2007 suzuki vinson wont turn over
 

I have a 2007 suzuki vinson 500 4x4 semi-automatic. It is completely stock except for the tires. I went mudding last night and within 1 hour it backfired 3 or 4 times which it has never done. Then we went back to the mud bog but it wouldnt make it because the ice was so thick so I backed out of the bog and it backfired again. When I tried to restart it the display screen went blank there is nothing on it now. When I turn the key on the lights will come on and the display light will come on but none of the other stuff on the display does. I made sure it was in neutral and it was. When you press the start button you get nothing even when the keys on and I push my winch buttons nothing happens. I have not torn anything apart yet but I did put the air cleaner box and it was spotless no dirt no gas no water no anything. If you have any ideas please let me know what you think. Any help would be great since I have no idea where I need to start. I do not want to take it to the local shop. I was lazy for the first service and let them doit and did not get it back for 3 1/2 weeks. thanks
