Question about Technics SL-1210 Turntable
What are the proper grounding handling procedures to check any malfunction on the TT? specifically in the case of the on/off switch has to be replaced because it wont start? even if the ligths and everything else in properly working ...
If you have power to the unit, all you have to do is unplug it from it's power source. Wait a few minutes, to allow any circuits to drain, and you'll be good to go. No need to ground yourself, as if you were working on a PC. You won't even go near any PCB (printed circuit board) components, so no need to worry about static discharge.
If you have power, and it just wont spin, then more than likely it's the Start/Stop switch that has gone bad (Part #S601) - You can PURCHASE THE PART HERE. You will need to de-solder the old power switch and replace with the new. You will also need to take your turntable apart from the bottom in order to accomplish this. Disassembly instructions are located here. However, if you have no experience with electronics, I would suggest taking this to a local service tech for repairs.

Tips for a great answer:
Clear the DTCs.
Ensure that the scan tool data is within normal operating range. Refer to Scan Tool Data List .
Verify the customer's complaint.
Perform the Visual and Physical Check in this section.
Locate the correct symptom in the list at the end of this section. Follow the procedures in the appropriate diagnostic table. If the condition can not be duplicated, or is determined to be intermittent, refer to Intermittent Conditions .
Notice: Use the connector test adapter kit J 35616-A for any test that requires probing the following items:
The PCM harness connectors
The electrical center fuse/relay cavities
The component terminals
The component harness connector
Using this kit will prevent damage caused by the improper probing of connector terminals.
Several of the symptom procedures call for a careful inspection. This can lead to correcting a condition without further tests and can save valuable time. This inspection should include the following areas:
Inspect the PCM grounds for being clean, tight, and in their proper location. Refer to Master Electrical Component List and Power and Grounding Connector End Views in Wiring Systems.
Inspect the vacuum hoses for splits, kinks, and proper connections, as shown on Vehicle Emission Control Information label. Inspect thoroughly for any type of leak or restriction. Refer to Emission Hose Routing Diagram .
Inspect the air intake ducts for being collapsed, damaged areas, looseness, improper installation, or leaking, especially between the mass air flow (MAF) sensor and the throttle body.
Inspect for air leaks at throttle body mounting area, MAF sensor and intake manifold sealing surfaces.
Inspect the wiring harness for poor connections, pinches, cuts, or other damage.
Inspect for loose, damaged, or missing sensors/components.
Use the following tables when diagnosing a symptom complaint
Lack of Power, Sluggishness, or Sponginess
Hesitation, Sag, Stumble
Cuts Out, Misses
Poor Fuel Economy
Poor Fuel Fill Quality
Rough, Unstable, or Incorrect Idle and Stalling
Engine Cranks but Does Not Run
Malfunction Indicator Lamp (MIL) Inoperative
Malfunction Indicator Lamp (MIL) Always On
I would not think the cruse control , is the light on when it does it ?

each time the ignition is cycled, all 5 mode indicators light simultaneously, as an indicator check to ensure proper operation of the indicators. when the ignition is on, the transfer case shift control module illuminates the indicator lamp that corresponds to the current atc gear position, by providing a ground through a current limiting driver.
the transfer case shift control module flashes each indicator lamp after a shift has been requested and continues to flash until the transfer case shift control module completes the shift.
a solid state circuit, located inside the switch, supplies ignition voltage to the lamps. the solid state circuit also receives voltage when the headlamp switch is in the parklamp or headlamp position. when the solid state circuit receives voltage from the headlamp switch, the circuit reduces the voltage that is supplied to the indicator lamps, dimming the lamps when the headlamps are on.
the numbers below refer to the step numbers on the diagnostic table.
