Hi Eddos
where are you located ? in the EU or US,Canada ?
For your symthomes there are some possible reasons:
1. Broken 12V supply or GND Problem (this supply is not only for the 12V faders, it also Feeds the reference voltage for the AD converter (only one on the Brainboard) which converts the Vpot and fader signals to a digital value. If you do not have a stable 12V or the GND of the 12V is not connected to the GND of the 5V then you will have those effects.
2. rail cap Problem, yes that could be but I would not excpect it. But ist always good to replace them as a prevention task
3. 5V supply broken / unstable, This can cause resets of the circuits but I do not expect that this is your issue
I don't know your d8b, maybe you can open the CPU/PSU and send me some Pictures from the inside ?
best regards
Munk
