The main circuit board within the scanner, which produces the sync signal, may have failed.
Always turn off the main power and secure the antenna before working on the scanner unit. Radar units emit high-frequency radiation and operate on high-voltage power.
The "Sync" or "AZI" (Azimuth) signals travel through the multi-core installation cable. Corrosion or loose pins at the junction box or the scanner unit's terminal board often cause signal loss.
Seek professional help if:
Typically 2048 pulses per revolution, telling the display where the antenna is pointing.
Switch the unit to and verify if the antenna rotates.
If the antenna array is not physically spinning, the encoder cannot generate the necessary azimuth or sync timing chains. no sync signal jrc radar

The sync circuit is closely linked with the rotation assembly.
