Why tone arm stuck?

once you soldered to circuit board place - this might help Advanced Tonearm stuff Tightening the suspension on your tonearm Some TT's have tonearms which seem to be loose. If you grab the tonearm and pull it gently back and forth and it seems loose you can tighten it. It shouldn't move at all. A loose suspension can severely affect it's performance - from jumping needles to binding. It's pretty easy to tighten the suspension. You'll need a small flat screwdriver and a large one. Use the large one to loosen the outer locking screw on the top of the pivot point. Now use the smaller screwdriver to loosen up the smaller screw. Put a drop of oil where the bearings are (under that top support on the other end of the adjustment screw) so that it doesn't bind. Now tighten the small screw slowly until it just contacts the bearings. Adjust the tightness so the tonearm doesn't wiggle if you pull on it but leave it loose enough for the tonearm to pivot freely without binding. Adjust carefully and don't overtighten otherwise the bearings will be damaged! When done, tighten up the locking screw. Tightening up the headshell locking ring Have you put on your headshell, twisted that knurled tightener at the end of the tonearm as tight as possible and have found that the headshell still moves around? What will happen is that the headshell won't sit parallel to the record but may be tilted as a result of twisting of the headshell. This usually occurs when you change headshells a lot or if you've had your turntable for a while, and can contribute to needle jumping so here's what you do to fix it. First read 3.2 on base disassembly. Remove the rubber base. There will be this big piece of hard black plastic covering almost everything. You'll need to remove it. To remove the tonearm assembly look for three screws (all formerly under that black plastic) and unscrew them. Be careful not to drop the tonearm when you remove that last screw! Now, remove the tonearm assembly from the rest of the 1200, and look at the bottom of the tonearm where the headshell is put in. There will be two tiny philips screws there. Get a jewelers screwdriver of the CORRECT size and tighten those up. Put the headshell on and try wiggling it to make sure everything is right. Now put your tonearm back on and close everything back up. hope this helps peace DJ Nyce

You most likely have broken balls,,, lol yes balls bearings are most likely broke you might have to replace your arm.. about 80.00 for the part

It's very hard to get those screws aligned and tightened correctly. They are machine calibrated with the precise amount of torque. Once they become loose, it's very hard to get them back to original factory settings. Also, those screws are conical screws, which means they have a cone shaped tip on them. That cone shaped section sits on 4 very small ball bearings which balance the tonearm. There is a very thin piece of sheet metal which protects the ball bearings and keeps them aligned, if any of these parts are damaged, or bent in any way, your tonearm is damaged.

Unfortunately, if you can't get the balance correct, you will have to replace the tonearm. You can buy a new TONEARM HERE, however, replacing it, is a whole other process and not recommended if you have no soldering experience, as you could damage your unit even more.

Hope this helps.

sounds more like the grease is hard

(remedy) ok you can take the whole tone arm (remove the screw under the tunrtable , the rubber and the hard black and  go to the tone arm position (under) there is 3 screw to loosen and then try to burn wher the screw position .i mean take some lighter.but be carefull...
