Probabally because either it was noisy or had stopped turning.
The symptoms I have seen like this has been Signal output from the LCD controller board.
All inverter problems I have seen have caused no backlight, as the LCD info and the backlight are completely separate the inverter must be working, otherwise no info at all on the screen.
The output of the inverter is around 800~1000VAC.
