This could be the result of pitch adjustments gone awry. Also, you may have both the 45 and 33 1/3 buttons pushed down which cause it run at 78. Here are a few trouble shooting tips and you can find the full manual for the TT at the link posted below:

Record sounds too fast or too slow. 1.) Turntable is set for wrong speed. Make proper speed selection for record type being played with platter speed buttons. 2.) Variable pitch is engaged. Depress quartz button or return pitch adjust slider to center detent position to engage quartz lock. Moving pitch adjust slider produces no effect. If the LED next to the pitch adjust slider center detent position remains green when the slider is moved, quartz lock is engaged. Depress the quartz button to disengage the quartz lock and activate variable pitch. The LED should turn RED

disconnect the wire at the compressor to check that the clutch is releasing,then with a test light check to see if power is present when it is switched on and no power when off.

Hi Ed, The 4 X 4 is selected after slowing to about 20 mph and is best deselected at standstill or very slow speeds. On occasions you may have to stop and reverse a short distance to get disengagement. The differential lock should be engaged in the same way as the 4 X 4. It should be used only if traction is lost and the vehicle loses traction with a wheel spinning free. Never use diff lock on hard top roads and always disengage as soon as possible. Regards John

Hi Jimmy. Does your machine display and flashing lights, if it does, count the flashes between the pauses. This is a fault code. If you let us know how many flashes, we can help you.
It might be a stuck motor brush. Undo the caps and see if either brush is stuck. A light file with a fine file might help. Careful tightening the brush caps as they can crack if done up to tight.
Good luck. Neil.

VTM4 LIGHT ON after gear was changed, but car drives smoothly and CHECK NENGINE light does not come on. Have diagnosed and was told nothing wrong with transmission. Please help

This is a manual center differential lock button for 4WD models.
When you push this button, it manually locks the front and rear axles. An amber C DIFF LOCK light should appear on the dash board when engaged.
Push it again and it will disengage. It may take a few seconds to disengage, and a beeping will be heard until the diff is unlocked.

The center differential lock is only meant to be used in emergency situations. Driving with it engaged at all times can damage your differential.

if the system locks up disengage the battery then engage to reboot

Tried turning the wheel a little to disengage the lock function?

The hold/lock switch must have been accidentally engaged - see p.12 of manual for location to disengage it
