一台康佳T2114彩电(TA8611+TA8759AN机芯),出现图像暗且无彩色故障。首先,排除无彩色故障,测N701(TA8759AN)⑦脚(色饱和度控制端)电压,发现在调节色饱和度时电压能在1.1~1.7V之间变化(正
A Konka T2114 color TV (TA8611 + TA8759AN movement), the picture appears dark and no color failure. First of all, to eliminate non-color failure, measured N701 (TA8759AN) ⑦ foot (color saturation control terminal) voltage and found that the voltage can be adjusted between 1.1 ~ 1.7V when the color saturation
