例97康佳T2530D型彩电故障现象:开机无伴音,屏幕无图像只有较暗的蓝光栅。分析与检修:测CPU(ST6367)“#!脚(工作电源端)、%$脚(复位端)直流电压均为5V左右,再测ST6367时钟振荡端()’、*+,脚直流电压分别为0V、2.6V(正常应分别为2.4V),检查相关元件,发现晶振Z601损坏。更换Z601
Example 97 Konka T2530D-type TV failure phenomenon: boot no sound, the screen no image only dark blue grating. Analysis and Overhaul: Measure CPU (ST6367) ”#! Feet (work power side),% $ feet (reset side) DC voltage is about 5V, then test ST6367 clock oscillation side Respectively, 0V, 2.6V (normal should be respectively 2.4V), check the relevant components and found damaged crystal Z601. Replace Z601
