Driver info display goes blank when shifting
 

My info display has been going blank when I shift thru neutral. Also the PRND432 intermittently does not show anything below the gear I am in and in manual shift the 1-5 are intermittent also. If I use the manual shift it will soon kill the display also. Jiggling the rubber slide sometimes will fix that (?) but if the display has gone blank it will not come back without shutting off the car. The trans is functioning fine. Help? shift switch? F125 switch? connection?
Thanks - my first big post
