Hi

I am having an issue that seems very similar to yours.

There is a diagnostics setting inside the M100, here:

http://www.retrosound.de/Matrix-1000%20Service.htm

THis lets you see which oscillator is not working properly.

Then I suggest you swap the CEM chips between the faulty one and one of the others....and if the diagnostics say that your problem is with the same oscillator as before, it is NOT the CEM chip but some logic circuit connected to it. The CEMs are easily swapped using a flat screwdriver pr similar, they are not soldered.

I did that, it was not was CEM chip, now I have turned the unit over to a repair guy to have it fixed :-/


regards
Håkon
