检测与消亮两电路的探讨

The Probing of Detect Circuit and Clear-Bright Circuit

采用人体电阻分压式偏置方式检测三极管,能有效地避免测量过程对元件的损坏;对长虹R2118A消亮电路作用进行分析、探讨,并提出了自己的见解.

This article is about the pop measuring operation of the quality of transistor and the probing of Clear-Bright circuit in the TV set, ChangHong R2118A. It is suggested that measure by body-resistor divided-voltage mode to avoid deformation to the components through measuring progress. Then author expounds his own viewpoint to Clear-Bright circuit.
