Question about Technics SL-1210 Turntable

More platter problems

Just last night my 2 year old 1210 tech table platter started doing something I've never experienced before with technics. Assume my turntable is on and in play mode .....when I manually stop my platter it freezes and won't spin on its own again. At that point I can press stop and play again and it won't budge.....I can tell the magnets are still on, but it doesn't initiate motion on its own. Now if I just give the platter a little works fine and maintains it's pitch speeds just fine.....just not good if you like to scratch, cause sometimes it freezes on the sample rather than initiating its playback regularly. Does anyone know of a simple solution or do I need to send this in for repair?

Re: more platter problems

There is no simple solution for this type of repair. One of the drive circuits has gone bad on your unit. This is a common problem, unfortunately, not a simple one. The hard part is finding out which circuit has gone bad. There are a total of 8 various components on the main board which control the drive sequence on the 1200s. Anyone of these, or a combination of a few, could have gone bad.

If you have access to a multimeter and know how to use it, you should be able to tech the issue rather quickly, and I would suggest obtaining the service manual for the exact specs of each circuit. If not, you will need to take it to a qualified service center for diagnosis.

If someone tells you it's your pitch control, it's not. The pitch control will not cause this type of problem. It's either one of the IC's, the resistors, or diodes.

Sudden pitch change.

There is a speed control IC inside this unit that could be defective or the speed detect sensors could be faulty. WIthout seeing the actual machine it is hard to tell. This one is a direct drive if memory serves me correctly, so you should not have this kind of drift. With the unit only a year old, I would not expect a motor problem either. Can you tell if the drift is toward higher speed or lower? Or does it vary?

Technics sl 1210 will not start up

did you ever open the turntable. It sounds like the on/off switch is bad. Remove the platter and screws with a phillips screw driver and just make sure the connections are in place. make sure you disconnect the power first. let me know what happens afterwards.

Platter or motor or what?

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

High-pitched, repetitive squeaking noise from under platter on 1210MK2

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:

Technic SL - 1210M5G problem.

I would suggest you verify you motor is sound, the platter is not rubbing. Is it direct drive or belt drive? You could go as far as check that your ac to your house is stable and the ac to dc rectifier/transformer/whatever it is called is good. When you say tables are never used or made within the last 6 months?

More details on the tables would help.

Technics 1210 mk2 problem with pitch and lights

Check that your voltage settings are set correctly. This is located underneath your turntable platter. If you remove the slipmat, you will see 2 holes on the metal platter. Rotate the platter till you see the voltage switch, located @ the 9'o'clock position. Make sure it's set to your correct settings (N.America = 115V / Euro = 220V). If not, you will need a flat head screw driver to switch it. Before you switch it, make sure your unit is off and unplugged. After you swich it, it should be ok.

If your still having issues with the speed and the pop-up light, then there is something seriously wrong, and will need to be checked by a technician. Sometimes a resistor or IC will go bad, causing the speed issue, but for the pop-up light - that's usually faulty wiring generally caused by an incorrect replacement.

Did you buy this new or used? Have you had this serviced recently?

Platter problem

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.

keep me poted.
