Quickpanel jr. QPJ2D100L2 P series A Power Supply Repair Service

Professional diagnostic and board-level repair service for this Quickpanel jr. QPJ2D100L2 P series A Power Supply.

QuickPanel Jr. QPJ‑2D100‑L2P is a 5‑inch monochrome touch‑screen HMI used as a compact operator interface in industrial control panels. Common failure points for this model include the internal LCD backlight driver, the touch controller IC, and the power supply board (often a small AC‑to‑DC module). First‑check steps: verify that the panel receives the correct input voltage from its external power connector, inspect the display for any visible burn marks or loose solder joints on the backplane, and test the touch response with a multimeter across the touch sensor traces. If the screen is powered but unresponsive, check the status LEDs or error codes on the HMI menu to isolate a firmware or communication fault. Post Comment
