I have a catalina monterey spa (~4 yrs old). Recently the 30AMP BUSS fuse blew. I replaced and it everything seemed fine. I have come to notice that the light on the control panel is out. The control panel is a CAT200. I believe it is a Balboa panel but I'm not sure.

Can anyone tell me if the panel illumination comes is a bulb (that could be burned out and replaceable) or if it comes from a backlit LCD screen?


Thanks...Al

I stuck with it and did more research - In case anyone else comes across this problem....

Bulb Replacement
Another panel problem may be burned out backlighting
bulbs.
These bulbs can easily be replaced.
• With the power off, gently pry up the topside control panel
with a screwdriver. Next, locate the gray bulb holes in the
back of the panel. Use a screwdriver to twist the bulb
approximately 1/4 turn to remove and replace the bulb.
(Needlenose pliers may also be useful.)



Now to find the replacement bulb :?
