Discussion about the Korg PolySix synthesizer

Hi
I know it's the polysix group but there's a lot of tech people around who
could possible give me some clues...
My Poly 61 at start up freezes with the initial message "PS 61" in the
display.
I replaced the internal battery, but the malfunction continues.
I replaced all the boards with one other damaged Poly 61, except the CPU
board.
I also replaced the 2 chips CPU IC - 8049 from other CPU board.
Can't replace the CPU board because the other one I have is corroded by a
leaking battery...
This take me to conclude for a damaged CPU board (KLM 509 - new production).
Am I wrong?
Does anybody have any suggestion?
Do you have one of those in stock (KLM 509)?
Let me know, please.
Thanks and best regards.
José

Have you checked the IC and cable contacts ?

Hi Gil
Thanks for your question!
I replaced both CPU ICs from the KLM509 board with two from my other POLY 61
and checked the cables which seem to be OK, but the POLY61 keeps freezing at
start up...
I have the service manual but there's no test descriptions for the CPU
Board...just for the remaining boards...
Best regards
José

Hi,

The CPU board is a safe bet ...
I would check the following (in this order):
1) Power supply. There is an adjustment/check procedure given in the
service manual. Do this.
2) Reset circuit of IC30.
3) CPU activity e.g. on ALE (pin11 of IC30).
4) Continuity of PCB traces around the NiCd battery. Electrically +
optically. I bet that they used the same brand and make as in the
Polysix...
5) Check for good voltage levels on CPU data/port lines (ca. 0V /
ca +5V, nothing in between).

In my copy of the schematics there are a few components around the
RST circuitry changed or eliminated manually. Do you have this?
(R145, D12, C53 (or is it C55, C33 ? - cannot read it...) are striked
through; R146 is 2K2)

Do you have access to an oscilloscope?
Where are you located?

Good luck,

Johannes

Hi Johannes
Thanks for your kind answer.
1) I checked the power supply and the voltages are Ok. 15VDC, -15VDC and 5
VDC.
2) I'll do that, though when I ground pin 4 (reset) on both CPU ICs seems
like the POLY 61 initializes.
3) I'll also do that.
4) I checked PCb traces carefully both electrically and visual. Everything
seems OK. There's no great damage from the leaking battery. I also
resoldered some points in the PCB specially on connectors and resistors,
which seemed less trustable.
5) I'll do that.

I have to check the diagrams to look for the changings you refer.
I don't have an osciloscope but I think I can get one borrowed.
I'm located near Lisbon.

Best regards
José

Hi Johannes
1) I checked the power supply: 14,99 VDC, -15,03 VDC and 5,04 VDC
2) I don't know what is the Reset circuit. When I "ground" the RESET pin on
IC30 the poly61 display clears and return to the "usual" PS61 message.
3) How can I check the CPU activity at pin 11 of IC30?
4) Rechecked all PCB traces around NiCd battery and everything seems OK...
5) I checked the voltage levels at IC30 and IC1. Both have 4,98 VDC although
the voltage at the entrance of the board is 4,98 VDC. Remaining IC in the
CPU board have 4,99 VDC. Are these deferences significant?

In my schematics there's nothing striked or changed.

Thanks for your incoming suggestions.
Best regards
José
Portugal

I don't know the P61 but does it have sockets for ICs ?
If so have you tried to tighten them in their places ?

Hi Gil
Yes, I did.
The CPU chips are assembled in sockets. I even replaced the chips...

Hi José

I don´t know the Poly-61 and how he is organzied, but maybe the
"PS61"-Messsage is not generated by the CPU Chip, so -maybe- the CPU
itself doesn´t work cause of a bad connected (overall defect/missing
"ground-line") main Oscillator (which feeds the main CPU)

Pure speculations.

Greetings

Stef

Thanks Stefan
I also replaced the oscilator board KLM-508 with one from my second
Poly61...No good results...

Hi José,
i try it in your language (thx to google :)

Eu signifiquei a unidade, que fornece o processador central com o pulso
de disparo (normalmente uma unidade preta). Este componente é necessário
de modo que o processador trabalhe. É possível, isso que é soldado
completamente perto no processador central.

I hope you can understand what i mean :)

Greetings

Stef

Hi José,

i mean the Oscillator which is connected to the 8048/8049 CPU directly
(not the Oscillator Board). It must look like that:

www.phasereffect.com/img/osc1.jpg (Picture was taken from Oldcrows,
sorry, i don´t have a Photo of my KLM´s nor a Camera at the moment).

My opinion is: If the "PS61" message is really -not- generated by the
CPU, then it could be possible that the CPU doesn´t work cause of this
component.

Stef
