Description

Board-level repair of the integrated control box, digital motor driver and panel on the Jack A4F. The A4F computerised lockstitch runs digital motors from an integrated controller. Loose motor connectors under vibration are a frequent root cause of driver damage.

Send the board to our Bangalore workshop with the ₹800 inspection charge. We diagnose the fault and quote the repair before any work starts. The inspection charge covers the diagnosis and is retained whether or not the board can be repaired.

Turnaround is 6 working days from receipt, and every completed repair carries a 3 month warranty on the work done.
