AI Technical Summary

Benefits of technology

This technology allows for detecting when an electronic component (TV) board starts up or stops working properly during its operation period without being connected into another system's interface. It then checks this status before entering any specific testing tools like voltage comparators. If there are no connections between components at all times, they will work correctly with these testers.

Problems solved by technology

This patented technology allows for different interfaces on televisions without requiring separate tools or testing them separately from other components like audio/video devices.

Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] In related technologies, with the development of display technology and the continuous requirement of cost reduction, the display interfaces of TV sets show a trend of diversification, among which the main interface types are vbyone, lvds and tconless. As for the TV, the main board of the TV needs to be inspected for screen parameters during production, but since each interface type requires a corresponding interface inspection tool, the inspection operation can be performed. And when producing TV motherboards, it is often impossible to prepare screen tooling with multiple interface types to detect TV motherboards with multiple interface types. As a result, the factory is not conducive to rapid production change and the production of the same product in different factories due to the non-universal testing tooling.

Abstract

The invention discloses a television mainboard detection method and device, a television mainboard and a medium, and belongs to the field of televisions. The television mainboard detection method comprises the following steps: when the television mainboard is powered on and started, detecting the current state of the first reserved port; and if the pre-stored low-voltage differential signal data is not in the preset state, outputting the pre-stored low-voltage differential signal data, so that the television mainboard detection equipment identifies and displays the pre-stored low-voltage differential signal data. According to the invention, universality of different detection tools can be realized.
