There is a small control board attached under the directional pad. It sounds like it has come loose from the housing. You can get to it one of two ways. You can unscrew all of the back cover screws on the console and then pop the front overlay off using the tabs under the back cover or you can get your fingernails under the edge of the plastic on the front display and pop it off that way. Precor would not approve of doing it that way but it won't hurt the display. The small D-pad pca can be easily snapped back into place. If you get to the pca and its still secured in the D-pad, the control board itself may be bad.
