not ready state of MS TOF

Good evening. We have liquid chromatograph Agilent 1200 with time-of-flight mass spectrometric detector 6210 (Agilent Technologies, USA). After opening Data Acquisition Instrument Status of MS TOF is yellow for a long time and can't achieve ready state. The same for trying to do Tune. But when i want to start interactive sample it is green. I'll be glad to have some help with this question.
