一、伴音陶瓷滤波器的修复简法电视机修理中,有时这种故障令人讨厌。故障现象是:伴音中发出一种似爆豆的噪声,检查发现是伴音集成块鉴频器调谐回路外接的6.5 MHz的陶瓷滤波器漏电。若无元件调换,可用“电击法”修复。具体方法是:用100V左右的电压对陶瓷滤波器的两极进行瞬间通电。在操作时,动作要快,如果一次不行,可重复多次, First, the sound of ceramic filter repair Jane simple TV repair, and sometimes this trouble annoying. Symptoms are: An audible burst of noise that explodes the beans, checking that it is a leakage of 6.5 MHz ceramic filter that is connected to the audio integrated block frequency discriminator tuning loop. If no component exchange, available “electric shock method” repair. The specific method is: Use about 100V voltage on the ceramic filter poles for instantaneous power. In operation, the action should be faster, if not at all, can be repeated many times,
