As there is a flat rate for the rent, it is not possible to ask someone to pay more. The fair way would be doing a semester switch like someone suggested or at least do a lucky draw. As for the TV, you may stay firm to keep it in your room. However, I would suggest to come up with a list of items that everybody want or need to use (e.g. vacuum, microwave, TV, etc) and then each person take the responsibility to contribute something. At the end, that item still belongs to the person who contributed it. If anything that is broken during your stay in that apartment, it should be replaced/fixed with even share. If you pool money to buy something now, it would be hard to decide who get what at the end. For the dorm room my D lived in last year, she provide the fridge and her roommate brought the microwave.
