My sisters pool has a Jandy Aqualink RS4 controller to operate the pump, booster pump, spa, etc. A while back it started reinitializing itself at random times. Now it just hangs during the boot process, usually with ALL the LED's lit and no display on the LCD display. Is there any hope for it? Does anyone repair these boards? Surely there would be good money in doing that. Jandy's prices are way beyond insane. Is there any low budget way to get it chatting with the power center again?
