ABB HMI panel repair and refurbishment.
Board-level diagnostics and component-level repair for ABB CP600 and Panel 800 operator panels. Engineer-led, no fix no fee.
ABB panels
ABB HMI panels appear across UK process industries, water treatment plants, and power generation facilities. The CP600 series uses aluminium enclosures that are moderately serviceable, while the legacy Panel 800 (PP846) has membrane keypads available from aftermarket suppliers. As these units often operate continuously, backlight-related failures are increasingly appearing on earlier CP600 installations.
Common faults we fix on ABB panels
-
LED backlight degradation on CP600 panels — particularly on units in continuous 24/7 operation after extended service
-
Resistive touchscreen wear and calibration drift on CP600 models after extended industrial service
-
Membrane keypad degradation on legacy Panel 800 (PP846) units with worn or unresponsive buttons
-
Power supply and capacitor faults causing intermittent operation or failure to start on both CP600 and Panel 800 series

ABB HMI panel repair FAQs
Which ABB HMI panels do you repair?
We service the CP600 series (CP620 through CP676) and the legacy Panel 800 (PP846). Contact us with your specific model and we will confirm the repair scope.
Can you replace the membrane keypad on an ABB Panel 800?
Yes. Aftermarket membrane keypads are available for the PP846 Panel 800. We source compatible replacements and carry out the swap with functional verification before return.
My ABB CP600 screen is dim — can you repair it?
Yes. A dim screen on a CP600 typically indicates LED backlight degradation. We diagnose the backlight circuit and carry out the necessary repair or replacement.
