Hello Folks,
I troubleshooting a portable R.O milleniun the old type which is working properly but the conductivity display is not. I cannot see what is the conductivity on the LED display. Any thought. Thanks

We had display boards go bad that we got from a 3rd party that has stopped making them. I'm guessing that you're out of luck.

Don't you think it would be the display circuit board, part number 12312? There is a conductivity circuit board 12311, but if the display is just blank, I would think the display board.
I am talking old, old here.

Chuck and Dave,
I already swapped the board for a good known , and still not displaying the conductivity . Also I swapped the the cable that connected the conductivity board to the internal board, and the internal board and still not displaying the conductivity. At this moment the only fix left I have is swapping the last board that holds the power transformer. Any more thoughts. Thanks

Do you have any way of checking to see if power is actually going to the display board or checking continuity?
