Kinda hard to tell from the vid, but it's probably the drive belt. If it's like the turntables I've seen, you should be able to lift the whole platter up and expose the drive shaft and belt.

i tried, i couldnt lift it. unless theres a switch or something.
i have this guy: https://s-media-cache-ak0.pinimg.co.....01dbd2ff22.jpg

Is that one of the all-in-one units?

it is indeed.

Cheaply made crap. Is it under warranty? Can you return it?

awwwhh but i love it. :'<
i dont think so. ive had it for a while. ;;

Well, you might try to have it repaired then. I still think the drive belt is the problem. Good luck! :3

I agree with Bannor that it's probably a belt issue.

As for lifting off the turntable, it can be done (fairly) easily. Around the spindle of your turntable is something called an E-clip similar to the one [that is pictured here]. Most likely it'll just look like a 3/4 round washer. They are quite resilient, so don't worry about the next step.

Take a small bladed screwdriver (the ones that look like a -, not a +), and using that picture above as a guide, try to wheedle in the screwdriver tip into one of the openings of the e-clamp and lever it away from the spindle. As mentioned, they are pretty resilient, so be aware it could spring off with a little energy.

With the e-clip free, the turntable should now lift off (you might have to coax it a little, though). From there, you should (hopefully) see if there's an issue with the belt.

What year is it? what make is it? and what model? Some Records have belts others it could be cylinder issues too if it's a more older expensive models.

Good luck repairing it! I definitely echo the probability that it's a belt problem; I had the same issue on my last turntable.

Hah, I have a similar one to that. The motor windings shorted out on mine so instead of 33/45/78 it does like 15/15/78. I don't think mine's belt driven. Kind of sounds like a gear broke and it's rattling it or something. To get the top piece out you have to flip the unit over and undo a few C-rings and then flip it over and lift the table out. Chances are it's fixable but not easily so unless you can find the right pieces online.

I got mine for $25 on eBay since it had "cosmetic" issues vs. the $100 retail they sell for. They're seriously cheaply made. The radio/control piece is a single integrated circuit.
