How this repair differs by device

Select a device group or read each section to understand the checks, part route and repair limitations.

Phone board repair

No power, charging faults, liquid exposure and damaged connector pads.

Board-level assessment can identify short circuits, corrosion, broken connections or power faults that standard part replacement will not solve. If data is the priority, tell us before work begins because the repair route may be different.

Laptop motherboard repair

Power-input, charging, short-circuit and damaged-connector faults.

We inspect the charger input and power rails, compare board repair with replacement cost and explain when a repair is not economical. A faulty charger or DC jack is ruled out before deeper board work.

MacBook logic-board repair

Startup, USB-C charging, liquid damage and unstable power faults.

The exact MacBook board and history guide the diagnostic route. Corrosion and previous repair attempts can change viability, so a quote follows inspection rather than a blanket success promise.

Tablet board repair

Charging pads, power circuits and liquid-damage faults on selected tablets.

Board repair is considered where the device value, damage and parts availability make it practical. We explain whether connector work, board repair or replacement is the more sensible option.

Repair scenario

A device still has no power with a known-good supply

The device does not start after its normal charger and cable have been ruled out. Inspect and diagnose the power path before replacing the board. Clarify whether a repair for daily use or access to data is the primary objective.

Illustrative repair scenario, not a recorded TECHHELP customer job. The actual fault and repair options require assessment.

Trust & clarity

Before you approve the repair

This repair is handled with a clear diagnosis route, quote approval, warranty explanation and realistic advice before paid work goes ahead.

Warranty and diagnostic note Warranty depends on repair type, part used and device condition. Liquid damage, impact damage, previous repairs and board-level faults may have limited warranty depending on the issue. TECHHELP explains this before repair approval.

Diagnosis before approval

We check the exact symptoms and device condition before recommending parts, board work or deeper inspection.

Parts quality explained

We explain the available part quality, repair testing and warranty before you approve the work.

Liquid damage needs inspection

Liquid damage warranty is limited because corrosion can continue after cleaning. We focus on realistic advice and safe recovery options.

Board repairs are diagnostic-led

No-power, short-circuit and logic-board issues are quoted after measurement, not guessed from the symptom alone.

FAQs

Repair questions and answers

Practical answers for the devices and faults covered on this page.

What is board-level repair?

It means diagnosing and repairing faults on the main circuit board instead of only replacing external parts.

Is motherboard repair always worth it?

Not always. TECHHELP considers fault severity, device value, data importance and replacement cost before advising.

Can liquid-damaged boards be repaired?

Sometimes. Success depends on corrosion level, how quickly the device was powered off and whether critical circuits are damaged.

How long do advanced diagnostics take?

Board-level diagnostics can take longer because the fault must be traced carefully before a reliable quote is given.
