I am going to be short and to the point.
Recently my NVR developed a fatal fault after a power outage where upon connecting any one of the PoE cameras the unit shuts down abruptly. The problem seems to be emanating from a faulty crystal (aka TF Oscillator / Tuning Fork Oscillator) which exploded (see similar pic for ease of reference).
Can anyone be gentile enough as to let me know the crystal value as it seems not printed on the component or on the PCB.
