Product Description
Are vertical or horizontal lines appearing on your HMI screen, obstructing critical information? These lines can be distracting and indicate a developing hardware problem. ROC Industrial specializes in diagnosing and repairing HMIs with lines on the screen. Our technicians identify whether the issue is with the LCD panel, internal connections, or control board, providing effective repair solutions.
Is Your Device Showing These Signs?
The most frequent repairs for this part number involve addressing failures in the LCD panel, specifically pixel defects manifesting as lines or distorted images on the HMI screen. We commonly resolve issues stemming from backlight malfunctions, often caused by faulty inverters or LED arrays, resulting in dim or non-existent display illumination. Furthermore, we repair failures within the graphics processing unit (GPU) or associated video memory, which can cause screen artifacts, freezing, or complete display failure. Finally, we address connectivity problems arising from damaged ribbon cables or connectors linking the LCD panel to the main board, leading to intermittent or absent video signals.
Technical specifications
The appearance of persistent vertical or horizontal lines on an HMI screen is typically symptomatic of a fault within the LCD panel itself (e.g., driver IC failure, broken row/column connections within the panel) or issues with the flexible printed circuits (FPCs) or ribbon cables connecting the LCD panel to the main logic board or T-Con board. Less frequently, a failing T-Con board or main video processing circuitry can manifest as lines. Our repair involves careful inspection of these connections and, if necessary, replacement of the entire LCD panel assembly if the fault is internal to the panel.
Our Repair Process for the
Repair Service
Our repair process begins with a comprehensive diagnostic assessment to pinpoint the precise failure within the HMI unit. The most frequent repairs address failures in the LCD panel, specifically pixel defects manifesting as lines or distorted images on the HMI screen. We resolve issues stemming from backlight malfunctions, often caused by faulty inverters or LED arrays, resulting in dim or non-existent display illumination. Failures within the graphics processing unit (GPU) or associated video memory, which can cause screen artifacts, freezing, or complete display failure, are repaired. Connectivity problems arising from damaged ribbon cables or connectors linking the LCD panel to the main board, leading to intermittent or absent video signals, are addressed. Following the diagnosis, we execute component-level repairs or replacements using only verified, high-quality components, followed by rigorous testing to ensure complete functionality and adherence to original performance specifications.
