Most repair shops will replace a faulty phone or laptop motherboard entirely — an expensive fix, if a replacement board is even available. At Cybrix Electronics, we go further. Our technicians are trained in board-level repair and microsoldering, which means we can identify and fix the specific component that has failed rather than writing off the entire logic board. This approach can save hundreds of dollars on a device that other shops would declare uneconomical to fix.
Motherboard repairs encompass a wide range of faults. Short circuits caused by liquid damage, failed power management ICs, broken charging circuits, BGA chips (like GPUs and chipsets) with cold solder joints or failed bumps, and snapped or corroded connector pads all fall within what we handle. We use digital microscopes, hot air rework stations, and precision soldering equipment suited to the fine-pitch work that modern circuit boards demand — many components are smaller than a grain of sand.
We're transparent about what's fixable and what isn't. Board-level repair requires an honest assessment of the damage first. Some faults are straightforward single-component replacements; others require extensive rework with uncertain outcomes. We'll tell you the realistic probability of success and the cost before you commit to any repair work.
From everyday wear to complex hardware faults — here are the issues we deal with most often.
A device with zero power response — no charging light, no boot, nothing. Often a failed MOSFET, charging IC, or power rail component on the board.
Corrosion from water or liquid damage targeting specific components or traces on the PCB. We clean, assess, and replace corroded components as needed.
Artefacting, no display output, or driver crashes caused by a failed GPU or its supporting components. BGA rework can reseat chips with failed solder balls.
Torn charging port pads, ripped SIM card connector footprints, or damaged battery connector pads that prevent proper electrical connection.
Components damaged from extreme overheating — burned traces, failed capacitors near the CPU or charging circuits. We trace and repair heat-damaged areas.
A dead BIOS chip prevents any boot attempt. We reprogram or replace BIOS flash chips on laptops and desktop motherboards.
Device charges at the wrong rate, not at all, or shows incorrect battery percentage due to a faulty charge management IC rather than the battery itself.
No cellular signal, constant searching, or Wi-Fi that won't connect can stem from a failed baseband chip or Wi-Fi module — board-level diagnostics identify these.
We carry parts and have experience with the following models — and many more not listed here.
From booking to pickup — a straightforward, transparent process every time.
Describe the fault and device — we'll confirm if it's a board-level repair candidate and advise what to bring (charger, battery, etc.) to assist diagnosis.
The board is inspected under our digital microscope at up to 45x magnification. We map the fault to specific areas and test components with a multimeter and DC power supply.
We explain the fault, the proposed repair method, the success probability, and the cost. For complex BGA or multi-fault boards, we set realistic expectations clearly.
Components are replaced using precision hot air, infrared reflow or direct soldering — depending on the component type. All work is performed under magnification.
The board is tested for the repaired fault and all adjacent systems. Phones are tested for all hardware functions; laptops are stress-tested before reassembly.
Hundreds of satisfied customers trust Cybrix Electronics with their devices. Here\'s what makes us different.
Not just connector replacements — we handle component-level work on fine-pitch BGA chips, 0201 components, and multi-layer PCBs.
A board-level repair can cost a fraction of a full board replacement. We make board-level repair accessible and affordable.
We tell you success probability honestly before starting. Board repair has real-world limits and we won't take your money on a hopeless job.
Successfully completed board repairs carry our standard 90-day warranty on the work performed.
Book online in under 2 minutes. No fix, no fee — guaranteed.
Board-level diagnostic and assessment is free. Simple component replacements (single resistor, capacitor, or small IC) start from $89. Charging circuit repairs start from $120. BGA chip rework (GPU, chipset, baseband) is quoted individually based on the specific chip and board — typically ranging from $180–$450 depending on complexity. BIOS chip replacement starts from $99.
All pricing is confirmed after the free diagnostic assessment. We do not charge for assessment time on jobs we decline to take on, or on jobs where the diagnosis reveals damage beyond economic repair.
