I have a aqua rite chlorine generator. I wanted to check my salt level after I opened the pool this week. I turned the system off and then back on to recalibrate the system. When I turned it back on the digital readout started to blank out. I tried again reset the system. On the 3rd try all the lights came on for approx 10 sec, and then went out. I turned the system off and now the power light and the generating light stay on with the system off. Also the digital read out is still blank. Is my circuit board bad? I would order a new one but want to see if anyone else has had this problem before I spend $200
