检查电源IC负载与阻值解决加电不启动问题

检查开机问题

在检查开机问题时，先依据原理图对J0801的第9脚进行开机触发电压的测量，发现实际电压为0V，而预期应为1.8V。进一步检查该脚与地之间的阻值，结果显示无穷大，显然存在异常，可能通路存在问题。为了深入探究，又测量了通路中的FL0819对地阻值，同样发现阻值无穷大。

▣ 替换电感解决问题

在更换了一个电感后，重新测量触发脚对地阻值，结果显示正常。随后加电开机，电流表现正常，最终成功看到了期待已久的开机画面。

02处理电源IC故障

若出现加电不漏电，但按下开机键后漏电的情况，这通常指示电源IC的某一路负载存在短路。

▣ 发现短路问题

为了定位问题，我们需要逐一测量电源IC各路输出的对地阻值，直至找到短路点。

▣ 通过测量定位短路

确定短路位置后，可以利用松香来进一步定位具体的损坏部件。接下来，我们将目光转向电源IC的各路输出，通过测量每路旁路电容的阻值，来逐步缩小故障范围并找到短路的具体位置。
