一般彩电末级视频放大电路无论是分立元件还是采用集成电路,其RGB三基色视放均为三个独立的基色通道,当某一路元件出现故障时,表现为图像缺色或偏色,但具有自动自平衡校正(即AKB功能)的电视机,表现出的故障却不同,以下是一检修实例。故障现象:在收看过程中突然无光,但伴音一直正常。
General color TV final video amplifier circuit Whether discrete components or the use of integrated circuits, the RGB three-color video playback are three independent primary color channel, when a component failure, the performance of the lack of color or color cast, but with Automatic self-balance correction (AKB function) TV, showing the fault is different, the following is a maintenance example. Symptoms: Suddenly no light in the viewing process, but the sound has been normal.
