Completed repairs / sample cases

These samples illustrate typical lab work. Images are placeholders until real workshop photos are available.

Industrial control board repair

Device
Industrial control module
Fault
Would not power on after a voltage spike
Work performed
Internal supply review, damaged parts replaced, bench validation.
Outcome
Tested before hand-off with currents within range.

Every fault needs its own diagnosis; this sample is illustrative.

Water pump electronics check

Device
Peripheral pump with electronic command
Fault
Intermittent starts and reported thermal trip
Work performed
Measurements on command stage, sensors and output relays reviewed.
Outcome
We reported repair viability and alternatives when the winding was compromised.

Final decision depends on mechanical state and usage history.

Switching power supply repair

Device
Medical-grade switching supply
Fault
Unstable output causing system resets
Work performed
Critical electrolytics replaced and feedback adjusted after verification.
Outcome
Voltages stabilized under moderate load testing.

Sealed or potted supplies may not be serviceable.

Electronic temperature controller

Device
PID temperature controller
Fault
Heater output stuck on
Work performed
Power stage inspection, soldered relay replaced, isolation verified.
Outcome
On/off cycles regular without abnormal overheating in test.

If internal traces are damaged we compare recovery vs replacement.

Motor drive inspection

Device
Three-phase motor with compact integrated drive
Fault
Drive stuck in permanent alarm
Work performed
Input stage diagnostics, bus capacitors and cooling reviewed.
Outcome
Detailed report before replacing costly semiconductors.

Motors without electronics are referred when appropriate.

Home appliance board

Device
Washing machine PCB
Fault
Programs stopping with intermittent error lights
Work performed
Valve and sensor measurements, auxiliary supply check and optic cleanup.
Outcome
Simulated wash cycle in lab without full laundry load.

Home results may vary with installation and usage.

Drone repair

Device
Practice multirotor drone
Fault
Arm dead after a crash
Work performed
ESC continuity, bead inspection and damaged MOSFET replaced.
Outcome
Motors spin synchronized on bench without props; flight verified by owner.

Severely damaged IMUs may require full replacement.

Connector and trace restoration

Device
Automation PCB
Fault
Moisture corrosion near terminal block
Work performed
Controlled cleaning, trace bridges and degraded connector replaced.
Outcome
Critical field signals recovered per supplied schematic.

Prior moisture may leave residual risk — we always disclose it.
