Circuit Repair

Sometimes a HMI fault isn’t as simple as a touch screen or dim display, it can be due to components faulting on the circuit boards within the unit, Lisstech perform component level diagnostics in order to find the fault and fix it as efficiently as possible.


Maintenance and Servicing

If a machine is down for maintenance then Lisstech can put a 12 month warranty on any repair sent in for an overhaul/service, this includes any electronic repair whether it be HMI or another type of unit.

About Our HMI Repairs

More often than not, a HMI fault is due to time or wear and tear and customers may deem it to be scrap and replaceable, however this is not cost effective as for a fraction of the price the unit can be given a new lease of life. Units return back looking brand new, with top quality appearance and performance.

How we quote a repair

A fully qualified engineer will strip down and assess the unit, hopefully with a fault description from the customer and put together a quote of estimated time needed and parts costs. This will then go to a sales quote whereby other factors such as courier cost and urgency are included. Finally the quote is emailed over and the job awaits acceptance.

Assessments performed

While a repair won’t be carried out before a quote is given a go ahead, the engineer will look quite deeply into what parts will be needed and where they can be ordered from to ensure the repair is carried out as quickly as possible when a go ahead is given.

If you feel a repair has not been carried out to the high quality Lisstech standard then please contact us and give us feedback.

Typical HMI Faults

The majority of HMI faults are caused by wear and tear, or simply time taking its toll on components inside the unit.
