维修时注意焊锡条!
在维修的时候,经常用到焊锡,但是在用焊锡的时候会否发现,一般都是一整条一拉出来就用来焊电路板
的.那可要注意了,因为电视机中有的高压电容可能还充有很高压的电压(比如电源的滤波电容,200
V的滤波,等等.),你把焊锡一条拉出来就用来焊高压电容,那整条焊锡都会带有比较高压的电,如果
那条焊锡还碰到其它的地方,如:CPU,解码等等的引脚,就有可能造成人为的电击损坏元件的故障造
成不必要的损失.
还有那焊锡在焊的时候会发生小小的爆声,会把一些小的焊锡浅到其它的电路上,引起短路,所以在修好
机后最好有牙刷刷一下,看一看有没有小焊锡.
对于烙铁嘴上的焊锡,多了就要及时清理,过多了会掉到电路板上,掉到那些隐蔽的地方短路了就麻烦了
