Indoor Jandy AquaLinkRS keeps going blank,- circuit breaker off/on temporarily fixes

Jun 18, 2010

My Jandy AquaLink RS panel goes blank every few days, but a circuit breaker reset restores it for a few days. When the panel is blank, the pool seems to still run on program.
The part itself is almost $500 so I don't want to throw parts at it in "spray and pray" mode.
Are there any troubleshooting resources to figure out what I should check for to narrow down the possible culprit?
