Precision begins with understanding the problem

Every device and every fault requires an individual assessment. That is why I begin with diagnostics and only then present the possible solution and estimated cost.

I repair both common faults, such as a damaged screen, battery or charging port, and complex motherboard problems that require microsoldering.

“Precision begins with understanding the problem.”

I focus on direct communication, a clear explanation of the fault and a solution matched to the condition and value of the device.

Core principles

01

Diagnosis

First I identify the cause of the problem, then I propose the repair.

02

Transparency

I agree the scope and cost before starting the actual work.

03

Accuracy

I use the right equipment and verify the result of the completed service.

04

Communication

I explain the problem and the available options in plain, understandable language.

Facilities and specialisation

Service workstation

For repairs I use a microscope, microsoldering equipment and diagnostic tools required for working with modern phones.

  • a service microscope,
  • equipment for soldering SMD and BGA components,
  • measurement and diagnostic tools,
  • a workstation for safe electronics work.

Repairs I show

On the website and blog I publish selected repair cases: screen replacements, power and touch-control circuit repairs, and other motherboard work.

This lets you see not only the finished phone, but also the scope and nature of the work carried out.
