The first thing to try is to resolder all connections to the flyback transformer. Also see the shield next to the flyback for any black marks - if the flyback's case is cracked, you might get arching.
Another common failure is the power supply, that's located right behind the power switch (slides out once you remove the back cover).
I'm afraid I can't listen to the mp3 now, so I'm just working from experience. :-)
