走字灯箱全都花了

我做了第一个走字灯箱可是刚开始还好，只有几个地方有不该着的灯着了，我仔细检查发现有的灯珠用万用表量全通了！估计是在加工的时候被静电击穿了！我开是换，换了大概有100多个（我做的是16X96的）可是还完后更花了，我现在都不知道是什么原因，我在检查时发现几乎所有的灯都坏了！我现在不知道是什么原因，请大家帮忙找找原因！

看看是不是什么地方绝缘没有搞好，引入了市电了

老大详细说说，我以后也可以注意啊

仔细检查过了！发现多数灯击穿了！更换后问题解决！但是不知道为什么会击穿，我估计是静电太大了！目前我没办法解决！

呵呵，不是没办法解决，估计你什么地方引入了市电，只是你没有觉察出来

应该不是坏了，我也遇到过 我这个跟你那个一摸一样的效果 不过 我把背板去掉 敞开着就没事！

新手问题多多，我好害怕啊，不敢入手了都。

学习中,多检查,多总结,不要急着通电.

是的,没错,多检查,不要急着通电.

多看论坛，做的时候仔细点，先做小点的，不然亏大发了

我做的每个都会出现烧毁的情况，郁闷

是不是电烙铁绝缘不好了？

测量输出电压了没有，是否正常 1# 丹顶鹤

学习中,多检查,多总结,不要急着通电

学习啦，新手入门！好怕怕哦

好可怕啊！！！！！！！
