Fixing dodgy channels in my Mackie VLZ-1642 Modular Synthesizers

Fixing dodgy channels in my Mackie VLZ-1642

Pretty much as soon as I bought my Mackie mixer a lot of the channels starting cutting in and out and then some stopped working at all.
It's def not a problem with any cables, I've ironed that out for sure.
Guessing it has something to do with dust in there.

So how do I go about fixing this myself? Do I need to open it up and use contact cleaner or something?

Cheers in advance,
Jonny

Contact Mackie. That might be one of the models where they used an IDC type ribbon cable for the busses.

If so, replacing it is the first thing I'd do.

Last I hear Mackie ribbons were up to Rev G. And we all hoped they finally got them right. There is also a problem with their switches and also the normaled inserts (1/4",back panel) Both the switches and the inserts could be sprayed out providing you use a solvent that doesn't melt the plastic!! A safe solvent is the lastest contact re-new & lube from Miller Stevens. But do try it out on a small area first. The pots will melt with many products including the earlier Miller Steven.Ribbon cables are checked by running signal thru a bad channel and moving the ribbons around with the back panel removed. Signal will pop back. You only have one shot at that because when the signal pops back it will stay until you really need it.
Ribbons come in sets...do change them all and watch that you orient them correctly.
