does the cut white cable go back to the brown box - that looks like a VM cable that someone has cut - guessing it should go through the hole in the wall - thats certainly connected to a VM input
but theres another cable with a coax joint that could all be part of the original install - hard to know
you need a tech anyway to sort the spaghetti out and put a cover on the box so ring it in and see if you can get something booked or wait here for VM they will sort something
