Question about Pioneer Audio Players & Recorders
SOURCE: Tone arm won't drop
This is a tough one. There is usually a series of gears that function in unison to make all the magic happens. These gears are usually set in motion by a smaller belt located inside the unit. If this belt has come off or is damaged, your unit will not work. Or, if the gears have cracked, or dried up, same issue.
Suggest taking it to a service center for repair.

The mechanics in your arm postion is throwing the switch. A mechanical postion switch has sliped out of postion, a arm from the toner arm post has moved to an encorrect postion, or if your turntable has a multi-album play abilty your 'next to play record' post postion sensor switch is out of postion. Last or first is your belt could fool ya. Your belt may have a weak spot on it in turn no friction underload.

K, I'm not familiar with that particular stereo unit but there were a lot of stereos from years gone past that used a turntable made by BSR. When you activate the switch to start the turntable listen closely to the record platter for a hum or possibly the sound of a motor turning (they're quite quiet). Is the switch lever you pull rectangular made of black plastic, you pull it towards you one click to start the record and pull it one step further (spring loaded) to make the tone arm lift from the record automatically? Just want to make sure I'm talking about the right turntable before we continue.

Are the record size tabs sticking up through the turntable platter cover? They sense the size of the record being played and adjust the run out distance for either 45 or 33 rpm records.

Most modern day turntables are semi-automatic. You move the tonearm from the rest post
over to the record and the platter will start turning. There is a small microswitch inside
either below the arm base or near. There should be a flat bar connected to the base of the arm
and this will actuate the microswitch. The switch is wired in series to the rotation motor.
Solution: 1. Obviously verify the belt is on. Take off the rubber mat and rotate the platter.
The rotation motor is on the left and it has a small brass spindle. The belt should
be visable through the holes in the platter. If not pull the platter gently up, there will
be some resistance. The belt wraps around a smaller inner ring on the underside
of the platter and the rotation motor spindle. If it is degraded it will be stuck to the
platter or fall apart. Generally there 3 common sizes. ( 21.4 / 23.6 / 25 inch) they
readily available on E-Bay, search term "turntable belt".
2. Obviously check power.
3. Check the microswitch, it should "click", verify with ohm meter.
4. Some turntables have a "cut" or stop function. The arm must return first to rest before
starting again, again the microswitch is the trigger.
