The belt needs to be replaced since it is slipping.

there is a (v.r) for speed in side look for it and turn it a little

Different cartridges put out various levels based upon their technology - make sure you are using the proper input for their output. A line level input 1V P-P won't work on most phono cartridges and will require a preamp to boost it to the higher level.

Take off the rubber mat and see if the belt is off the aluminum platter the record sits on you should be able to see the rubber belt when the mat is removed. If it is not there or broke it will need replaced.

Hi, platter needs to be rotating when you change speeds. Cheers john. Styluscity

Hi, remove the platter and check that the belt has not come off. Cheers john. Styluscity

Hello,
You don't need the original ground wire for Technics SL-BD20D turntable,
any plain cable can be used for this purpose...
you should connect turntable to your pre amp,should be a "phone" input at the back...
here are some suggestions for grounding....
---------

Plug in a surge protector to the outlet, and then plug all the components into that surge protector

Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.

Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
connect the ground wire to a screw on the electrical outlet.

Too causes of this problem. One the stylus is worn out. Two not enough pressure to the stylus. At the end of the arm is a weight this should move up or down. If you can see numbers on it increase it slowly to the higher numbers, trying it as you go. The trick is to apply the correct weight to keep the stylus in the grooves and not here a rumbling sound from too much pressure.

u mean the recor speeds and slows down? if its an older turntable there is some play in the bpms thats why most people get direct drive. my sugguestion is to look it over and tinker w things but dont break it. im sure you can find a manual online

hi,
Just watch the following video to replace the belt in your turn table.
ok

Poor ground at the phono cartridge. Turn your receiver off and remove/reseat the cartridge and/or the tiny leads to it.

You definitely want to make sure that your new cartridge is properly aligned for your turntable. This web site can help:

If you don't feel that you are able to get it properly aligned by yourself, a local dealer should be able to help you with this for a small fee.

Hello,

The stylus you need depends on your cartridge brand. Wich one do you have? (It will appears printed on your current cartbridge).

The link for this model's manual is a dead-end at the Panasonic website. I lodged an email complaint.

If the tonearms balance and anti-skate are set properly it should track correctly.

When you lower the tonearm does it actuallu drop onto the platter or does it seem to hover? Look at the stylus to make sure a dustball hasn't clogged the tip.

The ground cable is usually a part of the audio cable. A red lead(right channel) and white lead(left channel) and a black lead. If there is no black lead, you can connect any wire to the metal portion of the turntable and the ground lead on your receiver. For more information, or should you have further question, please visit my website at audioserviceclinic.com. You may contact me through the website. Thank you.

Are you sure it's not the amp it's connected to that's not the problem? Magnetic cartridges have to be amplified by a pre-amp inside the main amp. It's sole purposes is to do just that, so the rest of the amp can work just fine. Most of these pre-amps are just a single IC and a few other parts. From what you describe the IC is perhaps getting hot, due to some internal fault, when a signal is applied to it. Break the signal and it cools down making it sound normal. There could be one in the turntable itself, but I doubt it.
If you are good with a soldering iron you will find the IC by tracing the wires back from the turntable imput socket on the amp. Conecting the turntable to another amp will confirm it either way.

Good day. It sounds to me like the belt is worn. Under the felt of the turning section, there should be two rather large holes. Insert your thumb and forefinger and pull the table off. You should also see where the existing belt is running. Insert new belt around the motor first and replace the table section. Now, through the two holes, manouver the belt onto the table section until it spins freely

you need a phono pre-amp or a mixer...
