My warranty has just expired and now suddenly my pitch adjustment is very stiff when I try to move it. I opened up the top of it and saw that there is some grease showing around the top as if it leaked. I opened up my other turntable and did not see any grease. Is there a way to fix that by taking it apart and removing the adjustment? Or will I have to send it in to get it repaired?

Re: Stiff Pitch Adjustment
What did you open up? The top of what? If you could be specific, I can direct you.
If your pitch is stiff, try spraying some contact cleaner or similar - DO NOT USE WD40. Use an electrical contact cleaning solution, such as CAIG DEOXIT or CAIG FADERLUBE both work very well, and are good for electronic contacts.
If this does not work, then maybe the pitch control knob/shaft is slightly bent? Any physical damage?
Other than that, there isn't a whole lot you can do, unless you replace the pitch control - Technics Pitch Control.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Register (free) at Vinyl Engine and download the service manual. The adjustment you need to do seems fairly simple. You will need a turntable strobe disk to get the the speed right, unless you have perfect pitch.
There's a variable resistor with the name pitch besides it... first clean it and then you put your pitch fader in the middle and turn it with a screw driver, put your platter on the unit, the plastic black plate you only have to unscrew and take off , nothing else., but like i said , but the platter on it and watch the strobe lights. Determine first which way you have to screw, it's just whole the time :taking of platter and turn screw a bit(don't forget to take of the electricity when you remove the platter), put it on and do that until the strobe stays steady.
It seems like you need to adjust the pitch control. Try looking at the platter strobe light and seeing if it is at the correct speed. If not adjust the pitch control until you can see the dots align. As for the not returning, your automatic motor may be busted.
You need to calibrate your pitch control. This requires a small precision screwdriver (similar to something you would repair eye glasses with). If you look under the turntable where the pitch control is you will find 2 small holes, 1 marked 33 and 1 marked 45. Turn the turntable on and set the pitch control lever to zero pitch. While the turntable is spinning insert the screw driver into the pitch calibration hole under the turntable and twist the potentiometer back and forth until the turntable pitch is zero (I believe clockwise is faster, counterclockwise is slower as you look up from the bottom of the turntable). This is a fine tune adjustment and will not require much turning to adjust the speed (1 or 2 mm's) either way should start to bring you into zero pitch. The platter speed can be verified by the little dots on the rim of the platter. They should appear stationary in strobe light on the power switch when you are at zero pitch. When you are adjusting the speed you will observe the dots on the platter rim spinning clockwise and then counterclockwise as you adjust the fine tuning. Fine tune the speed until the dots appear stationary and you will be back to zero pitch. You have to adjust the turntable at both speeds 33 and 45 using the correct fine tuning hole under the turntable. My personal experience is it is easiest to do this with 2 people. 1 person to hold the turntable level and running, while the other adjusts the fine tuning. Hope this helps.
sound like the pitch has been tampered with. Right you felling confer dent if so get your self a Philips screwdriver switch the deck off & unplug it under the slip mat there are two big holes put your fingers in them then twist & pull the platter off its always a mission because of the magnetic brakes. when you've got it off undo the 5 screws that hold the plastic cover on, then you'll see a circuit board on the top right hand side which has 2 pot one named BRAKE the other PITCH adjust the PITCH anticlockwise until it's slot is pointing up straight put it all back together but dont put the screws back in just yet. test it first if it's still not right repeat this proses untill you nail it. GOOD LUCK if you get stuk e-mail me firstname.lastname@example.org
THE PITCH slider or the variable resistor could have gone faulty. A new pitch is only $25 i think. They may need to salvage the pcb from your old one as technics no longer manufacters them. I've never seen the pitch led stay on lock when the actual pitch is not at zero. Hopefully the pitch did not short out the brake or the variable resistors on the motor's circuitboard.
Ok DJ,I use to Dj too,Probley you have moved the equipment quite a Few times,Is the Table Synchronous if so you might have some dust in you control throwing it off,Also Different locations have ac Voltage differences,Ck that too...
Other wise go to radio shack and pick up some Contact cleaner Good luck let me Know ttech
