I haven't used my spa at night in probably 5 months and tonight I noticed the spa light only seems to be changing to around 2 colors while the pool lights are doing all the colors normally. They are Jandy lights connected to a Jandy PDA system. They are all wired together and used to work fine. I see the spa light flashing red at times but it never stays at that, just deep blue and lighter blue. Is there a way to resync these or is my spa light dead?
