D,
Give us some more detail on the behavior you're seeing... you said:
"...but the display won’t stop blinking and I can’t select the option that I want to change (time,day,am-pm) because it jumps from one to the other non stop"
I'm assuming you did Menu > Schedules > picked a circuit (aux1, 2 or something), and now you're setting the time...
1. what item is flashing? (the "select" button cycles through the items you set, like mode, on/off hours/mins, days, etc)
2. what is it jumping from and to? it might be helpful to see what's on your display.
Just trying to figure out what you're actually seeing. It seems likes your board has a button that's stuck, but if the select button was stuck I think you'd have bigger issues.
