of the keyboard using the Test program, info taken from the
service manual, maybe something will raise independantly from the footswitch fix

How to enter the Test Program
[AUTO MODE]
While pressing the [DEMO], [EXIT], and [INTRO A] buttons, turn on the power switch.

[MANUAL MODE]
While pressing the [DEMO], [EXIT], and [INTRO B] buttons, turn on the power switch.

Proceeding through the Test Program
To select the program number, use the [NEXT] and [BACK] buttons.
To start the test, press the [START/STOP] button.
When the test result is OK, the LCD will display "*" before the test name.
When the test result is no good, press the [DEMO] button or [C1] key. The test program will then wait for the next selection.
