Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

Hi all.

On a Trident MKII all the preset section leds will light up
constantly when the sytnh powered on, and no signal is heard when
playing… If I disconnect the computer board from the circuit,
then I can play the string section, but not the Synthe section (no
sound)… The brass section in this case seems to make some noise but
do not function correctly (I get very short fast attack notes…)

The battery was replaced before with a nicad 3.6v 300ma one, so I
don't know about previous case of battery leakage,
although I did see a very few black traces near the battery area,
and cut them and retraced them. all components on that area look fine
visually so I didn't replace any of them.

Also, I can see a few partially black traces on the KLM-379B board,
right at the place that is below the battery.

I do not know were to start in this case as visually the components
and boards visually look fine.

Does anyone have any advice ?? Anywhere I can have the Trident
schematics from ?

I appreciate any help !!
