Turntable will not work

If it's belt driven, maybe it snapped. It's just rubber.

You might not have got the belt in the right position. Or you disturbed something when you put it on.

Is the motor on the turntable spinning - wiring misconnected?
If motor is running then th epower is not being transmitted to the platter by either a belt drive or a pulley drive.. The belt or pulley has to be replaced to restore the missing friction

I suggest you lift up the turntable matt and see if you can see a belt, which has either broke or come off. You might need a new belt!

Switch/trigger problem.

I've got the same problem. When you put therecord on, spin it from the centre, and it will release the mechanism inside,this is what I do, and it works fine. I think the problem is that there are twoplates under the turntable, and there was grease between them, after a few goesthe grease disappears, causing the problem.

After my THIRD Ion turntable had the arm-lowering problem...

I rotated the platter counterclockwise about 12 times and it worked...for now. I'll keep my fingers crossed and hope it wasn't a fluke.

:-)

Hi Daniel, its a bit of a long shot however try this. With the turntable powered of manually rotate the platter approx 12 times to reset the auto operation back to default. John styluscity.com

take the turntable arm by your hand and place it above the record,then use the up and down lever to lower arm on record!!
