Fixing water damage, button failures, and communication errors between indoor and outdoor units.
Fault Diagnosis & Troubleshooting
Our systematic approach ensures accurate identification of complex intercom issues.
Power & Voltage Testing
Testing power supply outputs (24V DC/18V DC) and checking for voltage drops at the door station.
Audio/Video Signal Tracing
Verifying continuity of data lines to identify interference, cut cables, or impedance mismatches.
Door Lock Relay Checks
Testing the N/O and N/C contacts on the relay module to ensure the strike triggers correctly.
Cabling Inspection
Inspecting terminations for corrosion, loose strands, or short circuits in the 4-core/CAT twisted pairs.
Component Isolation
Systematically disconnecting peripheral monitors and sub-stations to pinpoint the exact faulty unit.
Component-Level Panasonic Repairs
We believe in a “Repair first — replace only if necessary” philosophy. Unlike many skills to repair individual components, saving you money and extending the life of your system. Our technicians are also experienced with Dahua, Aiphone, and Urmet intercoms, providing comprehensive security solutions for any property.
“Most ‘broken’ intercoms just need a simple component repair or a re-soldered connection, rather than an expensive full replacement.”
What We Repair:
Power supplies & transformers
Replacing failing capacitors, regulators, and fuses.
Audio boards & microphones
Fixing low volume, static, and feedback loops.
Speakers & handsets
Replacing blown speakers, cords, and hook switches.
Camera modules & screens
Restoring clear video feed and LCD brightness.
Internal connectors & boards
Micro-soldering broken traces and cleaning corrosion.
Audio Fault Repairs
Crystal clear communication is essential. We specialize in diagnosing and fixing high-frequency audio problems.
No Sound Both Ways
Complete audio failure often indicates a main board issue or severed cabling.
One-Way Communication
Microphone failure at either the door station or handset is a common culprit.
Distorted or Low Audio
Aging speakers or corroded connections can cause volume drops and distortion.
Buzzing or Interference
Electrical interference or grounding issues can introduce constant buzzing noise.
Video & Screen Repairs
Restoring crystal-clear visuals to ensure your security verification is never compromised.
Black or Flickering Screens
Often caused by failing capacitors in the monitor or loose termination points.
No Camera Feed
Blue screen or “No Signal” usually points to a camera module failure or cable break.
Poor Image Quality
Blurry, grainy, or washed-out video caused by lens degradation or interference.
Screen Power Issues
Monitor has power button light but display remains off? Internal board repair needed.
Door Release & Access Control Repairs
Ensure your property stays secure. We fix the critical link between your intercom and door locking mechanisms.
Electric Strike Faults
You hear a buzzing sound but the door remains locked, or the strike plate is physically jammed, preventing the latch from releasing securely.
We perform precision realignment of strike plates, replace worn-out solenoids, and verify consistent voltage delivery to ensure smooth operation.
Magnetic Lock Issues
The door can be shouted open due to weak holding force, or fails to lock entirely because of power supply voltage drops and misalignment.
Rectifying power supply units for stable current, realigning armature plates for maximum contact, and checking backup battery integrity.
Exit Button Failures
The ‘Press to Exit’ button feels sticky, unresponsive, or fails to trigger the door release sequence, trapping people inside.
We replace cheap plastic buttons with high-cycle industrial units and test both N/O & N/C switch contacts.
Intercom-to-Lock Wiring
Broken control wires, corrosion, or signal loss between the monitor, relay module, and the electric locking device.
Comprehensive cable tracing, repairing damaged termination points, or installing secure wireless bridges if re-cabling isn’t possible.
Why Melbourne Chooses Us for Panasonic Repairs
Panasonic intercoms are complex systems that require specialized knowledge. General electricians often guess; we investigate. Our dedicated team brings decades of specific Panasonic experience to your doorstep.
Specialized Diagnostics
We carry specialized testing equipment specifically for intercom impedance and signal tracing.
Genuine Panasonic Parts
We stock authentic replacement components, ensuring your system performs exactly as the manufacturer intended.
Workmanship Warranty
We stand by our workmanship with a comprehensive warranty. If the same fault returns, we fix it.
Panasonic Intercom Dead After a Blackout?
Did your intercom stop working immediately after a storm, power outage, or electrical work? This is likely surge damage. Often, only the internal fuse or power regulation circuit is affected, meaning the entire system DOES NOT need replacement.
Complete Power Loss
The most common sign. The monitor is blank and no LEDs are lit. Usually a blown thermal fuse saving the board.
Screen On, System Dead
Monitor powers up but shows “No Signal” or cannot communicate with the door station. Data lines may have surged.
Door Release Failure
You can hear and see the visitor, but the unlock button does nothing. The relay contact often fuses shut during surges.
Repairing Older Panasonic Intercom Systems
We disagree. Age alone doesn’t mean replacement. Whether it’s a legacy Panasonic or another brand like Hills Reliance or Bosch, we aim to restore your system.
Panasonic systems are built like tanks. Often, a simple refurbishment of the power unit or door station lens is all that’s needed to get another decade of life out of them.
We Still Service & Repair:
- ✔ Discontinued VL Series
- ✔ Analog Voice Intercoms
- ✔ Black/White CRT Monitors
- ✔ Hard-wired 4-Core Systems
Don’t Bin It, Fix It!
Full replacements can be expensive due to complex rewiring requirements. Our repairs typically cost a fraction of that.
Random Ringing at 3AM?
Few things are more annoying than a “Phantom Intercom” that rings when no one is there. This is a common but fixable fault.
Common Causes of False Ringing
Door Release Works — But Only Sometimes?
Intermittent locking issues are frustrating and a security risk. If you have to press the button five times to open the door, we can fix it.
Weather-Related Panasonic Intercom Failures
Melbourne’s “four seasons in one day” is tough on electronics. Extreme heat and sudden cold snaps cause specific expansion and contraction faults unique to our climate.
Summer Heat Failure
Symptom: The system works fine in the morning but stops responding or buzzes loudly when the afternoon sun hits the door station.
Winter Condensation
Symptom: Random phantom ringing or foggy camera lenses appearing after heavy rain or cold nights.
UV Lens Damage
Symptom: The visitor looks blurry or “milky” on the screen due to the plastic lens degrading under harsh Australian UV.

Common Panasonic Repair Myths
Don’t let misinformation cost you money. Here is the truth about repairing your Panasonic intercom system.
Panasonic End-of-Life Support & Advice
We believe in transparency. If your model is truly obsolete, we’ll tell you—and offer smart alternatives.
Compatible Replacement Units
When your exact model is discontinued, we source compatible Panasonic replacements that work with your existing wiring and monitors. This avoids costly re-cabling.
If your VL-SW250 door station fails, we can install a newer VL-V522 unit that connects to the same 2-wire cable without modifications.
Partial System Upgrades
You don’t need to replace everything. We can upgrade just the door station or add a wireless sub-monitor while keeping your main unit intact.
- ✓ Keep existing wiring
- ✓ Add modern features (HD camera, night vision)
- ✓ Significant savings vs. full replacement
When It’s Time to Upgrade
We’ll be honest if your system has reached true end-of-life. In these cases, we recommend a modern replacement with better features and longer support.
If repair isn’t cost-effective, we’ll explain why and provide a transparent quote for a new system—no pressure, just facts.
