Hello, I've got a Korg Polysix that the battery leaked. I have fixed the traces that have been damaged, I changed the IC30/31 chips (remplaced by HD74LS08P in place of SN74LS08N). After that, everything run fine, I was happy, my polysix was fixed. But after 15 minutes playing, suddenly, the sound stop to play. And the MG led become alway ON. Since that moment, no more 'good'sound came out of the polysix, only some noises when i choose a preset, but nothing in manual mode. Anyone have any idea of this problem ? Thanks.
