FIX or WORKAROUND
- Close MassLynx Software.

- Start the vacuum system. If that does not work, keep the Xevo TQD powered on and proceed to step 5.
- Measure the voltages on any of the 10 pins on the turbo controller to PCB cable (J37). Some should be 24 V depending on the state of the mass spec.
- If all of the pins measure zero volts, replace the turbo pump (if needed - with upgrade kit including new controller and cables).
