I have a Pentair 400NT...... digital temp has been going out for a while. Then I went to turn on and I got the call for service error...... didn't mess with it for awhile..... had some time, so I figured I'd start troubleshooting again..... I have power to the board, but no LEDs..... I assume the board has finally totally died..... thoughts?
