I have a autopilot model DIG-220.Last year at the end of the season the digital screen would go off when ever you tryed to check any of the readings or shut the pump off. If i shut it off and turned it back on the screen would come back on. When I started the pool about 4 weeks ago it was working fine but with in the last few days it went out and won't come back on at all.I did check the wire harness inside they seem to be all pluugged in . Any help with this problem would be appreciated thanks, Bill
