Instrument for detecting flat-plate television failure and detection method thereof

Abstract

The invention relates to television technology, solves the problems that the fault detection and the positioning of the prior panel television are complicated, and provides a panel television fault detector and a detection method thereof. The technical proposal can be summarized as follows: the panel television fault detector comprises a power supply module, a digital signal input interface, an analog signal input interface, a multi-way analog switch, an analysis processing control module, a key control module, a liquid crystal display module, a video signal generation module, an audio signal generation module, a remote control signal generation module, a signal output interface and a memory module, wherein each functional module is used to generate each signal of an analog panel television input, and the fault detection for the panel television is performed through detecting the voltage of each detection point of the panel television. The panel television fault detector has the advantages that fault components of the panel television can be determined conveniently and quickly, the fault components are convenient to replace, and the maintenance time of the whole panel television is greatly shortened, thus the panel television fault detector is suitable for the maintenance of the panel television.

Description

technical field [0001] The invention relates to television technology, in particular to the technology of television fault detection. Background technique [0002] At present, the sales of flat-panel TVs at home and abroad are showing a trend of explosive growth, and according to the statistics of relevant organizations, the early repair rate (within 15 days) of flat-panel TVs is as high as 8%. , the high maintenance cost and long maintenance cycle not only increase the operating cost of the enterprise, but also bring great inconvenience to users. If users can get fast, accurate and cheap maintenance services after the failure of the whole machine, it will inevitably Improve the user's satisfaction with the company's brand, thereby bringing a positive impact on the company's brand and providing the core competitiveness of the company's products. The fault detection of flat-panel TVs is generally done by experienced maintenance technicians based on the fault phenomenon, combi...
