After-Sales Support

HuiSoar usually responds to support requests within 24 hours on working days. To help us provide faster assistance, please include the product model, order details, application, issue description, photos, videos and any related datasheets or connection diagrams.

Please provide the LCD panel model, controller board model, cable photos, power supply information, input signal type, operating environment and a clear description of the issue. Photos or videos showing the display problem can help our engineering team identify whether the issue is related to the panel, cable, controller board, interface, power supply or system settings.

Yes. HuiSoar can assist with controller board matching, interface confirmation and basic signal compatibility checks for LCD panels and display modules. If you provide the panel model, datasheet or existing connection details, we can help evaluate suitable controller board, cable and interface options.

If the original LCD panel or display component is unavailable, discontinued or not suitable for your project, HuiSoar can help search for replacement or alternative models. We compare key specifications such as size, resolution, active area, outline dimensions, brightness, interface, connector position, operating temperature and mechanical fit.

HuiSoar can help customers check stock availability, alternative models and possible replacement options for discontinued or hard-to-find LCD panels. For long-term projects, we recommend confirming model availability early and preparing alternative solutions to reduce future supply risk.

You can request datasheets, specifications, drawings, interface details, controller board information and application references from HuiSoar’s sales or support team. These documents help customers confirm product parameters, installation requirements and compatibility before sample testing or mass production.

Please first check the power supply, cable direction, connector position, controller board, input signal and backlight connection. If the issue remains, send photos of the full connection setup, product labels and any test results so our team can help identify whether the issue is caused by incorrect wiring, incompatible signals, power mismatch or product failure.

Display abnormalities may be related to cable connection, signal timing, controller board settings, power stability, panel damage or system compatibility. Please provide videos, close-up photos, the panel model, controller board model and input signal information so HuiSoar can help analyze the issue and suggest the next inspection steps.
