二手彩电大致可分为以下两类:第一类是显像管良好、机芯电路未经多次、大规模维修者,这类机器声图效果良好,剩余寿命较长,即使日后出现电路故障,也比较便于维修,因而只要价格划算,可以购买。第二类是显像管已经老化或机芯电路经多次、大规模甚至是破坏性维修,这类机器效果很差,剩余寿命很短,即使价格低廉,也不宜购买。本文着重就有关显像管的老化特征、雨生以及效果等问题谈一点一家之见,供
Second-hand color TV can be broadly divided into the following two categories: The first category is a good tube, the movement of the circuit without many, large-scale maintenance who sound good effect of such machines, the remaining long life, even if the future circuit failure, but also More easy to repair, so as long as the price is good, you can buy. The second category is the tube has been aging or movement of the circuit after many, large-scale or even destructive maintenance, such machines are poor, the remaining life is very short, even if the price is low, it should not be purchased. This article focuses on the aging characteristics of the CRT, rain and effects and other issues talk about the views of one by one for
