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.

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.

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 :-

Pitch problems

You would need to calibrate them to each other. Not very difficult, but not that easy either.

I would suggest taking it to a service center, and ask them to calibrate the turntables to each other. It's a matter of adjusting VR302, which is located underneath the turntable platter. You'll also need a frequency counter or similar - which aren't cheap.

Dj decks-no sound

You didn't state if you purchased this used or new. If used, maybe the tonearm or the rca cables are bad. Or, if you set it up inccorectly.

Just to be sure...


Make sure you have the line selected properly on your receiver, and if you have a tape function, press the button in and out. Sometimes this will affect the sound. Now, check to see if your getting any signal to your mixer. Make sure the toggle switch on your mixer is set for PHONO and not LINE. Raise all volumes, including heapdhone, and see if you hear or see anything on the levels.

If all is good, but no signal going to mixer, then you might have a bad tonearm or RCA cables....

To check, disconnect the cartridge/headshell from your tonearm. Look inside the tonearm, and you'll see 4 gold plated prongs. Make sure they are all evenly protruding. Also make sure they are all a shiny. If you see any black substance on any of the prongs, they need to be cleaned. If any look like they are stuck, and not sticking out like the other ones, this would also cause an issue. This cannot be repaired. You can try to get the prong to come out, but if it does not work, you will have to replace the tonearm.

If everything with the tonearm looks good, then the issue might be the RCA cables. There is no easy way to check this, other than opening up the turntable. This is not easy, and I do not recommend.

Let me know how it turns out.

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.

I have only one side of the signal coming through from the deck

More than likely either your RCA cables need to be replaced, or the tonearm is damaged. Do you use Ortofon Concorde cartridges by any chance? If so, the tonearm could be faulty, or the connection from your cartridge to your tonearm might be loose. Just tighten the nut a little bit more.

If you use different cartridges, then the issue is probably your RCA cables and need to be replaced.

IN either case, professional assistance is highly recommended.

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.
