Connectors, sockets and PCB interconnections are common points of electrical and mechanical stress. Cornwall Electronic Repairs can assess suitable electronic equipment for damaged connectors, fractured solder joints, broken PCB pads, contaminated contacts and intermittent connections. Careful inspection, continuity testing and signal tracing can establish whether a connection fault can be repaired without replacing an otherwise…
Moisture, contamination and corrosion can cause anything from intermittent operation to complete electronic failure. Cornwall Electronic Repairs can assess suitable affected PCBs, inspect damaged tracks, connectors and components, and use electrical testing to determine how far deterioration has spread. Where damage is sufficiently localised, component-level and PCB repair may provide a practical repair route.
Older electronic equipment can remain useful long after manufacturer support or replacement boards have disappeared. Cornwall Electronic Repairs can assess suitable legacy electronics using component-level fault diagnosis, circuit tracing and electronic testing. Power supplies, capacitors, semiconductors, relays, connectors and damaged PCB connections can all be investigated before deciding whether a practical repair remains technically and…
Relays, MOSFETs, triacs and transistor switching circuits are used throughout modern electronic equipment to control motors, heaters, power supplies and other loads. Cornwall Electronic Repairs can assess suitable control boards and modules for switching faults, including defective relays, driver circuitry, damaged PCB connections, power components and associated control electronics using systematic component-level diagnosis.
Electronic modules are used throughout commercial, industrial and specialist equipment, but complete replacement units can become expensive or obsolete. Cornwall Electronic Repairs can assess suitable modules using systematic PCB-level fault diagnosis.
Electronic test equipment can remain useful for many years, but ageing components, power supply faults and damaged controls can eventually cause problems. Cornwall Electronic Repairs can assess suitable instruments using systematic PCB-level fault diagnosis.
A game console that will not power on, display an image or operate reliably may have an electronic rather than software fault. Cornwall Electronic Repairs can assess suitable consoles using systematic PCB-level fault diagnosis.
Computer faults are not always caused by software or a failed hard drive. Cornwall Electronic Repairs can assess suitable computers and peripherals for power, motherboard, connector and other electronic faults using systematic PCB-level diagnosis.
Amplifiers can develop faults ranging from complete power failure and distorted audio to intermittent channels and protection-mode problems. Cornwall Electronic Repairs can assess suitable audio equipment using systematic component-level fault diagnosis.
A television or electronic display that has lost its picture, will not power up or repeatedly shuts down does not necessarily require complete board replacement. Cornwall Electronic Repairs can assess suitable TVs and displays using systematic PCB-level fault diagnosis.
Power supply faults are among the most common causes of electronic equipment failure. We assess and diagnose board-level power problems including failed capacitors, switching devices, rectifiers, regulators and damaged PCB components.
