Just getting stranger by the day !!!!
Yesterday it was the Brain Board that decided to go faulty and today the DSP card woud only show the Green Led the entire time.
I tried about three times and during the process (when the desk was powered down) Iremoved the effects cards and was going to systematically pull all of the optivcal cables from the OPT-8 cards --- I gave up before removing them.
I did however have a thought, although I doubt if under normal circumstances it would cause a problem but maybe with the d8b it could be different !!!
From the picture below, you will see that the big power cable has its outer plastic cover removed where it enters the RACK Unit and the shield is therefore touching the matal chassis of the RACK unit.

Could this touching on the metal case be causing any form of trouble. I did try some months ago the feed the exposed section of the cable back into the RACK unit and then insulating it, but this was quite difficult to do --- well on this desk anyway !!!!!
Any advicevwill be greatly appreciated and I apologice for the picture quality as I had to use my mobile/cell phone to take the picture and it is an older phone with a poor camera.
I am really starting to feel that the problem is somehow related to the Power Distribution board (eiter at the board or inside the Rack unit with the power circuitary), the Back Pane and their ribbon cable connections to the DSP and possibly Brain Board, but why it works sometimes and not others I have no idea, If I get the time tomorrow I will remove all of the ribbon cables associated with those areas and give them anoither clean and then see what happens !!!!!
I hope the photo has uploaded as I really have no idea as to how to upload/paste a photo into thr forum !!!
