例164康佳T2910A型彩电故障现象:开机后屏幕出现一条水平亮线,但伴音正常。分析与检修:测TA8659AN!“#、%$、’()脚电压,异常,再测+,*脚电压为正常的11V,检查TA8659AN./-脚锯齿波形成电容C321良好,查为VD301击穿短路。更换VD301后,故障排除。例165康佳T2910A型彩电故障现象:接
Example 164 Konka T2910A color TV Fault phenomenon: After the boot screen appears a bright horizontal line, but the sound is normal. Analysis and Overhaul: Measure TA8659AN! ”#,% $, ’() Voltage of foot, abnormal, retest +, * foot voltage is normal 11V, check TA8659AN. --- foot sawtooth waveforms form capacitor C321 good, check as VD301 Break through the short circuit. After replacing VD301, troubleshooting. Example 165 Konka T2910A color TV Fault phenomenon:
