Subject: [yamahacs80] Aftertouch problem

From: Fernando Zarone <fernandozarone@...>
Date: 2011-03-31

Hello,
my CS-80 has the following defect:
the notes C# D D# and G G# A do not respond to AT, in all of the octaves. All the others do.
Thinking this to be a problem of TKC, I replaced all of the (socketed) ICs, resoldered all of the wires, but nothing.
The problem is shown in both CH I and II presets.

Could somebody help me, please? Does the AT of these two groups of adjacent keys correspond to specific component(s) / boards?

I did not check the TSBs. Could they be involved?

Every help is very welcome.

Ciao a tutti

Fernando
