Re: it wont turn on!!
If the fuse and the voltage are on the correct setting, the only other thing it could be is that the transformer fried, which is a common issue for Numark turntables. You will need to get it replaced professionally, as it is not an easy fix. Expect to spend anywhere from $70-100 parts and labor.

See if you can move the platter by hand. If it is very stiff then something will be stopping it moving. If you find the point at which the belt raps around the motor, again try turning it by hand. Put your fingers around the motor spindle. If you can't turn the spindle then the motor is knackered. If the motor turns easily, then it's likely to be a switch somewhere that turns on the motor. If this is the type of turntable that starts when the arm is moved away from the rest, suspect a micro switch connected to the arm is failing to make contact.
The only other thing I can suggest is to remove the underneath of the turntable to check the workings. You might also be able to see the bottom of the motor. If it is a 9 to 12 volt type, you can rig a 9 volt battery to it's terminals. The motor should then turn. If it doesn't then it's faulty.
Fuses blow when there's an overload. Mostly caused by a semi-conductor device that shorted out. If it's a transistor or diode it will be easy to spot with an Ohm meter as touching the terminals will be just like you have touched the two test probes together!
The step down adapter should work fine as long it supplies the voltage and any other ratings shown on the turntable power supply indication pannel. However the problem might already have happened. If the fuses were before the power entered the mains transformer of the unit, then if they were set to blow above the USA voltage then things could be OK. However if the the fuses were in the secondary output from the transformer then the mains will have caused possible damage to the transformer. Maybe even elsewhere.
Sounds to me like the capacitor across the motor needs replacing. On the + and - on a motor is a capacitor. This might be the problem, replace it as it should not be too expensive, you can never tell. Some times they are a few pence other time they are a few pounds. Why I don't know. If it's a common one, a few pence if it's a rare one, pounds....... I hope this helps.
Hi, the transformer that supplies power to the motor has been fried by the 220v input and will need to be replaced. If you remove it and go to your local electronic parts supplier they should be able to sell you a replacement. Cheers John styluscity.com
There may be a short somewhere inside that's causing it to draw too much power. If many other people are experiencing the same problem, then it may be a design flaw (like the original Xbox 360s).
As I always say, if it's under warranty/exchange, then just go that route by calling the manufacturer (for warranty) or just exchange it at the store you purchased it from.
If you're a gambling man, or find and understand the schematics, you could try stepping up the fuse to a slightly higher value. This isn't something you should seriously consider unless ALL other avenues have failed, as the fuse blows to protect the rest of the circuit from essentially melting down.
If everything seems ok with the power , there is usally a small microswitch that sends power to the motor when the tone arm is moved to the start of the record.
The switch might be bad or the lever that actuates it (connected to the tone arm) might be sticking. You may have to take the bottom cover off or remove the platter to see it.
Also make sure the belt is looped over the motor shaft. If the motor runs but the belt still doesnt turn, belt might be bad.
You have a short in your unit, and you will need professional assistance in determining the cause. You might also want to try a different outlet. If it fails, then you'll need to bring it to a service center for repair.
