Component-level repair
iPhone motherboard and logic board repair for faults a parts swap cannot explain.
When an iPhone has no power, will not charge, boot-loops or has liquid damage, the visible symptom is only the starting point. We inspect and test the board first, then explain the repair route before any work is approved.
The fixed £35 diagnostic charge covers microscope inspection, short-circuit tracing, fault isolation and both-way UK shipping. If you approve the final repair quote, the diagnostic fee is deducted from that quote.
Why board diagnosis matters
Parts replacement and board-level repair answer different questions.
A screen, battery or charging port replacement only helps if that part is the fault. Board-level work looks deeper: power rails, shorted components, corrosion, damaged pads and circuit paths that cannot be confirmed from the outside.
Microscope-led inspection
The board is inspected under magnification before repair work starts, so visible corrosion, damaged pads and previous repair marks are documented early.
Short-circuit tracing
Power rails are tested with bench equipment so shorted components and abnormal current draw can be isolated before parts are replaced.
Water damage recovery
Liquid-damaged boards are assessed for corrosion, damaged pads and unstable power behaviour before we decide whether repair is viable.
Charging & power faults
No power, boot-loop and charging symptoms are traced through the charging and power-delivery path instead of assuming the charging port is the answer.
What we repair
Fault-specific iPhone repair services.
Each fault family has its own dedicated page covering the symptom, the likely causes and what the diagnostic finds:
Track the job
Clear repair tracking from booking to return.
Status updates at the points customers usually ask about.
Tracking covers the customer-facing stages of the job: booking, shipping, lab arrival, diagnosis, quote decision, repair, testing and return dispatch. Updates are written in plain language.
Your quote, your decision
Approve, decline or take more time.
The diagnostic report explains the finding, the proposed repair route, the quote and any important risk notes. You choose what happens next:
Approve the quote and we continue with the repair route described in the report.
Decline and your device is returned by tracked shipping. No repair fee is charged; the diagnostic fee remains paid for the assessment, report and shipping already provided.
Extend the quote window for up to 28 days if you need more time to decide.
90-day warranty on the specific fault repaired.
Eligible repairs include a QR-code warranty route tied to the repair record. Cover runs for 90 days from confirmed return delivery. Tech2Fix supplies claim labels at no charge for the first 30 days; from day 31 to day 90, the current £9.99 postage charge is paid upfront.
Book a DiagnosticSecure device access when testing needs it
We do not ask for passcodes during booking. If a test genuinely needs device access later, access is requested through a secure route rather than plain text, email or SMS.
Common questions
iPhone logic board repair FAQ
Can a dead iPhone be repaired without replacing the whole phone?
It may be possible. A dead iPhone, no-power fault or no-charge issue can have a battery, charging, software or board-level cause. Tech2Fix diagnoses the fault first and only then quotes the appropriate repair route.
What faults does iPhone logic board repair cover?
Typical board-level faults include no power, boot-loop, charging faults, liquid damage, power-management failures, shorted rails and other component-level problems that cannot be solved by swapping basic parts.
Is the £35 diagnostic fee deducted from the final iPhone repair?
Yes. The £35 diagnostic fee is fully deducted from the approved repair quote if you choose to proceed after diagnosis.
