Lutron Grafik Eye Wall Stations Stopped Responding
The Lutron Grafik Eye system installed in our bedroom has stopped responding to input from the wall stations positioned either side of the bed; the master unit continues to operate normally.
The wall stations are still illuminated and changes on one are reflected on the other but have no effect on the master unit and hence on the light circuits.
The master unit is a 2-zone 3000 series; the wall stations are SO series. All units were installed 6 years ago when the house was built.
Are there any simple diagnostics we could run on the system to identify the issue or reset the circuits?

You can try to reset the grafik eye by turning off the circuit breaker to it for about 15 seconds and then turning it back on. Sometimes, they will get a surge and it freaks out the computer inside it a little bit. If that doesn't solve it, you may have a loose connection on the back of the grafik eye unit or one of the bedside keypads. There should be a 4 conductor wire (black, red, white, green) from the master unit to the bedside unit and then from bedside unit to bedside unit. The black wire is the common (ground), the red wire is the positive, and white and green are transmit and receive. It sounds like your transmit and receive loops are not complete (white and green). This would allow the led's on the front of the keypad to light up but not communicate to the grafik eye. Be sure to turn off the circuit breaker to the grafik eye before removing either the keypads and the grafik eye from the wall.
Good Luck
