GE dishwasher - dead

My GE GLD5750N10CS button controls will not function. Several of the LED lights stay on, but nothing happens when buttons are pushed. Initially, I replaced one of the solenoid switches and spring/plunger since I thought that failed. No change. Today I checked and cleaned all ribbons and plug connectors that I could find including the control panel circuit board with alcohol to remove any contaminant. No change. I did order 2 more spring plunger solenoid switches from APP today in case it was both switches involved with latching the door as a simple, cheap fix.

About a year ago our home warranty replaced - I believe the control panel circuit board when it did the same thing. However, I cannot find the receipt to verify that is what was replaced since I was not home at time of repair. May have been the outer control panel where the buttons are pushed. Regardless, it does not work now. Help!

I forgot to mention that I already turned the power on/off several times, including overnight. No change.
