I had a similar problem with both a Stage 3 and a Piano 4 at the same time. The flashing lights don't actually change the program, but it looks like all hell is breaking loose on the control panel. It's very disconcerting when the lights start flashing in the middle of a gig.

At the time I engaged Pablo (no longer an option unfortunately) but I never made progress as to the root cause. As it was across two very dissimilar keyboards, it was hard to blame the keyboard itself vs. something external.

I can't say exactly what fixed it, but I started with switching to better conditioned power and the problem disappeared. Not surprisingly, there's a lot of dodgy power out there. I also switched out a midi cable (spurious midi signals were a potential culprit) as well as floor pedals and audio cables.

One or more of these steps cured the problem, as I haven't seen it in over a year.

Thanks for the info! I'm mainly using it at home, but never had the problem before but somehow, it feels like a power fluctuation rather than button related. As per above though, I'll certainly look into using a good power source to test the potential problem.

Could be, if there is some AC flying around the board on top of DC that can cause a lot of problems; I would double check the power supply output and particularly the capacitors. Other possible cause is faulty buttons (Save and Program up/down)

I may have mixed up the kettle leads at some point, which may be affecting it. I'm going to look for the original. I'm not sure how to check the power supply output, do you mean within the keyboard itself?

Yes but if you are not skilled in checking and repairing electronics devices you should ask an expert/professional to do that for you
