SOURCE: technic 1200 mk2 turntable wont spin
need to know if it powers up. Does it try to spin, do you hear it trying to spin? More than likely the on/off switch went bad. No, I am not referring to the ON/OFF knob. THere is a switch this engages when turned. The part is S601. You might also want to replace the Start/Stop switch as well. If neither work, then the issue is on the main PC board, and probably IC101, or IC201 with the problem. At this stage, you will have to have a service tech look at your unit.

Most common problem is the belt getting soft, especially if it has sat for a long time. It will get a weak spot where it sat on the drive pulley and every time the turntable goes around and hits that weak spot it will slow down a little making it sound like a warped album.
The belts are usually very easy to replace. Usually just lift off the turntable or there might be a small clip on the center pin, then it lifts off. Replacement belts can be ordered from several places, as shown in this search... http://www.google.com/search?&q=SL-B200+Technics+turntable+belt

If everything seems ok with the power , there is usally a small microswitch that sends power to the motor when the tone arm is moved to the start of the record.
The switch might be bad or the lever that actuates it (connected to the tone arm) might be sticking. You may have to take the bottom cover off or remove the platter to see it.
Also make sure the belt is looped over the motor shaft. If the motor runs but the belt still doesnt turn, belt might be bad.

It is not suggested that you remove the ground cable. Performing the mod for the ground by soldering a bridge on the circuit board doesn't really do anything either than remove that buzz/ground hum. You've essentially removed the wire that grounds the turntable cabinet to the earth. The buzz is gone, but now your turntable is no longer grounded properly.
I would suggest replacing the ground cable to it's original state, then attach the Monster cables.
If this does not work, then either there is an issue with the soldering to the board, or the board itself might be damaged. You might want to look at the trace paths to make sure none are lifted, or damaged in any way on the board. Another issue might be faulty tonearm wires or not properly soldered wires.
FYI, monster cables are not good for this purpose. I would suggest the following cables:

Yes you need a pre amp
It would also be the same if you connected it to a computer to record an LP to CD. Mine is a little different and has one already built in that I can switch in and out of line.
Try spend a little more if you can as many pre amps can introduce noise.
You may also want to check that the turntable is properly grounded to prevent noise too
