红、绿、蓝;红外线

试题分析:自然界的其他颜色的光可以由红、绿、蓝三种颜色的光混合而成,所以制造电视机时,其画面颜色是由红、绿、蓝三种色条合成;各种用电器的遥控器均用红外线来遥控,所以电视机遥控器用红外线来遥控。

电视机屏幕颜色

机器被磁化了.这是彩电的最常见故障.
故障部位在消磁,重点是消磁电阻.
29的电视,因区域\维修者追求的利润不同,维修费为15–30元.如你自己能更换,买个消磁电阻大概5元.

电视显示屏问题

显示屏上下变窄是“场振荡电路”的问题,这个零件便宜五块至十块的本钱就够了,至于工钱你们那看是什标准!如果是左右变窄那是“行振荡电路”的问题这个处理方式是一样的! 是上下变窄。还是左右啊?上下变窄的是场扫描出了问题。不然的话问题出在行扫描。如果安成本价来修的话。几块大洋的事情。如果拿到修理的地方去修,那就得几十块了。功夫费+技术费+成本费=维修费 应说明是上下变窄还是左右变窄,上下变窄是几块钱的事,左右变窄可就不是几块钱的事了!应该说明白,大家好帮你. 场输出反馈元件热稳定性变差造成的
