The LCD display/control panel on my Catalina spa went "dark" on me. One day it was illuminated and the next it wasn't. The heat and pump are still running and the buttons on the LCD still appear to control the tub - I tried using the buttons to turn on the jets and it worked (but, I was, of course "flying blind" since the panel wasn't displaying). Since the panel is still arguably controlling the functions it doesn't seem like it's a total loss (or even a fuse if one exists for the panel). Is it simply a bulb that lights the panel? Help, please?
Thanks,
Rick
