Korg Triton and Korg Trinity Loses tones/voices

Hello Gurus, I have these two korg Triton and korg Trinity 88keys which tones are not working again. If you select any tone/voices it won’t produce tone voice at all. All tones… I.e. Piano, strings, organ, brass sections, etc none of them are working.

Please what could be the cause and what is the means of repairing this fault?
Please help.

Thanks in advance.
Regards.

Korg used some rather bad connectors during this period. I had a problem with my Trinity Plus where the sound from one or both channels at the main outputs and headphones would go dead.

The connector with the red/orange/yellow shrink tube was the problem. It does not make good contact with the pins on the analog board. All I had to do was move the cable and tie it to the disk drive cable with a nylon zip tie to provide a little tension. That’s not the best way to fix a problem like this but it worked well and was quick. I haven’t had any problems since.

Thanks keymaster. I still believe this isn’t the issue am having. Mine isn’t sound issue but tones are not playing out.

I still look for more comments on this.
Thanks.
Regards.
