HMI Display Repair Solution — Proface AGP3550-DISP D05044A | AGP3550 Series
Where This Product Is Used
The Proface AGP3550-DISP D05044A circuit board is the core display driver assembly for the Proface AGP3550 series HMI (Human-Machine Interface) panels. It is deployed across a wide range of industrial environments where reliable operator interface is mission-critical:
- Automotive manufacturing lines — press control stations, robotic welding cells, and conveyor management panels
- Food & beverage processing — SCADA-connected HMI terminals for batch control and CIP monitoring
- Pharmaceutical production — GMP-compliant operator panels in cleanroom environments
- Water treatment & utilities — remote pump station HMIs and SCADA visualization terminals
- Plastics & injection molding — machine parameter display and alarm management interfaces
- Semiconductor fab equipment — process recipe display and interlock status panels
- Oil & gas field instrumentation — wellhead control panel HMI displays
When the AGP3550 display fails — showing white screens, backlight failure, pixel dropout, or touch misalignment — this D05044A board is the OEM-equivalent replacement that restores full panel functionality without replacing the entire HMI unit.

Why Engineers Specify This Model
- Exact OEM form factor — drop-in replacement with no mechanical modification required; all connector positions match the original AGP3550 chassis
- Cost-effective repair path — replacing this board costs a fraction of a full HMI panel replacement, preserving existing wiring, mounting, and programming
- Eliminates display-specific faults — directly addresses white screen, backlight failure, color distortion, and display freeze without touching the CPU or I/O modules
- Minimizes downtime — board-level swap can be completed in under 30 minutes by a qualified technician, versus days for full panel procurement and reconfiguration
- Preserves existing PLC/SCADA integration — no re-programming of GP-Pro EX projects or communication settings required after replacement
- Sourced from verified supply chain — Konmask stocks boards from traceable industrial surplus and authorized distribution channels

Application-Specific FAQ
Q: Will this board work with all AGP3550 variants?
A: The D05044A is designed for the AGP3550 display assembly. Confirm your panel’s internal board revision label matches before ordering. Contact us if you are unsure.
Q: Do I need to re-flash or reconfigure anything after replacing this board?
A: No. The D05044A is a display driver board only — it does not store project data or communication settings. Your GP-Pro EX project and PLC connections remain intact on the CPU board.
Q: My AGP3550 shows a white screen — is this board the cause?
A: White screen on AGP3550 is commonly caused by a failed display board or backlight inverter. The D05044A replacement resolves the majority of white-screen faults. If the issue persists after replacement, the LCD panel itself may also require replacement.
Q: Can Konmask supply multiple units for a planned maintenance stock?
A: Yes. We support bulk and blanket orders for MRO stocking programs. Request a volume quote via email.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 7–21 business days depending on sourcing. Contact us for real-time availability.
