problem with HSV2000 EVA 6000

[Sitcom S.p.A.]

Hi, can somebody help me?
During a normal routine check, we found that the Controller B was not operating, the display is switched off completely, so all the lights to the right of the LCD except the battery, and also all the various lights ports on the back of the device, fp1, fp2, mp1, mp2, db1p, db2p only spy intercontroller "was lit and green.
We have tried off and on again, but also during the startup has not shown signs of life on display, while the battery indicator lights, fans etc still change color to light until it became all green, but everything else is off, then returned in the previous state.
I am attaching the log file.
