MS2000R 'MPUtoDSP Check Error'

[Janvier]

My MS2000R never worked and when I turn it on while pressing 'ModSequence On/Off' & 3 it says 'MPUtoDSP Check Error'.

Is there any (free) way to fix it?

Or should I just get rid of it?

Thanks

Just had a friend replace the DSP56362 chip, and that fixed it. -Looks like they have a tendancy to overheat LOL.

Just for Info, I have the same problem which happened this week end. i got my ms2k for 8 years now.
My ms2k is really slow to change program and do not generate any sound anymore..
When i launch a check with 'ModSequence On/Off' & 3', i get a DSP DRAM - data Err d01014.
i have 2 questions :
did you change your dsp 56362 ? Did it solve your problem ?

Do you think my problem is coming from the DSP too ?

thanks

Yes, we changed out that chip. As to whether that's the issue on your system, it's hard to say for sure but it would appear that since it was the culprit on one system, that it's likely (or at least very possible) that it may be on yours as well.
You might try picking up a can of freeze spray and hitting it with that. If the system works temporarily, that would mean that almost certainly that chip is at fault.

Finally! A possible solution for the MPUtoDSP error.

Where should I send my MS2000R to have this dastardly chip replaced? It doesn't look like something I want to tackle.

Thanks

I called a French korg support to ask them the question about a change of the DSP56xxx. They told me to be carefull because a microcode could be saved in the memory of the DSP.

Did you changed you ms2000 DSP by a standard 56xxx bought at freescale ?
Did you proceed in that way to solve your problem ?

Recently had t he same problem ...

Just replaced DSP56362 with a FREESCALE
Also found & reworked a couple dull solder spots
Thank heavens for hot air rework stations ....
Reloaded OS

Works like new.

KORG quoted me $397.31 for replacement board a DSP56362 costs $29.00

What do you mean exactly by "Reloaded OS"?

I've just posted a reply in another topic which pretty well covers the questions you're asking.
