Logic Board
Repair

Logic board repair is component-level repair of your phone's main circuit board (motherboard). Our micro-soldering technicians diagnose and replace individual faulty components — capacitors, resistors, IC chips — rather than replacing the entire board, saving you hundreds of pounds.

Common signs include: phone will not turn on at all, boot loop/restarting, no cellular service (IMEI unknown), no Wi-Fi or Bluetooth, no sound, touchscreen unresponsive, or phone died after a drop. A free diagnostic at FoneWorld will confirm the cause.

Logic board repair costs at FoneWorld UK start from £49 for simple component replacement and range up to £150+ for complex IC-level repairs. This is typically 40-60% cheaper than OEM full-board replacement, which often costs £300-£600. Free diagnostic included.

Yes, FoneWorld offers mail-in logic board repair service across the UK. Ship your device to any of our 16 locations and our micro-soldering specialists will diagnose, repair, and return it. This is ideal for complex repairs not offered at local high-street shops.

If your device is still under manufacturer warranty, we recommend using that first. However, for out-of-warranty devices (which most logic board issues affect), our repair provides a 1-year warranty on all parts and labour — often better coverage than the expired original warranty.
