不知道大家在测量正常CPU的时钟晶振输入端(时钟振荡输出端不起作用)电阻时注意到没有:测量过程,电视机反而不能正常工作,由正常收看状态会转变为自动关机或其他状态,其中道理也是一样的:那就是这个感应分布电容会并联在CPU(31)脚与地之间的振荡电容C605上,使振荡电容量无形加大,使时钟振荡频率发生变化(应该是频率降低),造成CPU不能正常工作了。
I do not know everyone in the normal CPU clock oscillator input (clock oscillation output does not work) resistor noticed: the measurement process, but the TV can not work normally from watching the state will be turned into automatic shutdown or other state, The reason is the same: that is, the sensor capacitance will be paralleled in the CPU (31) between the feet and ground oscillation capacitor C605, the oscillation capacitance invisible increase, the clock oscillation frequency changes (it should be lower frequency) , Resulting in the CPU can not work properly.
