一台辗转来此的彩电(长城JTC471—2A型,X56机芯)彩色奇怪,画面中是绿脸、红草地,典型的“红绿反转”。早年的全晶体管式彩电中,这种故障司空见惯。自打采用集成色度解码块以后,“红绿反转”近乎绝迹,看来不是原发故障。果然客户说:此机原来经常放不出彩色,经人修过就变成“红绿反转”,多次换件也修 One was removed to the color TV (Great Wall JTC471-2A type, X56 movement) strange color, the picture is a green face, red grass, a typical “red and green inversion.” Early all-transistor TV, this failure is commonplace.
