色度延迟线开路或短路后,电视机会出现彩色爬行“或彩色失真故障。色度延迟线是否短路损坏,可通过”电阻测量法“来判断。用万用表R×10 kΩ档测量色度延迟线各引脚之间的电阻值,正常时均应为∞(无穷大)。若测得某两只引脚之间有一定的电阻值或阻值为0Ω,则说明该延迟线已漏电或短路损坏。亮度延迟线开路损坏,用万用表无法测出,只能用”元件代换法“来判断。色度延迟线损坏后,应更换同规格、同型号的色度延迟线或用性能相近(例如相位延迟时间、中心频率等参数应相同)的其他型号色度延迟线代换。
Chromaticity delay line is open or short circuit, the TV will appear color crawl ”or color distortion failure. Chrominance delay line is short-circuit damage, by “ resistance measurement method ”to determine the use of multimeter R × 10 kΩ file color measurement Degree delay line resistance between the various pins, normal should be ∞ (infinity). If measured between the two pins have a certain resistance or resistance is 0Ω, then the delay line has been leakage Or short-circuit damage. Brightness delay line open circuit damage, can not be measured with a multimeter can only be used “Component Substitution ” to judge. Chroma delay line damage, should be replaced with the same specifications, the same type of colorimetric delay line or Replace with other types of chromaticity delay lines with similar performance (for example, parameters such as phase delay time and center frequency should be the same).
