贵刊2005年第8期刊发了于振麒的《电容漏电引发——奇特故障与不解》一文。文章摘要“:C2588型长虹彩电,亮度、对比度调大时,伴音音量会随之减小。图像亮度忽明忽暗时,音量会随之忽小忽大,不失真。直观判断主电源带载能力减弱。先后检测TA8211(伴音功放块)供电电压2V,正常无波
Your issue No. 8, 2005 issue Yu Zhenqi’s “capacitive leakage caused - strange failure and puzzled,” a text. Article Summary ": C2588 Changhong color TV, brightness, contrast is large, the sound volume will be reduced.When the brightness of the image flickers, the volume will then suddenly small, without distortion. Intuitively determine the main power with load Ability weakened .Taiwen TA8211 (sound amplifier block) power supply voltage 2V, normal wave
