Murphy's law has it that as soon as I've found a buyer with cash waiting for my Yamaha MG24/14FX than the right hand channel of the stereo bus seems to have gone kaput! I've got a computer tech background (from the days when we used to use multimeters and oscilloscopes to fix mainframes), so I've opened it up to see if there is anything obvious like a loose ribbon cable or connector but can't see anything untoward. All the input and master sections are made up of big surface mount boards, the input modules handle 8 channels each and the master section is just one big board that the inputs are ribbon cabled to and the FX piggy backs onto. Being surface mount stuff I guess that taking it to a tech for any repair is going to be more expensive than the desk is worth and the Presonus desk that the sale was going to contribute to will have to wait. I know it's a long shot but if there is anyone out there has any low down on yamaha internals and any 'known' faults I'd like to hear it.
