Hi all,

I got hold of the service manual for the Zero 8.
Temporary link (since januari 28th 2013):

I also uploaded it to the download section of korgforums.com, but don't know when this will be available.
http://korgforums.com/?show=1

Please keep this thread alive and post your findings, modifications, walkthroughs etc.
And post it as detailed as possible >>> Pictures say more than words alone!


I won't be responsible for any damage done by yourself tinkering with the Zero 8, use the manual at your own risk.
I'm no technician, just keeping the community alive! Smile

PS: @Moderators, please make this sticky if possible.

Hey man, thank you so much!!!
I got my 1-2 channels dead both in audio and midi mode, after 9 month of excellent work, so hopefully if will help local service men to proceed.

! Actually the channels are mute and no MIDI, but the LED's are running ( opposite to another thread on the similar issue on this forum - http://www.korgforums.com/forum/phpBB2/viewtopic.php?t=59799), so probably the block isn't dead?

May be somebody knows how to do "service reset" and it will help?



And thank you one more time for the S-manual.

I'm bumping this one, as I received PM's that the link doesn't work anymore.
I uploaded it again and changed the link in the first pst.

PS: sorry for not answering the PM's, I hardly visit these (sorry to say) very inactive forums.

PostPosted: Mon Jan 28, 2013 11:15 am    Post subject: Intricates Korg Zero 8 PSU airflow fan mod. Reply with quote

Here's my external Fan mod to get some airflow going through the unit, especially dissipating the heat generated by the Zero 8 PSU, which could be a cause for the touchpanel not to work anymore..


Zero 8 with brushless external Fan mounted on the side panel.
In my case a Sym Bang D6010V12LB.




The Fan is controlled with a universal manual voltage adjustable PSU (3-12V) This way you won't have to get annoyed by the constant airflow and fannoise (at fullpower 12V)
6V setting will do in my case most of the time, and 7.5V when I feel it's getting hot. And 12V (full power) when I shut the zero8 down and let it cool down for 5mins.




The Fan is mounted on the sidepanel (which you can remove) with 2x M4 bolts (M3 will also work, but didn't have that at that time).






I milled out a space with a multitool for the bolt head to fit in the sidepanel, so it's flushed and won't sit in the way.






I used a flat ring used as a spacer between the fan and Zero 8 sidepanel, so the fan won't hit the sidepanel.
I had to cut some excess material from the rings, as the rings I had in the toolbox were too large.

ToDo's:
- Additional internal Fan mod for better airflow, and cool air inlet
- External fan wiring needs some modification (visual aspect); Longer wires, and removal of the luster terminals.

If i have some time i will put the fan inside the mixer,
power it from the internal psu and make it temperature regulated.

Best regards

1. Can you please explain :
2. which type of fan you want to use (size, voltage, etc...)
3. where and how you fix the fan
4. from which pins you get the current
5. the direction of the airflow


thanks
