Strange level and drawbar behavior on NE6

[Funkademic]

I have an Electro 6D that I recently turned on after several months of not playing it. (It had been sitting undisturbed in a clean office). As soon as it powered on, I noticed that the screen was showing a very rapidly changing "Level" indicator, as though someone were twisting the master volume knob back and forth very rapidly. And the sound coming out of my headphones confirmed this. It was extremely choppy.

When I tried to adjust the drawbars, they also appeared to be changing on their own in a very fast and jittery way, and could not really be pulled out beyond 4 or 5. They would get "stuck" there on the screen.

The screen would also show the "FX Level 1" or "FX Level 2" or "Attack" parameters also changing rapidly, interspersed with the general "Level" changes.

I've updated to the latest firmware and I also did a full factory reset, with no change in behavior. I thought this might be a dirty master level pot but given that several parts of the board (master level, FX 1, FX2, Attack, and the drawbars) are registering change information, maybe it's something more serious. Any insight?

See attached for a video that shows some of this behavior. And thanks!

I've never seen that specific behavior before, but there have been many similar problems cured by opening up the unit and making sure all the ribbon cables are securely fastened.

I was afraid you might say that. Alright, I'll take a peep!
