I have had this unit since 2007, it has always worked perfect. I use it several hours daily.
Yesterday it stopped working. The key pads say NO CONTROL when I push any button with no backlight or any power coming on at all, it's just a scrolling message. The unit it self powers up but the 5 LEDs on the front blink and the LEDs under the cover are green, yellow, & red.
Pics below. Any ideas?
