Tonearm doesn't automatically return technics sl-d 202

SOURCE: Technics SL-1600MK2

Tonearm lift is probably a deteriorated belt. Google it, it's pretty common. The platter spinning might be due to a bad control board. You'll probably have to go to a repair shop to diagnose it.

on page 8 of the above service manual for your model it shows 4 electrical switches that tell the computer what 'state' the mechanism is in at any given time. Either one or more of the switches are intermittant or the mechanism has dried up grease that is slowing down the operation and basically gumming up the works. the old grease would have to be removed and replaced when it is causing binding. The switch just to the right of where is says "microswitch ksf-023" is an 'open air' type and so would be the most likely suspect. it simply needs to be cleaned with a super fine file designed only for cleaning switch contacts. THIS SERVICE SHOULD ONLY BE PERFORMED BY QUALIFIED PERSONNEL ONLY!!!!!

I have also had this problem with the same model turntable. I opened mine up and the problem seems to have been that the grease on the arm lift and cueing lever was gumming up the linkage between the two. (I suspect that my turntable hadn't been used in some time.) I managed to free up the parts by manually working the the arm lift (pressing it down) several times. I'm not sure that I needed to open up the chasis for this fix but it did help me to see what was going on. Good luck with yours.

SOURCE: tone arm comes out and touches record, then goes back to cradle

See what kind of arm position sensing elements are used in your turntable (micro switches, optics or possibly other) and check if they work correctly - sometimes a microswitch can be damaged or have oxydized internal contacts or a badly soldered / broken wire and it will not function properly, causing the unit to stop automatically, the same might happen if the sensor is of optical type and there is some dust or broken wires or if the emmiter or sensor is damaged. Also, it could be a problem with the part that activates the switch / optics, it might be displaced or damaged.

If all sensors / switches seem to work well, then check the section which has wires going to those sensors / switches, it's the next probable location of the fault (it might be an electronic controller so there could be damage to some components, broken wires, dirty connectors or bad solder contacts).

It could as well be something else in the mechanisms, wiring or electronics, i just suggested a few things that might cause the malfunction you described.

Hope you can get it fixed.

Hi, could just be platter not fitted hard down on spindle. I suggest you remove the platter and place it upon a dead flat surface to check to see that the platter is flat. If it is flat refit to turntable ensuring it is hard down on the spindle. If bent discard and replace with new platter.Platters can be ordered for all model 1200/1210 from [email protected]
