Hps40 oscilloscope displays (LP oscillator failed)

Hello to all

Is that someone had this failure:

For the light I must draw the battery and reset and lp oscillator failed mesage appears.

Either the LP oscillator is defective or there is a mechanical problem which causes an interruption/bad contact around the oscillator.
