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!

Well, earlier, the reward bit was really talking about the carrot and now it is talking about the stick. The carrot is playing on the emotion of euphoria and hope, two really very powerful ways that wow power leveling you can persuade someone.
So we wow power leveling have talked about those two warcraft gold emotions, and now we will be moving on to two more and they have to do with wow gold the concept of the stick, which is a concept of aion power leveling punishment.Take this, if not you will be dropping like flies in a few years. Or do not eat this, or else your kidneys aion gold will turn into paper. So there are really cheap wow power leveling many ways you can use scenarios and the power of fear to your own advantage. Punishment is a great way for you to persuade someone buy wow power leveling to do what you want them to do so try and learn and refine the art, adding your own unique perspective on it. Soon, people will be eating from your hand.
