问1:康佳PDP4601等离子彩电,开机后红色指示灯亮,随后绿一下熄灭,出现无光栅、无伴音、无图像,如何检修?答:从故障现象分析,该故障可能是等离子显示屏电路供电异常,引起电源电路自动保护造成的。分别检查X驱动板(电压处理板)、Y驱动板(电压处理板)和电源板,怀疑电源板存在故障,用代换法替换电源后,故障消失,说明电源板存在故障。更换电源板后,故障即可排除。
Question 1: Konka PDP4601 plasma TV, turn on the red light, and then turn off the green, there is no grating, no sound, no images, how to repair? A: From the failure phenomenon analysis, the failure may be plasma display circuit power supply anomalies, Caused by the power circuit automatically protected caused. Check the X drive board (voltage processing board), Y drive board (voltage processing board) and the power board respectively. If there is any fault on the power board, replace the power supply by the substitution method and the fault disappears, indicating that the power board is faulty. Replace the power board, the fault can be ruled out.
