No Sync Signal Jrc Radar -
The multicore cable between the radome/scanner and the display is the most frequent culprit. Damage from cable flexing, loose terminals at the strip, or corrosion in the 10-pin chassis plugs can interrupt signal flow.
If signals are missing at the scanner, the encoder or TX-RX board may need replacement. Maintenance Tips no sync signal jrc radar

Antenna rotates normally, but no sweep on screen or “NO SYNC”.
Unlike some consumer-grade radars that embed sync data in the power line, JRC commercial radars use dedicated coaxial or multi-core cables for sync. This makes them immune to power-line noise but vulnerable to connector corrosion and cable fatigue.
The most frequent culprit is a loose, corroded, or damaged connection in the multi-core cable connecting the display to the pedestal. Scanner Unit Power Loss:
