Remove the drive belt and see if the turntable spins, if it does the drive motor is faulty, if it doesn't then (if this is a new turntable) it's possibly got a locking device to hold the turn table steady during shipping.

If the ribbon is not present make sure you fashion one of your own so you don't contaminate the belt with oils from your skin.

Hi Norman

Normally the belt does not go through any special tensioners or anything of that nature,The belt should go directly from the spindle motor onto the inside of the platter. Hook the belt on the motor section and lay the belt open wide inside the turntable. Next, replace the platter and manouvre the belt onto the platterinside through the two large holes

Lift felt on platter and and lift the platter section off the unit by putting your thumb and forefinger through the two large holes and pull upwards.There should not be any special routing for the belt and should go directly onto the spindle motor to your platter. Place the belt around the inside rim of the platter while it is still off the unit. Now replace the platter and move the platter around until you see the spindle motor through one of the holes. Use some tweezers to manouvre the belt onto the spindle motor. On some units you will have to lay the belt out inside the unit, replace the platter and manouvre the belt onto the platter. Hope this helps

its simple the belt goes around the platter and the motor spindle, thats it!

BASIC INSTALLATION: Most belts are easily replaceable. It involves removing the turntable platter (usually metal and they usually just pull straight up off of the spindle). The belt is placed around the inner lip of the platter. Platter is replaced onto spindle and then, through one of the holes in the platter, reach your fingers in, grab the belt from the inner lip of the platter, and stretch the belt around the capstan or motor shaft. You are done. Some turntables are a little more involved, but most are simple. Check yours out. I was helped by a nice gentleman on the e-bay auction.

ahh! same thing happened to me during a move. quite frustrating, but a simple fix: remove the plate and look at the underside. here you'll see a ring around it, place the belt around that ring. there are 5 holes total, one small in the center, two larger ones to the side, and two rectangular ones on the edge. as you're putting the plate back onto the player, grab the belt through one of the rectangular holes and place that part of the belt around the cylindrical moving post to the upper left the same time as you put the plate back in place. it sounds confusing, but it's simple, i swear. let me know if i can clarify anything for you.
