I have a DX7 that used to work fine, but gives no sound after not being used for a year…
I have not been able to determine the cause
this is what I have tried:
The battery is fine it says 3.2 Volt
I thought perhaps the relay could be the issue.
So I desoldered it and made a shortcut like this:

however I still get no sound.
when I turn up the volume really high I do hear some sort of very faint tone, it gets higher when i play more notes.
it doesn’t matter wich notes I play. it has nothing to do with the actual sound though.
Can anyone help me determine the cause?
