更换行输出的注意事项

  行输出在彩电里起着一个很重要的作用，不但要供给显象管的所需电压，还有通道电压的供给！
行输出的生产厂家也很多，大厂的质量可靠性比较好，但是价格比较高，而那些小作坊似的小厂也同样可

以生产！因为价格很便宜，市场也同样有立足地，但是质量很差！即使在同一种规在参数上有的也有悬殊

！
所以在更换行输出的之前仔细核对各脚的参数，还有就是把加速聚焦调到最低，上好后不要马上就上到显

象管上，用万用表检测一下灯丝电压，机械表测量大约有4V交流电压！这样可以上好，然后先把加速电压

逐渐调大，然后再调聚焦，直到雪花点颗粒最细！
还有就是要样成一看二摸的习惯，一看就是看灯丝亮的颜色，一般为橘红色，二摸行管的温度，温度一般

为和体温差不多，温乎！
