检修夏普NC—Ⅱ T机芯,一定要熟知其机理与检修方法,才能取得事半功倍的效果。否则如本例那种“头痛医头,脚痛医脚”的检修,而不去进一步查找导致故障根源,犹如“一叶障目,不见泰山”,不但不能彻底排出隐患,反而会进一步扩大故障范围。一、JC—Ⅱ T开关电源的特点 1.它由电源厚膜IC_(701)(IX0699CE)和外围电路组 Maintenance of Sharp NC-Ⅱ T movement, we must be familiar with its mechanism and maintenance methods, in order to achieve a multiplier effect. Otherwise, as in the case of “headache, foot pain,” the overhaul, without going to find the cause of the root cause of the malfunction, like “a leaf barrier, not seen”, not only can not completely drain the hidden dangers, but will further expand the scope of failure. A, JC-Ⅱ T switching power supply features 1. It consists of thick film power IC_ (701) (IX0699CE) and the peripheral circuit group
