Electronic Repairs & Component-Level Fault Diagnosis
Professional electronic repairs & component-level fault diagnosis services for home, commercial and specialist equipment throughout Cornwall.
At Cornwall Electronic Repairs, we investigate electronic faults properly before deciding how best to repair them. Wherever practical, we work at PCB and component level rather than automatically replacing complete circuit boards or assemblies.
Our aim is straightforward:
Repair rather than replace
We provide comprehensive fault diagnosis and repair services for a wide range of electronic devices, including household electronics, computers, commercial equipment, power supplies, control systems, and specialised or obsolete technologies.
What We Do
Fault diagnosis and repair of domestic, commercial and specialist electronic equipment.
We address issues including power loss, intermittent functionality, power supply failures, display and signal malfunctions, overheating, and various other electronic defects.
PCB Diagnostics
Comprehensive analysis of printed circuit boards utilising advanced electronic test and measurement instruments.
However, testing may involve measuring voltage and resistance, analysing power rails, tracing signals with an oscilloscope, testing semiconductors, examining components, and conducting thermal assessments.
Component-Level Repair
Whenever possible, we repair faults at the component level rather than replacing the entire PCB.
For example, typical component-level work involves replacing capacitors, resistors, diodes, rectifiers, transistors, MOSFETs, IGBTs, regulators, connectors, and other malfunctioning electronic components.
Repairs to PCB tracks, pads, and solder joints may also be feasible depending on the board’s condition.
Electronic Testing & Assessment
Not every defective item warrants automatic repair.
We evaluate electronic equipment to determine its condition, identify the probable cause of failure, and assess whether further diagnosis or repair is technically feasible and economically justified.
Legacy & Obsolete Electronics
Older electronic equipment can often continue to be valuable and functional for many years even after the manufacturer has ended support.
We specialise in diagnosing and repairing older, rare, or hard-to-replace electronic equipment, especially when replacement circuit boards or complete units are no longer easily accessible.
Commercial Electronic Repairs
We also specialise in electronic fault diagnostics for commercial equipment and circuit boards.
In some cases, component-level diagnosis is especially valuable when replacement assemblies are obsolete, unavailable, or excessively costly.
Examples of Equipment We May Be Able to Repair
Depending on the nature of the fault, availability of components, and cost-effectiveness, equipment selected for repair may include:
- Televisions and display equipment
- Audio and Hi-Fi equipment
- Game consoles
- Computers and associated electronics
- Power supplies and power-control electronics
- Electronic control boards
- Commercial electronic equipment
- Test and measurement equipment
- Legacy electronic equipment
- Specialist electronic assemblies
- Prototype and one-off electronic systems
If your equipment is not listed, please contact us to discuss whether we can help.
Uncommon electronic issues are always worth exploring together.

Component-Level Fault Finding
Our advanced component-level fault detection technology accurately identifies specific internal failures with unprecedented precision, significantly lowering costly repair expenses and successfully minimising disruptive equipment downtime.
PCB Diagnostics
Our advanced and comprehensive PCB diagnostics swiftly identify and meticulously resolve complex circuit board problems, ensuring a seamless process of restoring your critical systems to their peak optimal performance.
A Diagnostic Approach to Electronic Repairs
Successful electronic repairs begins with understanding why the equipment failed.
Our workshop employs advanced electronic test equipment and systematic fault diagnosis methods to accurately identify faulty circuits, components, or root causes of failure whenever possible.
This approach prevents unnecessary replacement of costly assemblies and enables repairs even when manufacturer replacement parts are no longer available.
How the Electronic Repairs Process Works
Here are the five key steps that outline our diagnostic and repair process, giving you a clear understanding of how we efficiently restore your electronic devices.
Step One: Tell Us About the Fault
Please provide the manufacturer, model number, and a detailed description of the equipment’s current function or any issues it is experiencing.
Photographs are especially valuable for documenting circuit boards and specialised equipment.
Step Two: Equipment Assessment
We thoroughly inspect and evaluate your equipment to determine the ideal diagnostic approach, then provide you with flexible return shipping options.
Step Three: Fault Diagnosis
We perform precise electronic measurements and essential testing to accurately isolate and identify faulty circuits, components, and assemblies.
Step Four: Repair Decision
After identifying the probable fault and repair requirements, we evaluate whether the fix is both technically feasible and economically viable.
Step Five: Repair & Testing
Upon approval of the equipment assessment report, we proceed with repairs on a time-and-materials basis, which includes thorough testing to ensure optimal performance to the fullest extent possible.
Have Something Unusual?
Not every electronic fault fits neatly into a defined category.
If you have a rare, obsolete, or hard-to-replace electronic device, PCB, or piece of equipment, please contact us with the details.
Therefore, we might still be able to assist even when traditional repair options are no longer accessible.
