Bridgeport series1 Interact TNC151B problem

I tried to wire up my Interact today and it didn't quiet work the computer came on and once it got to the cross over__ axis screen it wouldn't start when I hit either the green button or the yellow one, and the yellow wouldn't light up. I did test the fuses and switches all are in working order. Also it wouldn't allow me to move from x axis selection every time i used the arrows it said invalid key entry.Pretty much the same thing that was happening to Maxvdh on his seriesII but when I hit the yellow button I cannot hear relays engaging or it lighting up. thoughts? -John
