I took the two screws out from the bottom below the headshell spring-pin contact unit of the arm end. It's not comming off, I need to fix the contact which is stuck inside it's hole and won't come out. So I want to get the arm-end unit out, and I don't know if it has a "Trick" to it, or just lot's of force is needed. It's slightly loose, I can move it about 2 millimeters, that's all. Is there a screwing motion needed? Do I pull on the "collar" or on the end of the arm that connects to the head-shell? Please contact me at firstname.lastname@example.org .... Thanks.
There's no trick to it, it"s just pretty hard. I repaired this problem on a Vestax PDX2000. Besides being a super tight fit, it seems like they use some kind of glue at the factory. But if you can move the inner ferrule at all, you should be able to get it out. I used an un sharpened pencil to push it out but that was a straight tonearm. make sure someone who has some soldering skillz solders the wires back on. This whole process will take patience. You just have to ask yourself, "How bad do i want to save 75 bucks?"

Re: Arm head-shell spring contact unit removal
There is no trick to this. There is no easy way to repair that, unless you have the proper tools and experience. It sounds like your a novice, because of the questions you are asking.
Here is the issue you will come across...
You'll remove the collar, and find that there are 4 very thin wires soldered to the gold contacts. Those contacts have springs behind them. If they came off, or are damaged, that's it. Technics does not sell the parts for the tonearm individually. You will have to replace the entire tonearm. Soldering those thin wires back into their original position is extremely difficult. It's easier to replace the tonearm.

Check your rca plugs if the center pin is loose time to replace also you can check the lines using a voltage meter for continuity in the lines you can do that by putting one of the test leads on one end of the rca center pin (+)or outside ring (-) use the other test lead on the headshell or remove that and put the test lead into the end the arm. If both rca check out ++ -- then your cartridge may be bad. Remember the rca's are two line each red right white left with headshell off the lines should + to + - to -. hope this helps. Good luck.
You mean the 4 pins are stuck or have you solderd the wires first, too slow and know the plastic they fit in is melted . case one: use some grease(made for this purpose) and take pin by pin and ten they need to move after a couple of times and come back at theit start position by the spring in it, second case ... too bad and if you haven't done a thing then it's like 80% of the problems here, caused by lack of maintenance. Technics which have 20 year old capacitors which are never changed and still use the same rca cable and then they they wat 500 euro for such a unit:) funny guys.
sounds like your missing the cartridge......the cartridge screws to the head shell, & has 4 wires connected to it...blue / red / green / white. then the stylus,which is the needle, attaches to the cartridge. then the hole thing connects to the tone arm, with the head shell.
i recently bought one with the same issue. it has nothing to do with a turntable belt as the list of useless suggestions state below. you must remove the lid (when open, it should slide out by lifting directly upward), then you remove the rubber mat and metal plate. there you will see a plastic cover held on by 5 or 6 small screws...remove those and the cover. this cover exposes the opening that your tone arm will have to be above to remove the entire plastic shell that houses the entire inner workings. So, with the power ON...use the << button to move the tone arm over the opening (you may want to give a gentle push to the mechanism to guide it along). Once it's over the opening, you can begin to remove the entire cover. there are three screws on the top side of the unit (way down in three holes that were under the platter), then there are a number of screws on the bottom of the unit around the outter edge and one near the center. With those screws taken out, the cover should be able to be removed. Inside the unit, on the left (all the way to the back) is your small motor that spins a small black belt that turns the gears that pull the tiny steel cable attached to your tone arm assembly. On my turntable, this belt had sat so long that it had conformed into an oblong shape and wouldn't spin properly around the two wheels/pulleys. Make sure that you still have a belt there. If not, search the global interweb for one...$5-15 maybe?! I was able to remove my belt, cleaned it up a bit with soap and water (made it slightly pliable and tacky enough not to spin on the pulley/wheels), then put it back on AND........it works now. Hope this helps?!?!
Hi, Yes the "head" otherwise called the Headshell can be replace. They are a pretty standard fitting. You can remove it by unscrewing it from the arm. It should only take half a twist or so to release it, then lightly pull the headshell towards you.
Perhaps you have a broken wire in the headshell, or just a bad connection. Try removing the headshell to examine, if there's no break, try cleaning the contact pins that mate the headshell to arm connections.
See what type of cartridge is installed in the arm. Manufacturers use common cartridges in turntables, such as Stanton, Shure etc. Detach the head shell from the arm (it usually slips right off via a locking ring and four-pin mini plug) Look for the manufacturer and model number on the cartridge. No need to remove it from the head shell. On most modern cartridges, the stylus (as they are called, rather than the needle) simply slips off and on. No need to remove the entire cartridge (via screws) and re-align it. In fact, many DJs bring a set spare cartridges and styli on a gig, already mounted in head shells, and simply interchange them as needed.
When you have the make and model of the cartridge, go to Radio Shack or use their website to order a new one...or two. Or go to Google and enter "phono stylus" as your search term. You will find reasonably priced styli for nearly every cartridge imaginable. I operate 50 year-old turntables and am able to find replacement cartridges and styli on line. Ebay also has a number of listings, by make and model of the cartridge.
When the new stylus arrives, observe how easily the old one comes out of the cartridge- usually pull and slide - and slide the new one in. Re-insert the head shell on the arm, tighten the locking ring, and you're good to spin!
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.
