Did this happen after you upload a new code?
Can you post it?

nope, this happens after i calibrate ph. i jsut got back from the LFS where i purchase 7 and 10 solution.
i took the ph probe off the sump, rinse with ro/di and put in ph 7 soln.
went to controller, then set-up, then calibrate ph, ph in the controller then changes and then about 5-10 secs after, the display went blank. display has power, it is jsut blank, no numbers/ letters.
