Good Morning,

I have a problem my kn-6000 has lost the effects and some parts of rithms.

When I preform the test C#3-D#3-C#4 on page 3 (Other device test) I get the following message:

DSP IC304=NG
DSP PAM IC305=NG
IC306=NG

shouldn't it be "OK"?

How can I solve this?????

Many thanks for your help.

Jorge
