As the stylus touches the record the turntable stops rotating

Hi, with the tone arm sitting on its mount rotate the platter manually approx. 12 times. That should reset all the auto functions. Cheers john.

Hi, most likely the diamond tip has broken off your stylus. Remove stylus from cartridge and inspect under magnification. Replace if tip is missing or damaged. Cheers John.

It's called a stylus. What red or white caps are we talking about? Some phono cartridges come with stylus guards that flip up out of the way for play or down to protect the stylus from damage while in storage or during tonearm balancing. The stylus needs to touch the record groove directly.

Hiya, check and be sure the turntable is plugged into correct inputs, "phono"

If thats OK, then probably is the stylus but could also be the cartridge itself. Check the wires on the back of cartridge make sure they are fixed properly. If all Ok, then start with a new stylus first.

Hope it helps

Since there are no tonearm adjustments the only solution in the manual that comes close is to make sure the turntable is level. The other possibility is the no-brainer of checking the stylus cover is NOT rotated down, preventing the stylus from contacting the record.

A quick and dirty test of tonearm balance being too light would be to unplug the power and manually move the tonearm over the platter. Gently lower it to see if it floats in the air or lightly but firmly contacts the platter. That won't tell you if it is tracking properly but it might indicate or eliminate tracking force as the culprit.

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.

Did you get a manual with the unit? Is it set up correctly?

When you initiate a start do you hear the motor startturning (somewhere underneath the platter)? It would be real quiet and vibration-free or it would not be very good for use on a turntable. Is the drive belt attached? See the picture in the link.

What do you mean by the STOP mechanism? What do you mean by ON position?

How many pops? How long?

Manual Motor STOP occurs when the tonearm is swung to the right onto its rest.

As with any turntable the following advice for this one will apply:

The tonearm setup is critical for proper tracking. Do it again with extreme care if mistracking is your problem.

I found one model online and a review with some sample of music. Quite interesting...

The author complained about some things that clearly mark him as a stranger to finer turntables. Complaining about having to assemble and position the 'rubber band', aka the drivebelt, and the tonearm counterweight shows that he underestimates the precision required for a mechanism to rotate at a constant precise speed while properly tracking the microscopic undulations of the groove without skipping into the air or gouging it to death.

Some basics when recording from a turntable...
1) Place the turntable as far from speakers as possible on a solid surface that you will not touch during the recording
2) Keep the volume low enough that airborne sounds don't cause mistracking of the stylus *
3) Avoid anything that will cause vibration or movement of the turntable. (Tip toe)
* If you have a subwoofer, turn it off.

Some advice after reading the article: don't try to save recording time by playing the discs at 45rpm. The best tracking of the disc and recording of the minute details in the grooves will be at the nativespeed of the recording. Digital manipulation later only gloms up the accuracy you probably want.

In general, the fewer the conversions steps in the analog domain, the better; and the fewer the bit rate conversions in the digital domain, the better.

most likely this is the switch that selects among cd/tape/radio/record player. it could be the preamp circuitry in the player as well. it would not be the cartridge UNLESS you cannot see a little rubber 'seat' up inside underneath the cartridge that pushes the stylus tip out and down towards the record just a bit. if this rubber 'yoke' (seat) is missing you will get no sound even when you touch the needle tip when the record player section is selected.

'Skating' is usually due to very low stylus pressure, which can be adjusted using a counterweight.

Is this the picture of the turntable ?

Isn't that a counterweight at the back-end of the arm ? Can't it be rotated ?

If the counter weight is fixed, check the pickup mounting. May be it needs to be adjusted a bit forward (to increasing the stylus pressure).
