I need to clean out the pitch sliders on my mk5g's ,,,do i do it the same way as i did on my 1210mk2 from under the base or can the slider be taken out through the easy access panel on the top ? also if i wanted to replace the pitch slider do i get a mk5 fader or is there another 1 for the G 's ??? thanks

Put the pitch slider to +6 and adjust the internal preset until the top set of dots on the platter are stationary.
Check again with the pitch at +3.3 if the dots are stationary then job done!, if not then the pitch slider is worn and perfect calibration won't be possible until the pitch slider is replaced.
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
usually, when you buy the pitch fader itself, then it comes with the circuit board. Ring up panasonic or a distributor and maybe they stock them, but im not sure why you need just a circuit board...and if u bought a pitch and it came without one, then just give a ring around...at least someone will stock it
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.
switch off for a will and see.
if still bad. check the circuit board under.
with old electronic devices, capacitors are commly the ones that may go wrong/dry. which would cause oscillatory circuit to generate wrong signals or strobe or feebacks. if you know how to take out the circuit board, check it starting from capacitors.
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 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.
You lack the proper tools to calibrate the pitch. Here are is a tutorial on calibrating your unit:
Also, that decal on the turntable that measures speed, is not an exact science. It's just an indicator to give you an estimate of the speed your turntable is rotating. It's not to be used as an exact measurement. Over time, pitch controls tend to drift from their original settings. Calibrating it back to factory specs might fix the problem, however, there are various other factors which control the drive of these turntables. So, if this does not work, the problem lies somewhere else - usually within 1 of the 3 IC's.
