六、缺色1.故障原因与检修流程该故障主要是因为:DPTV组件、RGB信号处理电路、视频输出放大器、投影管异常所致,检修流程如图6所示。RGB三基色信号放大通路相同,下面以缺绿色故障为例进行介绍。
Sixth, the lack of color 1. Failure causes and maintenance process The failure is mainly due to: DPTV components, RGB signal processing circuit, video output amplifier, projection tube caused by abnormal, repair process shown in Figure 6. RGB trichromatic signal amplification path the same, the following to the lack of green fault as an example to introduce.
