Hey guys,

In my original diagnosis, the membrane buttons on the left panel of my Chroma Polaris were non-responsive to touch, so I ordered and carefully installed Paul's replacement panels according to the instructions at rhodeschroma.com. This needed to be done, no question about it, but the left panel buttons still do not work. Disappointing! I suspect the PCB that controls this half may have a failed component, but due.to the scarcity of replacement boards, I will have to isolate and repair this issue. The mod/pitch levers are also not functioning, but that may be beside the point right now. Not sure?

Before I go through the whole board probing for voltages with a multimeter, does anybody know more about this issue? Maybe which components could be the likely culprit?

Regards,
Joshua
