  1. I replaced the board, same problem. It turned out to be a bad display.
  2. I have a Jandy Lite 2 heater that is arounf 15 years old. Never had a problem until this season. The display was missing an occaisional LCD pixel. Yesterday, it shut down and none of the buttons would work, I powered it off and on at the switch and now the panel fails to display anything. The control board power light is lit. I tried troubleshooting , there is power from the transformer but no power at the fireman switch when the 2 wires are connected but 24 volts on one leg when disconnected. I thought it was a bad display panel until I tested the voltage at the fireman switch. I don't want to buy a control panel if it 's a bad board.
