What we repair on the motherboard

We repair the motherboard at component level — instead of replacing the whole device. Always diagnostics and a quote first.

No signal / Wi-Fi / Bluetooth
Repair of radio chips and antennas when the phone has no network or keeps losing connection.
Charging

We remove corrosion and repair traces and chips damaged by moisture.

Frequently asked questions — motherboard repair

How much does a motherboard repair cost?
The price is individual and depends on the damaged chip and the scope of work. We set it after free diagnostics — we only carry out the repair after you approve it.
Is a motherboard repair worth it?
Very often yes — repairing a single chip is cheaper than replacing the phone and lets you recover your data. If the repair isn't worth it, we will tell you honestly during diagnostics.
Will I get my data back from a phone that won't turn on?
Usually yes. After a board repair the device usually works again with the data intact. If needed, we also carry out separate data recovery.
How long does a motherboard repair take?
Usually 1–5 days, depending on the fault and chip availability. We give you the exact date after diagnostics.
Do you give a warranty on board repairs?
Yes — we give a warranty on the repair and the replaced chips. We confirm the details on collection.
Do you repair boards after failed repairs at another service?
Yes. We often get devices after failed repair attempts — we will assess the board condition and the options during free diagnostics.
