Agilent 7200 Q-TOF-MS Mainboard Shutdown

Hello, all.

When I tried to execute autotune for our 7200 QTOF, I encountered a series of following faults.

Q-TOF fault detected: 5.31 Main board #1 shutdown

Q-TOF fault detected: 6.5 Lens 5 fault

Q-TOF fault detected: 7.30 Main board #2 internal shutdown

Q-TOF fault detected: 7.31 Main board #2 shutdown

The instrument was vented and powered back on, but the fault message continued.

Does anyone know how to repair it or what Lens 5 is?

I appreciate your help!
