Reply to CDJ1000 MK1 wont turn on

So I was able to pick up a CDJ1000 MK1 for nothing because it wasn't working. The guy I got it off said that when he had a cd in it, it sounded like the cd was spinning faster and faster and then he turned it off and hasn't turned back on since. Ive opened it up and tried to figure out what was wrong with no success. Just wondering if anyone has any idea what it may be or how to fix it. Ive looked all over google and I can't find anything
