If your device has an unclear, intermittent or complex fault, this diagnostic service identifies the likely cause and provides a repair recommendation before further work is authorised.
Repair options
This service covers inspection, functional testing and a repair recommendation. No additional repair is carried out until the findings and quote have been approved.
Common symptoms
- The cause of the fault is not yet confirmed
- More than one component may be involved
- The device has an intermittent or complex fault
- A repair quote is needed after testing
What is included
The device is inspected and tested to identify the likely cause of the fault. We explain the findings and provide a repair recommendation before any additional work is carried out. Diagnosis is an assessment service rather than a completed repair, so no repair warranty applies.
Confirming your model
This general diagnosis service is for a device where the exact fault is not yet confirmed. Include the device make and model when booking.
Repair process and turnaround
Turnaround is confirmed after we inspect the device and check the required component. The device is tested before and after the repair, and we contact you if inspection shows that a different component is responsible.

Frequently Asked Questions
What does the general diagnosis service include?
Our diagnosis service covers a full technical assessment of your device. We check hardware components, test key functions, and identify the root cause of the fault. At the end of the diagnosis we will give you a clear explanation of what is wrong and what the repair options are.
How long does the diagnosis take?
Most diagnoses are completed within the same day at our Liverpool Street workshop. If the fault is complex or requires further investigation, we will let you know before you leave the device with us.
Will my data be safe during the diagnosis?
Yes. The diagnosis process does not access, alter, or wipe your personal data. We inspect the hardware and run functional tests only.
What happens after the diagnosis?
We will explain the findings clearly and give you a repair quote. You then decide whether to proceed. If you agree to the repair, the diagnosis fee is applied toward the total cost. You are under no obligation to proceed.
Is there a charge if I decide not to proceed with the repair?
The diagnosis fee is payable regardless of whether you proceed with a repair. If you choose to proceed, the fee is applied toward the cost of the repair. If you decide not to repair the device, the fee still applies for the time spent assessing it.
