65,
What happened just before you found the problem? Were you doing anything inside the ET or reprogramming?
If ScreenLogic is working then the com port on the main EasyTouch board must be working. I would make sure ScreenLogic is working by doing something like turn on the pool light and make sure the the light comes on.
When the ET is talking with the pump, the pump's controls will not work and the display will say "Display Not Active"...
I would go into the Menu, Settings, IntelliFlo, Pump #1, and make sure the right pump model shows up.. In my case it says VS..
You can shut off the main breaker that powers your EasyTouch, wait 30 seconds and then power everything back up.. I doubt it will help , but worth a try..
After that I would think the com chip in the pump is bad.. We have seen pics of the connector where the cable plugs into the pump, where one of the pins had corroded away..
Thanks,
Jim R.
