I have a Jensen VM9311ts DVD Player and until

I have a Jensen VM9311ts DVD Player and until recently everything worked fine. A couple of days ago it had the smell of burning components and then the sound stopped. I figure its because of the internal amp but can not find out how to get the motherboard out exactly without breaking anything. I have circuit experience and am currently going to college for electronic engineering, so I am certain of myself. Just need help getting the board out.
