Narrative:

It was our 4TH leg on our 4TH day. We received abnormal indications on our instruments before takeoff in ZZZ. We complied with our maintenance procedures which delayed us 1/2 hour. After takeoff at 1000 ft AGL we received the same problem and complied with our QRH procedures and contacted our maintenance. They determined best course of action was to return to ZZZ to switch to a different aircraft. We returned and landed in ZZZ with first officer's navigation. Pfd inoperative because of problem and QRH procedures to select captain's side as primary; rendering first officer's side inoperative. I am starting to feel tired and landing at minimums with his side inoperative makes the approach a bit more stressful than normal. We arrive at gate only to find out we will be keeping the same plane and maintenance fixes our plane quickly and signs us off to go back to original destination of ZZZ1. I ask first officer if he is ok; with flying back to ZZZ1 on our now 5TH. He is neutral; but with bloodshot eyes. 2 passenger do not want to stay on airplane and get off by themselves; some of the others are apprehensive to stay on. I then call my supervisors and say; 'the crew is fatigued.' the flight gets canceled 15 mins later.
