Digidesign Control 24 Scribble Strip Bank Dead - Help

[g9builder]

Hi,

I have a Control 24 (the original not the newer C24). The middle bank of 8 scribble strips and all associated buttons and pan pots etc on that board have gone dead. I am assuming this is down to a dodgy power connector to the board.(previously when this happened a tap on the front panel bought them back!) I have tried taking the bottom panel off and the rear panel off but cannot seem to locate these boards or connectors to them. Has anybody else repaired one of the se desk and can shed any light on how to carry out/check this repair. Do you have to remove the front panel to get to these boards? If so is there anything else to disconnect etc? Any help greatly appreciated. There is a mass of boards in there but these seem to be located behind other boards and I cannot get to them.

Thanks

Ian

I believe the Control 24 was the one known for bad power connectors.  If you search YouTube there is a video of how to take it apart and install a new harness.

Thanks - yes I have heard this also. Did have a check of the power supply but all seemed ok. I have read it is best to remove all of the Molex connectors and clean them. Reading on the Digidesign Forum there was someone else posted this problem a few years back but unfortunately the thread died before an answer was posted. I understand there is a particular connector on the power supply which feeds these 3  scribble strip banks. I don't understand though why only one bank  died when all 3 are daisy chained together from this one connector on the power supply. Surely if the power supply connector was faulty all three banks would go down? It appears though cleaning this connector should sort the problem out.  Other people complained of just 2no strips from a bank of 8 which went down and was sorted via cleaning of this power connector. Anybody care to explain that one to me?

Sorted.
Power supply was all ok. The actual harness that sits on the scribble strip was at fault. Literally just pulled it off and on a few times and all was back ok. Real P.I.T.A to get to though.
