Is it possible that they disconnected batteries to replace starter and when they reconnected , they forgot to reconnect one of the cables at the battery box? If not, then there should be a fuse for the display that may be blown. Did you check fuses or wiring leaving tripac going into sleeper? There may be an inline fuse blown to power up display. If it was working fine before they replaced the starter, then I suspect that a wire got missed when reconnecting all . Should double check starter area and battery box to be certain nothing was forgotten.
And the tripac was running fine just before the starter was replaced ? Correct?
Do you know what circuit the blown fuse powers .Is it for the tripac?
There is a main fuse under the tripac that is hard to spot but it may be blown as well -See if you can have a look for that . It may be a reset switch . I think that maybe they connected tripac the wrong way at batteries at first after starter was replaced and may have blown main fuse by accident. The main positive cable coming into tripac unit must go to a main fuse that may be blown . Itshould be in the lower portion of the tripac unit
If you follow the main positive(red ) cable , going into the tripac unit, it should connect to a main fuse or reset breaker.
There is also a reset button on the side of the unit in the sleeper.

Did you follow the main positive cable going into tripac ?
Follow it and see where it connects? Check for power there and check for corrosion or loose cables. I'm told there is a main fuse or reset underneath the unit. You may have to remove a panel to see it or access it.
