I posted this as part of my tone arm problem but haven't had any answers so I'll post it as it's own problem.
I have an SL-1200MKII and the platter is completely stuck. I've checked around, saw if you gave the middle knob a tab with a wooden hammer it can come free but this one is STUCK. It's been in storage for 5 years.
I put some WD-40 and let it sit to see if it would sink in but no luck. I've pulled very hard but am afraid of rigging something that might do serious damage.
Is there a way to get behind the platter? If I take it all apart, or is there a another suggestion someone might have?

Re: Sl-1200MK2 Platter STUCK
If you take off the platter does the motor spin? if not the motor isnt working. also make sure that the platter is able to freespin if not it may be unbalanced and the turntable needs to be opened up and leveled/raised. very simple its just a few screws on the motor in the center of the turntable.

Hi, have you tried manually moving the tonearm (with tt off) from its stating position across the platter to the centre? If you do this and find you get resistance at a certain point then there is damage to the tone arm base or bearings. Is the tonearm lifter going down completely?
The chances are the rubber drive belt has either broken or stretched so that it has fallen off the drive pulleys.
You will need to gain access to the underside of the turntable to replace it.
With most turntables the process will be to secure the tone arm (a rubber band will do the trick) before turning the whole thing upside down and unscrewing the base.
Replacement drive belts are easily available on the internet. Search by make and model number of your turntable
If you remove the rubber pad from the top of the platter then you should be able to lift the platter off the servo drives' center shaft,
from memory the unit is not attached just held on by gravity,if the servo magnet is gone the take it in for a service and pay the man for his time,
My first problem on my 1200s was a pitch control issue and easy to fix,with a little cash,never use second hand parts unless you know what you are doing because when they fail on you while playing to a packed dance floor then youll get more of a supprise than you barginned for,
If the force is towards the center of the disk, it's OK, it's the antiskating force. Set antiskating at 0, set the weight at 0gr, turn around the makeweight in order to set the tone arm parallel to the disk. With the antiskating at 0 the tone arm will stay parallel to the disk in the place you leave it. With the antiskating at any other position the tone arm will stay parallel to the disk going towards the center of the disk.
In case of a problem or clarification, don't hesitate to post.

(remedy) ok you can take the whole tone arm (remove the screw under the tunrtable , the rubber and the hard black and go to the tone arm position (under) there is 3 screw to loosen and then try to burn wher the screw position .i mean take some lighter.but be carefull...
the platter should have two holes on it,my 1210 does. put your thumb on the spindle and a finger in each hole and prize the platter off.
theres no screws holding the platter on just a tapered spindle shaft.
it is quite heavy so a good pull will do it.
as for the scraping it might be as simple as packaging placed under the platter to secure it for shipping, technics are built really well so i cant imagine it could be anything major.
i hope this helps you out, if you need any more help let us know.
please also let us know how you get on.
