Once you identify the failed component, here is your repair pathway:
| Component | Repair Option | Replacement Cost (Est.) | Technician Difficulty | | :--- | :--- | :--- | :--- | | Scanner Encoder | Clean optical disc; replace LED/photodiode | $1,200 - $2,800 | High (requires alignment) | | Slip Ring | Clean with contact cleaner; De-oxit | $600 - $1,500 (assembly) | Medium | | SigCon Cable | Cut back corroded end; re-terminate with new connector | $200 - $500 (cable per meter) | Low | | Sync Generator Board | Replace capacitors; reflow solder joints | $1,000 - $3,000 (new board) | Medium | | Display Processor | Firmware reflash (JRC Service Tool required) | $4,000+ | High (certified only) | no sync signal jrc radar
A critical note on cost: A "No Sync Signal" on an old JMA-2100 series might economically total the radar. However, on a current JMA-9100, it is always worth repairing. Troubleshooting the "No Sync Signal" Alarm on JRC
