一、专用仪器检测法电视机的有些故障(如无图像)产生的原因很多,而且范围很大,此时用万用表检修就不太方便了,这就需要用专门仪器配合检修。一般是用专门仪器将故障范围缩小,再用万用表等找出具体的故障元器件。1.用图像信号发生器检查故障用图像信号发生器所产生的射频信号(RF)、中频 First, the detection of special equipment Some television failure (such as no image) for many reasons, but also a large range, this time with a multimeter maintenance is not very convenient, which requires special equipment with overhaul. General is to use specialized equipment to narrow the scope of the fault, and then find the specific multimeter and other fault components. 1. With the image signal generator to check the fault with the image signal generator RF signal (RF), intermediate frequency
