I had the same issue, but only after I pressed the reset button on the side of the panel. After a couple of days of troubleshooting, I found a small nick in the wiring from the outdoor unit to the indoor paneI. I turned off the breakers to the pool equipment, rerouted a new cat5 cable, but cat3 will work just as well, wired it up and all was good. A local pool guy wanted to charge me about $2000 to replace both units. I spent less than $5.

Good luck

I don't think so but go through your menu to see if the backlight is enabled. I have never heard of one burning out unless a surge or something fried the whole unit.

Testimonial: "To my surprise, it was not enabled, and that was the problem. I don't know how it got disabled, because it has been on for 7 years, but. . .Thanks!"
