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.
