Electronic Repairs Cornwall

Cornwall Electronic Repairs delivers expert diagnostic and repair services for a comprehensive range of domestic, commercial, specialist, and legacy electronics throughout the region.

We specialise in diagnosing the root causes of faults and, whenever feasible, repairing equipment directly at the PCB and component level instead of resorting to the automatic replacement of entire circuit boards or assemblies.

From everyday household electronics and robust power supplies to complex commercial control boards and hard-to-replace legacy equipment, we welcome a diverse array of electronic repair enquiries.

Electronic Repair Throughout Cornwall

Electronic devices can malfunction due to a wide variety of factors.

While certain faults are relatively straightforward to diagnose, others demand a rigorous examination of power supplies, signals, semiconductor components, and individual circuit sections.

Typical faults we can consider include:

  • Equipment that will not power on
  • Intermittent operation
  • Equipment shutting down unexpectedly
  • Power-supply faults
  • Display and video faults
  • Audio faults
  • Overheating
  • Short circuits
  • Control-board faults
  • Failed electronic components
  • Damaged connectors
  • PCB track or solder-joint problems
  • Unusual or intermittent electronic behaviour

Every repair is approached on an individual basis.

What Types of Electronic Equipment Do We Repair?

We accept a diverse selection of electronic equipment, including:

  • Televisions and display equipment
  • Audio and Hi-Fi equipment
  • Game consoles
  • Computers and associated electronics
  • Power supplies
  • Electronic control boards
  • Commercial electronic equipment
  • Test and measurement equipment
  • Specialist electronic systems
  • Legacy and obsolete equipment
  • Prototype and one-off electronics
  • Individual printed circuit boards

Please note that this list is not exhaustive.

If you have electronic equipment that is not listed, please contact us with the manufacturer, model number and a description of the fault.

PCB Diagnostics

Many electronic faults originate on a printed circuit board.

Instead of replacing an entire PCB without proper investigation, we perform targeted component-level diagnostics to pinpoint the exact point of failure whenever practical.

Diagnostic work may include:

  • Visual PCB inspection
  • Continuity and resistance testing
  • Power-rail measurements
  • Short-circuit investigation
  • Semiconductor testing
  • Oscilloscope waveform analysis
  • Signal tracing
  • Thermal fault investigation
  • Component testing
  • Examination of connectors and solder joints
  • PCB track and pad assessment

Where available, service manuals and circuit diagrams can further streamline the diagnostic process.

Component-Level Electronic Repair

Upon identifying a fault, individual electronic components can be thoroughly tested and replaced as needed.

Typical components encountered during repair include:

  • Resistors
  • Capacitors
  • Diodes
  • Rectifiers
  • Transistors
  • MOSFETs
  • IGBTs
  • Voltage regulators
  • Optocouplers
  • Relays
  • Transformers
  • Inductors
  • Connectors
  • Integrated circuits

Depending on the board’s construction and overall condition, repairs to PCB tracks, pads, and solder joints may also be feasible.

While component-level repair isn’t always feasible, it offers a practical solution when replacement assemblies are prohibitively expensive, obsolete, or difficult to source.

Repair Rather Than Replace

Many electronic devices are discarded because replacing the entire circuit board is assumed to be the only practical repair option.

Whenever technically and economically viable, we prioritise identifying the root cause of failure.

Repairing at component level can sometimes:

  • Extend the useful life of equipment
  • Reduce unnecessary electronic waste
  • Avoid replacement of otherwise serviceable equipment
  • Keep older or specialist systems operational
  • Reduce the cost of replacing expensive assemblies
  • Provide a repair option when replacement boards are unavailable

The ideal solution always depends on the specific equipment and the nature of the fault.

Domestic Electronic Repairs

We evaluate a diverse selection of household electronic devices.

This includes televisions, audio equipment, gaming consoles, computers, power supplies, and various other electronic devices.

We specialise in complex electronic diagnostics, focusing on intricate system faults rather than routine cosmetic or mechanical component swaps.

If you are unsure whether your equipment is suitable for repair, please contact us before sending it to us.

Commercial Electronic Repairs

Businesses across Cornwall also rely on our advanced electronic fault diagnosis services.

Because commercial equipment often remains in service for many years, replacing an entire machine or system due to a single failed electronic module can be a costly endeavor.

We can consider:

  • Electronic control boards
  • Power supplies
  • Commercial PCB assemblies
  • Interface electronics
  • Power-control circuits
  • Specialist modules
  • Test equipment
  • Legacy commercial systems
  • Other electronic equipment where component-level diagnosis may be useful

We assess each commercial repair enquiry individually.

Legacy & Obsolete Electronics

Aging electronic devices can continue to deliver significant value long after manufacturers have officially discontinued support.

Component-level repair can be particularly valuable where:

  • Replacement PCBs are no longer manufactured
  • Original components are obsolete
  • Manufacturer repair services have ended
  • The equipment is specialist or difficult to replace
  • Modern replacements would require wider system changes

When original components are unavailable, we can often use suitable modern alternatives.

We have a special focus on acquiring unusual, obsolete, and hard-to-replace electronic equipment.

Electronic Testing & Fault Diagnosis

We use advanced electronic test and measurement equipment throughout the diagnostic and repair process.

Depending upon the equipment and fault, testing may include:

  • Digital multimeter measurements
  • Oscilloscope waveform analysis
  • Differential voltage measurements
  • Component testing
  • Semiconductor analysis
  • ESR and capacitor testing
  • Power-supply testing
  • Signal tracing
  • Signal generation
  • Thermal analysis
  • Functional testing

The objective is to gather evidence and identify the root cause of the failure, rather than replacing components without a thorough diagnosis.

Equipment Assessment

Not every faulty item is suitable for repair.

Before starting major repairs, we can assess the equipment to establish:

  • The likely fault area
  • General condition
  • Extent of PCB damage
  • Availability of replacement components
  • Evidence of previous repair attempts
  • Practicality of component-level repair
  • Whether repair appears economically sensible

Our goal is to provide a transparent assessment rather than upsell unnecessary services.

Previously Repaired Equipment

We also accept equipment that other providers have previously inspected, serviced or attempted to repair.

Please tell us about any previous work, including:

  • Components that have been replaced
  • Modifications made
  • Previous diagnosis
  • Known PCB damage
  • Earlier repair attempts

Previous repairs do not automatically preclude a successful fix, though they can significantly complicate the diagnostic process.

Is Every Electronic Repair Possible?

Unfortunately not.

Repair may be impractical because of:

  • Severe PCB damage
  • Extensive corrosion or liquid damage
  • Unavailable proprietary components
  • Damaged programmed devices
  • Significant previous repair damage
  • Lack of essential technical information
  • Repair cost exceeding the value of the equipment

Prior to undertaking any significant repair work, we will provide a realistic and transparent assessment wherever possible.
