Component-Level Repair
Experienced engineers repair to component level using quality-matched parts and controlled soldering.
Functional Testing
Every unit is powered up and tested per equipment requirements before sign-off.
Installation & Commissioning
We refit, parameterise and commission on site, verifying the line runs to spec.
Warranty & Report
You get repair warranty as per our service terms and a written service report for your maintenance records.

Common Faults & Fixes
Black screen but backlight on (Weintek/Delta)
Cause: Corrupted firmware after unclean power-down, or LCD flex cable failure
Fix: Recover via USB firmware boot, reseat LCD flex, and replace touchscreen LCD panel if artefacts persist.
Ghost touch / phantom taps
Cause: Damaged resistive touch overlay or moisture ingress at gasket
Fix: Replace touch overlay assembly, reseal cabinet gasket, and enable touch-calibration on boot.
Communication error with PLC
Cause: Baud rate / parity mismatch, damaged RS-485 driver, or PLC IP change after reprogramming
Fix: Verify serial parameters, swap MAX485 chip on HMI comms board, and lock PLC IP in HMI driver settings.
USB backup fails to load
Cause: FAT32 partition scheme mismatch or firmware upload lock enabled
Fix: Reformat USB to FAT32 (small allocation unit), disable upload lock via engineering password.
Backlight dim / flickering
Cause: Aged LED backlight bar, worn boost converter caps on the LCD board
Fix: Replace backlight LED strip, reflow / replace boost cap, and confirm brightness setpoint.

Recent Job Snapshot
Context
A leading food-processing plant near Medchal operating a critical GOT2000 GT27 on a filling line line
Fault
Ghost-touch causing false product changeovers traced to moisture ingress at the cabinet gasket — new gasket + touch overlay + firmware refresh restored full function
Action
Our team performed component-level diagnosis and repair on our bench with post-repair functional testing per equipment requirements.
Outcome
GOT2000 GT27 on a filling line restored to full spec inside 96 hours from breakdown call, avoiding an OEM lead time of 6-8 weeks and saving an estimated ₹8 lakh in production loss.
