Overview
What is industrial electronics repair?
Industrial electronics repair means fixing the actual faulty component instead of discarding the whole unit. We locate the specific failure (IGBT module, DC-link capacitor, power supply, control board, backlight, encoder) and replace it precisely. This is a fraction of the cost of a new device — and for obsolete models, often the only option.
We are brand-independent. We repair all major manufacturers across VFDs, PLCs, servo drives, HMI panels and CNC controls. Our team has 15+ years of industrial electronics experience in diagnostics and repair, and handles technical correspondence in English.

Repair process
4 steps to operational
Every unit goes through this process. Detailed quotation before any repair — no surprises.
1
Intake
Intake, documentation, condition photos. Replaced parts returned on request.
2
Diagnosis
Fault-code readout, measurement, thermal imaging, oscilloscope — typically 2–4 business days. Detailed quotation before any repair.
3
Repair
Component-level replacement with original or qualified parts. Cleaning and conditioning.
4
Functional test
A powered-on functional check per the vendor's test procedures: parameter consistency, fault-free state. Returned ready to run.
Repair or replace?
New purchase vs. repair
In most units the fault is a single inexpensive component — replacing the whole device is often unnecessary cost.
Buying new
- High purchase price, especially at higher power
- Weeks-to-months lead time for some models
- Obsolete types no longer available
- Re-parameterisation and commissioning cost extra
- The existing, proven installation is wasted
Repair at IEM
- Repair is typically a fraction of the new price
- Inspection in 2–4 business days; express option for contract partners
- Solution for obsolete / discontinued types too
- Program backup and restore, parameter retention
- 12-month warranty on the repair
FAQ
Frequently asked questions
Do you correspond in English?
Yes. Our team handles technical correspondence (fault description, quotation, findings) in English. The detailed device and knowledge-base pages on the site are in Hungarian, but you are welcome to contact us in English.
Can you repair units from outside Hungary?
Yes. We are based in Érd, near Budapest. Units can be shipped in from abroad, and we carry out on-site repair across Hungary and in neighbouring countries — Austria, Slovakia, Romania, Serbia, Croatia and Slovenia. For EU customers, shipping the unit in is usually the fastest route; please contact us to arrange the details.
What does a repair cost?
The exact price depends on the fault and the type, so we provide a detailed, itemised quotation after inspecting the unit — before starting any work. The inspection is free of charge if you order the repair or a replacement unit from us; if you order neither for a repairable unit, a pre-stated inspection fee plus shipping applies. No surprise invoice.
Do you repair obsolete / discontinued equipment?
Yes. Component-level repair of obsolete types is often the only viable route, since new units are no longer available. We accept these too.
What is the warranty?
We provide a 12-month warranty on every completed repair. Each unit is functionally tested in powered-on state before return.
How do I send a unit in?
Send the unit by courier or post — no need to visit in person. Include the type, the fault symptom and a few photos to speed up the diagnosis and quotation.
