I hear an electric buzzing sound coming from UNDER THE PLATTER when switched on. This is NOT the ground/earth buzz, the audio output is fine - this sound comes from the unit itself. The buzz stops momentarily as i press start/stop or the 45/33 buttons, or switch the cue light on/off - the continuous buzz comes back immediately. Buzz is there if the platter is spinning or not. After about an hour of being on, the buzzing eventually stops. The deck works perfectly otherwise. Does anyone know what this may be? Sounds like a dodgy transformer or humming motor?

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. darren

Make sure there is nothing on the magnet part of the platter. Also, sometimes, the screws that hold down the plastic protective cover underneath the platter might not be seated all the way. Lastly, look at the bottom of the magnet, and make sure that it is in tact, and nothing is bent, broken, or cracked.

Other than that, try switching out the platters from your other turntable, and see if the problem persists. You need to rule out what it is not, before you can proceed with finding out what is the problem. So if the noise moves to the other turntable, you know the issue is with the platter. If the noise remains on the same turntable, then you can rule out the platter being the culprit, and can isolate the issue to the turntable. I've never heard of this, and I've fixed well over 3000 Technics 1200MK2/MK3/MK5 turntables in the past 10 years. I am also considered THE 1200s MASTER. So, I am not sure what could be causing this noise, other than some foreign matter. If your in the NY metro area, bring it on by, and I'll take a look at it, or give us a call, and I'll try and refer someone locally for you:

There seems to be 2 issues with this unit. Usually when the platter speeds up very quickly, one of the IC (integrated circuits) are faulty and needs to be replaced. However, I've never seen the 33/45 lights come on in addition. So, perhaps the issue started with faulty 33/45 switches, and it then caused a short to one of the IC's.

This will have to be professionally serviced, as it is not an easy fix. There are various circuits on the main board which control the drive, so it's a matter of diagnosing which is the culprit. The 33/45 switches will also need to be tested/replaced.

The Solution:
1. Firstly unplug the decks!!!
2. Remove the slipmatts and platter
3. Unscrew the circular plastic cover (Note: 5 screws holding it down)
4. Upon removing this circular plastic cover you will see a clear piece of plastic covering a circuit board, open it up. Now you will see a two fuses one clear and one stripey. 5. Remove the fuses (Gently poke it out with a pen/screwdriver or whatever) and examine it and see if either or both have infact blown.
6. Bring the suspect fuse/s to any electric/hardware/music type store (or search the net) and try to get a replacment but make sure its the same as the fuse you removed!!!. A T250 mA fuse(clear) an a T1A Fuse (stripey) are stated in the Technics user manual.
7. Now get the new fuse and gently snap it back in to the silver holders.
8. Replace the clear plastic circuit board cover.
9. Screw back the the circular plastic cover (Note: 5 screws holding it down)
10. Replace the Platter and slipmats
11. Turn them on and spin away

Been seeing a lot of problems like this on the newer decks. if the lights instead of moving smoothly are moving a bit, then stopping a little, then moving a bit more. or just wobbling a little bit usually has something to do with the motors... I have also just had to have mine replaced to was having the same problem.... expensive
