1) you got it off ebay you can file a complaint, IF the CDJ it was it was false adverstiment

2)pay to get it fixed.

3) sell a CDJ that "Won't blow your ears!" on ebay

nothing else you can do.

If you’re adventurous, and its not under warranty, open it up.
I bought a CDJ-800 on ebay, no warranty, and after a month the platter started to get “stuck”
I opened it up, and it turned out that one of the foam pads that sense when you are touching the platter was stuck. I dislodged it, and cut it so it didn’t operate any more, and now the CDJ works fine.
Although my problem was mechanical, and I was sure of it, I know nothing about electronics, so if that is the problem, unless you’re an electrician, maybe don’t follow my advice.

I unplugged it for a bit, now everything works. Weird, and VERY scary
