Is a Dead iPhone Always a Logic-Board Fault?
No. A failed battery, damaged charging port, defective display, software fault or liquid damage can produce the same black-screen symptom. Board-level work is justified only after testing traces the failure to circuitry on the original board. If the cause is still unknown, start with the model-specific diagnostic rather than purchasing an assumed component repair.
When Might Board-Level Diagnosis Be Needed?
These symptoms may justify board-level testing after simpler causes have been ruled out:
- No power after a known-good charging and battery path has been checked.
- Charging or USB communication faults after the external port path is tested.
- Repeated boot failure where a software restore is inappropriate or ineffective.
- No display even though a known-good screen path has been verified.
- Signal, Wi-Fi, audio or touch faults traced to board circuitry.
- Corrosion, impact damage or previous work affecting board components.
These symptoms do not identify a particular IC by themselves. Diagnosis establishes the failed area and whether repair is proportionate.
Choose the Outcome That Matters
Restore the iPhone
Start with logic-board assessment. The quote covers the repair needed to restore the agreed function.
Recover existing files
Use iPhone data recovery. The recovery goal, encryption boundary and result check are agreed before work.

If existing data is irreplaceable, say so before assessment. Do not authorise Restore, DFU restore or board replacement merely as a test because those actions may erase or sever access to the original encrypted data.
How Assessment and Pricing Work
- Choose the model. Select the exact iPhone so the correct diagnostic and repair options are used.
- Book the diagnostic. The displayed specialist diagnostic covers fault-finding and is credited if the approved repair proceeds.
- Receive the findings. celltech explains the failed area, board condition, viable outcome, exclusions and further price.
- Approve or decline. No additional chargeable board, chassis, parts or recovery work begins without approval.
- Repair and test. Only the approved work is completed. Warranty and return terms follow the selected repair and order.
If you decline the quoted repair, the completed diagnostic remains payable and the order-specific return-carriage terms apply.
Board Condition and Repair Limits
Component-level repair keeps the original board and repairs the failed circuit area where that is technically and economically viable. A cracked or broken board is declined. A bent board can be assessed, but damaged layers, pads or solder joints may make repair impossible. A required chassis replacement is quoted separately.
What Happens to the Data?
Many board repairs preserve the original storage and security hardware, but no repair can guarantee a particular file or complete dataset. Modern iPhone data is encrypted and normally requires the original security path and correct passcode. celltech does not bypass passcodes, Activation Lock or account security.
How the Mail-In Service Works
Book the selected diagnostic online and follow the private shipping instructions supplied for the completed order. Arrange suitable tracked inbound postage with compensation appropriate to the iPhone's value and retain proof of posting. The return method and cost follow the order-specific terms.
Do not send a device to the public office address. The private device destination is provided only in the completed-order instructions.
iPhone Logic-Board Repair Questions
How much does iPhone logic-board repair cost?
Choose the exact model to see the current £39.95 specialist diagnostic and from £149.95 board-repair amount. The diagnostic is credited if the approved repair proceeds. The final price depends on the diagnosed fault, board condition and any separately approved chassis or parts requirement.
Can a logic-board repair save my iPhone data?
It may preserve access when the original board can be repaired, but no data outcome is guaranteed. If the files matter more than the handset, choose data recovery before work begins so the recovery goal and encryption constraints are recorded.
Can celltech repair every iPhone logic-board fault?
No. Suitability depends on the model, failed circuit, board condition, previous work and available repair path. Cracked or broken boards are declined; other cases are confirmed after diagnosis.
How long does board repair take?
Timing is confirmed after diagnosis because it depends on the fault, parts, board condition, testing and carrier journeys. No universal turnaround is promised.
What warranty applies?
Any completed board repair uses the warranty stated for that selected repair and the published terms. A paid diagnostic or assessment alone is not a completed repair and does not carry a repair warranty.
What if I do not approve the repair?
The completed diagnostic remains payable. The device is returned under the order-specific carriage terms, and no unapproved repair work is performed.
