将电源(24)脚和④脚排插分别对应插到主板上的插座,通电试机时,电源指示灯时亮时灭,电源风扇和CPU风扇都时转时停,蜂鸣器无通电自检声。测电源各输出脚与地间电压,除紫线与地间电压为稳定的5V,绿线与地间的电压为稳定的,其余各脚与地间的电压都在不停地跳变,说明主板中存在严重的短路故障,拔掉光驱和硬盘的数据线和电源线,通电故障不变。取下CPU和内存条通电,电源风扇时转时停,CPU风扇不转。插入内存条,试短路绿黑线,电源风扇高速旋转,CPU风扇不转,试摸主板各芯片,发现SWSCSOH5514E-NSE0810-A404158S1332860烫手,立即断电。检测数据说明,同一个厂家的不同主板,虽然使用电压相同的电源供电,但其供电脚与地间的正向电阻却相差很多,且供电脚与地间的正反向电阻有时相同,有时相差很大。用测主板各供电脚与地间的正反向电阻查出该主板的短路故障难度很大,只能用测大功率管和各晶体管PN结的正反向电阻来寻求突破。用DT830B数字万用表二极管挡测完主板上的所有晶体管,发现Q55(N790A-EF814)的②脚与③脚间正反向电阻都为4Ω,Q54(N790A-EF814)的②脚与③脚间正反向电阻都为3Ω,Q52(748T40N03G)的②脚与③脚间正向电阻为llΩ,反向电阻为12Ω。 压电蜂鸣片由锆钛酸铅或铌镁酸铅压电陶瓷材料制成。
