Question about Onkyo Audio Players & Recorders
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

LM15 has an elliptical stylus so 1,5 - 1,8g should be sufficient, and also dial the same number on the anti skate for elliptical stylus and go for it

Balancing the tone arm is a two step process. Set the needle weight adjustment to zero(0) and make sure that the tone arm is balanced. It should rest horizontally without touching anything. Next, set the needle weight (usually 1.5 grams). Both adjustments should be on the rear of the tone arm. That should cause the tone arm to drop toward the record and have the correct pressure for the needle. Also, check the anti-skate adjustment. If that is off, the behavior you describe will occur as well.

SOURCE: Tone arm won't drop
This is a tough one. There is usually a series of gears that function in unison to make all the magic happens. These gears are usually set in motion by a smaller belt located inside the unit. If this belt has come off or is damaged, your unit will not work. Or, if the gears have cracked, or dried up, same issue.
Suggest taking it to a service center for repair.

Make a note of the tracking force setting.
Make sure the turntable is level.
Unplug the power to the turntable.
Using the tonearm elevation control, raise the tonearm.
Manually move the tonearm in toward the platter.
Manually rotate the platter ClockWise a few turns to disengage any cueing mechanisms.
Set the Stylus Pressure/Tracking setting to 0.
Disengage the tonearm elevation control. The tonearm will either float or drop. This is why we have no power, just in case it hits the platter.
Adjust the counterweight until the tonearm floats exactly horizontal. Use the flat portion of the tonarm rest as a gauge.
Return the tonearm to its rest.
Dial in the prescribed tracking force on the Stylus Pressure/Tracking control. Play records.
