I own a numark tt100 dj turntable i have a issue with the pitch my pitch slider is in the middle where it should be but the dots on the platter dont line up with the light
First things first, I presume you know that there's four pitch rings around the edge of the platter; one per RPM. So only one should be static when viewed by the synchronised light.
Second, there is a pitch fine tune control on top of the strobe light. Is that centralised? Presuming that you've checked the basics first, then it's time to look at maintenance issues, then faults/repairs.
If you're lucky then it could be something as simple as the motor spindle needing a couple of drops of oil. If the deck is from a very dusty environment then it may even need the motor spindle cleaning of accumulated dust and crud.
Anything beyond this is drag due to a bent spindle.
