例1 型号:N10型万利达VCD机故障现象:开机能正常放清晰图像,只是在蓝底状态时显示为绿色。分析与检修:由于能放正常图像,因此故障范围仅是基色输出通道有异常,测量R、G、B三基色输出通道,结果发现G (绿)基色电平较高,查其相关的元件,结果发现电容C_(68)漏电,换之试机故障排除。例2 型号:N10型万利达VCD机故障现象:不能读盘分析与检修:拆开机壳不放入碟片开机,发现光头
Example 1 Model: N10-type Malata VCD machine failure phenomenon: boot can put a clear image, but only in the blue state when the display is green. Analysis and Overhaul: As the normal image can be put, so the fault range is only the primary color output channel is abnormal, measuring the three primary color R, G, B output channel and found that the G (green) primary color level, check the relevant components, Found that the capacitor C_ (68) leakage, replace the test machine troubleshooting. Example 2 Model: N10-type Malata VCD Machine failure phenomenon: can not read the disk analysis and maintenance: open the case do not put the disc boot, found bald
