1210 mk5g tone arm pin stuck

I bought two new 1210 mk5g turntable in March. Somehow on one turntable, one of the 4 pins inside the tonearm that connects to the cartridge is stuck in, the others seem to spring in and out but the one connector is stuck all the way inward.  Is their an easy fix or will I need to send it in?
They also do seem to play at a lower volume than my MK3's did.

Re: 1210 mk5g tone arm pin stuck

Hey raz, i've just taken apart and put back together my turn table trying to cure the same problem. I DIDN'T NEED TO!!!!
number 1) i think the tone arm is a sealed unit so far as i can gather so if the spring is broken you need a new tone arm. however. Get a cotton swab, soak in malt vinegar and use this to gently push the faulty contact in. The idea behind this is to get vinegar around the contact shaft. This should dislodge the dirt and release the contact.

Re: 1210 mk5g tone arm pin stuck

The inner connection spring is not making contact, so you're not getting full fidelity on both channels. Go here, these guys rule! Sounds like you'll need to replace the tonearm. And stay away from needle lickers.

I have recently removed the tone arm assembly and replaced the tonearm rest on my 1210's and now the tonearm is stiff horizontally so it stays in the same place and won't move across with the groove....

Check the arm wires have not got caught around the anti skate mechanism.
Did you adjust the screw / lock nut on top of the arm?. It's not supposed to be moved but if you did it might be to tight.

Short in tone arm

Unusual fault - I've never had a short inside the tonearm in all the years I've repairing decks.
A more likley problem would be a short (or an open circuit) in the phono cable.

Cable's and arms are available here :-

Tonearm not emitting signal into Serato

there is a switch that cuts off the signal when the tone arm docks.check the wiring is not broken inside and that the switch is ok.typically,red green white black red and white are plus and left ground is green and right ground is black.the collar that screws on to the head unit has 4 pins.make sure the contacts are clean.measure the wires one at a time from the tone arm to the rca plugs on the back.the green and black go to the outside collars,and the red and white go to the center pin of the rca plugs

Difficulty balancing the tone arm on kd-1033 turntable.

A new stylus should not change the tone arm balance setting if it is the correct stylus.

Does your arm have a sliding balance weight at the rear of the arm? If so you can slide this slightly towards the cartridge to regain the correct playing weight.

I would suggest you get a repair shop to do this for you, or you could finish up damaging your records.

Uh, hold the black headshell with one hand. With the other, twist the bumpy ringlock on the tonearm gently clockwise. Slide the cartridge out. You should be facing the TT.

Intermitant channel down

Hey, I'm having the same problem. I found this with a little help from a small site I found called Google:

Here's what he suggests. I have no clue what it means but I'm sure that it cane be decoded with some manuals:

Technics SL1210 , 1979 ?
Intermittent loss of one channel.
The headshell was slightly loose on the tonearm
and moving inwards would cause loss of one channel.
To remove this arm undo the slotted lock ring at the very top
of the arm pivot and undo the central pin. The arm
with jiggling can then be removed assuming enough slack in
the signal wires. Undoing the 2 watchmakers screws near
the headshell allows removal of the 4 pin connector.
Presumably the wires inside the tone arm at this connector
could touch the inside of the tonearm and lead to
break in sprung connection. Placed a bit of brass shim
in the slack area and pushed back in to wedge tight.
Also removed the soft washer on the plug shaft of the headshell.

Technics Sl-1210 MK2 GOES MONO

Check to make sure you have a nice solid connection on your tonearm from your cartridge. The problem is either your tonearm or your RCA (red/white) cables.

Neither are easy repairs, unless you have soldering skills/experience. The tonearm replacement is the more difficult and more costly of the two.

Parts for the unit can be purchased HERE. If you have any questions about testing your unit on the exact cause, please feel free to give our TECHS a call - they are available 24/7 for your convenience @ 1.866.668.1596 ext 1

Sound problem

first thing to do is take the left and put in in the right, do you get sound on the right?
now take the phono cartridge wires and move the left to the right and right to the left does the sound move or stay same place. if they move with or not tells you if the cartridge is bad or phono plugs. if they dont move it's the phono plugs if the does move it's the cart.
