Report "Just cleaned the unit. (Which I have done several times.) When pluging the unit back in I had the lcd display say the unit was in away mode. I pressed the buttons on the front to change the mode to 2500 sq ft, Hi-Fan. However when pressing the buttons the display just went white with no text. I then pulled it back apart to see what was wrong. The ionizer plate, (i.e.plastic sheet with screen epoxied to both sides), was out of it's groove on one side. I made sure it was seated correctly and put it back together. I had the same white LCD screen. It will not respond to the buttons. What do you think is wrong? Ben"
