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.
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.

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
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.
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.

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.
