clarification

what kind of laptop model you have?

This turntable has a preamp switch on it, which is probably on and what is causing the distortion. Take off the metal record platter by lifting up on the two holes gently. Turn the pre-amp switch to 'off' and then try it again. This is probably it...

Or you can plug it into an input that doesn't have a preamp and that should work.

most likely it's a 120vac motor. Get the bottom off and look for where power comes in somewhere on or around the base of the tonearm will be an actuator switch. unplugged, set the meter for ohms and operate the switch by moving the tone arm. You may have to use clip leads to get a free hand. The switch should read 0 ohms when the tonearm is moved. If not, you've got a bad switch.
While you are in there look around for anything that may have come loose or unplugged. Also, with it plugged in you should read somewhere between 110-120Volts ac between neutral and the motor side of the switch, when actuated. BE CAREFUL 110v can be lethal, or at the very least cause an unpleasant experience. Good luck

most turntables I've seen have male rca (phono) plugs on each end, but you have to get to the inside either by taking off the bottom or in some cases the body comes apart in two halves. If you get there and it turns out to be a solder on type (not likely) you can get the tails at radio shack. Most people with any audio equipment at all have an rca stereo pair lying around somewhere.

if you can solder, you can just put new rca ends on the existing cable . Good luck.

Remove the turntable pad (part where the record sits) and the switch is in the corner.

How does it sound when you just play straight vinyl through your system? If you still get that hum, issue might also be faulty RCA cables, and even cartridge. So you would need to test everything out.

You don't really need a pre-amp unless you are connecting straight into your pc from your turntable. In that case, yes you will need a pre-amp, and this actually might be the cause of everything. If you are going into a DJ Mixer or a receiver, and your turntable is connected to the PHONO INPUT connection, you do not need a phono pre-amp.

Here are some inexpensive PHONO PRE-AMPS.

Hope this helps some.

This is a BELT DRIVEn turntable. There will be variation as the belt gets worn, and they tend to have low threshold voltage regulators. So if your lights dim when say a dish washer, hair dryer or AC unit kicks on, you will see a noticable drop in speed/pitch on the record if there is a spike or surge in current.

Your old pioneer was probably DIRECT DRIVE, so the electromagnet can adjust itself, and is more stable.

try lubricating under the plater, on the spindle, and the motor, and check how worn the belt it.

If you have replaced the cartridge then it must be the cartridge pre-amp that is faulty. If there are any other functions on the device such as CD, then it will not effect them. Unless there is crackling on any other function then the pre-amp has a problem. The pre-amp itself is generally a single IC. You can find it by following the turntable connection back to the inside of the amp. The signals will pass through the IC before being passed to the main pre-amp.

Use an alternative device connected to the input the turntable usually connects to. If both channels work ok the new turntable is clearly faulty and should be returned under warranty.

You should go back to the local repair shop and ask them to do the job right or to give you the money back you presumably paid. You have a legal right to have them fixed properly.

Having looked at the turntable it seems to mount the cartridge with two bolt like fittings. The Cartridge you want has two mounts on the side that will take those bolts. You will have to adjust the arm to compensate for the weight differences between the two cartridges, but once done it should play fine.
