HARDWARE REPAIR
We inspect faults, diagnose and repair audio equipment based on its condition. The cause, parts and repair scope are confirmed before work starts.
OPERATING IN COASTAL AND HIGHLAND CITIES
The salty air in Phu Quoc, Nha Trang, Cam Ranh and Da Nang, and the damp mist of Da Lat, destroy circuitry fast. Oxidised SMD component leads build up a conductive salt layer that shorts power supplies, while chassis rust, and speaker cones and their surrounds rot after a single tourist season.
An amplifier board failing or a digital mixer freezing on a packed night is an operational disaster. A wrong fix, or pushing equipment on through clipping, can burn out a whole row of expensive drivers.
The biggest worry for expat managers is ending up with an unqualified repairer who invents extra faults, fits parts of unknown origin, or cannot explain the cause of a failure professionally in English.
TONY LAB AUDIO’S ENGINEERING CAPABILITY
We treat the sound system as the heart of a venue’s operation. Every diagnosis and repair follows strict engineering discipline to restore the equipment’s original performance.
An oscilloscope to analyse signal waveforms, a thermal imaging camera to find leaking or overheating components, and a THD analyser to trace the real cause of the fault.
Hands-on work on high-density boards: restoring switch-mode power supplies (SMPS), replacing power semiconductors (MOSFET, IGBT), and handling digital signal processing (DSP) chips and converter ICs (DAC/ADC) for Allen & Heath, Powersoft, Pioneer DJ and Lab Gruppen.
We check the functions and the reported fault again after component replacement or circuit repair. The repair record states the results and any remaining limits.
Repaired equipment is load-tested to a plan and a duration agreed in advance. The engineer sets the Gain Structure, checks the protection circuits and records the operating limits at handover.

REAL OPERATING EVIDENCE
TECHNICAL QUESTIONS
Whether it can be repaired depends on the model, the service schematics, the parts and its actual condition. Tony Lab Audio diagnoses first and only then confirms what can be fixed and the replacement options.
The fault is recorded in the diagnostic file; the proposed repair, the expected parts, the limits and the cost are sent to you to approve before the repair. Anything new found while the unit is open needs your further approval.
Yes. Once the repair is complete and the unit has passed a Dummy Load Test, it carries a genuine Tony Lab Audio electronic warranty seal before it is handed back to the venue.
Hardware Repair only diagnoses and repairs faulty equipment. Protecting speakers from rain, humidity and salt air belongs to the separate Waterproofing & Marine Treatment service. If speakers need both, the repair scope and the Marine Treatment scope are assessed separately after inspection.
Tony Lab Audio logs the request and confirms the response time based on the location, the severity of the fault, the staff and the parts available; on-site support is only confirmed after that assessment.
OUR COMMITMENT TO YOU
Tony Lab Audio records the cause, the parts, the scope of the repair, the load-test method and the warranty terms before doing the work.
