Camera won’t turn on

@ellianavannoort could be an issue with the DC circuit on your main board. There should be 2 fuses on it, one being the power fuse. It may have failed. Time to take it apart and to check things out.

Since iFixit does not yet have a guide for this, use something like this video (terrible music, turn the volume down ;-) it is for a A720 but should be similar enough to get you into your 710. Once you have it opened up and are at the circuit boards, take a couple of pictures of those boards. Post them with your question so that we can see what you see. We can most likely assist you further once we see what you have going on there.

While you work on your camera, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
