Hello,

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

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.

I have also had this problem with the same model turntable. I opened mine up and the problem seems to have been that the grease on the arm lift and cueing lever was gumming up the linkage between the two. (I suspect that my turntable hadn't been used in some time.) I managed to free up the parts by manually working the the arm lift (pressing it down) several times. I'm not sure that I needed to open up the chasis for this fix but it did help me to see what was going on. Good luck with yours.

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.

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.

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 have to replace the needle.

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

well jus put all new fuses and wires on it then report back to me

have you got anti skate adjustment

If the mat lifts up to reveal a hole then you might get at the belt that way. I would have thought that the platter will lift up anyway. It might be held by a clip washer, around the spindle, from the top, sometimes hidden under a glued plastic piece. If you can't get in that way unscrew the base.

Get an external pre-amp. They range in price from 25-100 and more, depending on the capabilities. All over Ebay, and electronics sites. That will fix your problem. Hope this helps

is the wire loose on either end? sometimes the electrical plugs can cause noise due to resistance, so trying different outlets might help too

You need to run that black wire to ground, perhaps a screw on your electrical outlet. You also need a pre-amp with your turntable, I use the mcm 40-630 you can find it many places for sale.

Did you ground the turntable? Most of them have a ground wire located somewhere that connects to a screw on your electrical outlet. You could be getting hum from your pre-amp if it is a low quality one. Try unhooking the pre-amp, if that is the problem you won't hear the hum. If the turntable ground is the problem you won't hear music with no pre-amp but you will still hear the hum.
