The fixed repair price refers to a device that has not yet been opened and is thus in an original state.
Unsuccessful previous repair attempts usually result in more effort and thus in additional costs.
Extensive oxidation damage or damage caused by internal overvoltage may require more labor.
In such cases, we will discuss the costs with you before beginning any repairs.
