Gloubi,
I believe the issue is with the static RAM (SRAM) chip. It's a $5 part. You can't get it from Korg anymore, but other people still sell them new.

I had something similar happen to me. After ruling out the battery (but replacing it anyway), the tech replaced that chip, and I haven't had that problem since. 

It's the first IC chip in the row, and it's a quick, cheap fix.

Good evening, everyone,


I'm writing my first message on this great forum, so that maybe someone could help me.
I saw this conversation while I was looking for a solution for my own poly800 MKII... I have some skills in soldering but I have been looking for a solution alone for too long...
So, when I bought it, it worked well, except the switch, working even when I didn't want it to. I opened the synth, and fixed this by soldering. Then, I reloaded all the patches, and I thought everything would be alright. I played it for some days...
However, some days later, something went wrong, as all my patches were kind of "destroyed", and I couldn't get any "normal" sound out of it... I can just hear strange and weak sounds, and sometimes even no sound...

Let me tell you what I've done so far:

- Reloading the patches several times.
- Checking the battery saving the patches (this one is OK).
- Looking for leaking or broken parts/components.

I do not know what to do, and I'm really sad because this synth was a true source of inspiration for me...

If anyone could give me a hand, that would be absolutely great and helpful!

Best regards,

Gloubi
