I haven't used our JVC AL-FQ5 turntable since we moved, but I put it away in perfect working condition and it was well-packed. Now, moved in, I can't find the instruction manual.
The problem is that although the tone arm lifts and moves into the start position, it won't drop onto the record. The piece that holds the tone up off the record does not descend so that the stylus can drop.
We thought of unscrewing the piece that holds the tone arm up and dropping the stylus onto the record manually, but, since it is automatic, when it gets to the end of the record it will no doubt return to the cradle--dragging the stylus all the way across the record as it does so.

Re: 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.

Does it restart if you manually lift the arm up?
If it does then you might have not put the belt on right. Another reason is that the problem was not the belt, but a motor showing the signs that it wasn't coping when under load. This could be caused by grease or muck inside the motor or in the drive functions. However the motor could be faulty.
Try, without any record on the table, if you can move the are, to the centre of the table. If you feel anything that is holding the arm, try to find out what it could be. Never use force. Also look inside if you can't find a clear obstruction on the top of the table. If you should find anything, don't bent, or don't break anything. Let a technical skilled person look why the obstruction is there and where the "thing" should be so the aren can move free. Perhaps you ned the obstruction for something only a few centimetres to the left or the right.
Even if the belt looks fine it's almost certainly the problem. You mentioned "cleaning" - if you got any kind of fluid on the belt it might act as a lubricant and reduce the friction between the belt and the drive wheel, causing the turntable to slow when the tone arm puts a drag on it. The problem may go away when the belt dries out.
The only thing that might cause something like that is a build up of static. You can buy anti-static products for records and turntables. I tend to use an anti-static spray which also cleans the records.
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.
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.
