My Behringer BCF2000 control surface developed some faults recently. In particular, it appeared to be resetting constantly (as if I was turning power on and off).
With some trepidation, I opened the chassis and discovered that two 1000uF 16V electrolytic capacitors in the power supply had fallen victim to the capacitor plague. I replaced these with a couple of 1500uF 16V electrolytics that I had on hand, and everything was well again.
Just remember, the plague can affect the power supply of any electronic device!
