Soundcraft Series Two mute problem

Hi,

my Soundcraft Series Two has developed interesting problem on a 8 channels, pressing mute button on even input channel mutes the odd one as well. Then I can unmute the odd channel by pressing several time its respective mute button, but the even channel stays muted no matter what.

Sometimes the odd input will not mute completly but I get flickering and dimmed LED affecting audio signal.

This behaviour is not related to CPU/Mute automation, as I tried to disable the CPU, still same problem

I had look into schematics, but I can't find anything which would relate between odd-even pair of channels.

Any help and suggestions are welcomed. Thank you.

Problem solved, posting for the reference.

There is a 8way ribbon cable which run between midi mute PCB and faders PCB. When it gets disconnected, inputs will mute. On my console there was intermittent concetion to respective fader board, which cause above described symptons.

Reseating the connector cured it all.
