2006年第10期问与答栏目问3中提到一台康力彩电CE-6468-1B彩电,在更换行输出变压器及“行管”后图、声正常,但没有字符显示,调亮度色彩无反应故障。我个人也曾遇到过类似的故障。一台日松电视机(A3机心),110V供电,行输出短路造成自动关机,更换行输出后声、像正常,就是无开机“欢迎”界面,也无字符(字符散乱,偏向右边),并且无规律地自动关机。如果拔下天线再插上出现白屏,声音正常。查行、场脉冲均加在CPU
Question and answer column Question 3 mentioned in a Connaught color TV CE-6468-1B color TV, the output line in the replacement of the output transformer and “after” figure, the sound is normal, but no character display, tune Brightness color no reaction failure. I personally have encountered a similar failure. A Nissan TV (A3 movement), 110V power supply, the output short circuit caused by automatic shutdown, replace the line output after the sound, as normal, there is no boot “Welcome ” interface, there is no character ), And automatically shut down irregularly. If you unplug the antenna and then plug in a white screen, the sound is normal. Check line, field pulse are added in the CPU
