New to forum, I have a 99 f350 lariat 4x4 powerstroke and i changed the batteries and the overhead "trip computer" now does not work i checked all the fuses associated with this and they are not blown does anyone have any suggestions.

 

Try disconnecting the battery once again. Maybe the thing didn't boot up properly.

Try turning the dimmer switch lol. It happened to me, I thought mine was broke.
