成都牌C53—871彩电采用的是三洋83P机芯。按通常方法,如该机行输出变压器损坏可以用83P机芯行输出变压器直接代换。但是我们在维修中发现,如直接代换该机会发生无声音、无字符显示和所有模拟量控制都失效的现象,此时维修者往往误以为是遥控电路发生了故障,使维修工作走入弯路。我在修理此种故障时经检查发现,主要原因是成都牌C53—871平面直角遥控彩电行输出变压器第⑧ Chengdu C53-871 color TV using Sanyo 83P movement. According to the usual method, such as the machine output transformer damage can be used 83P core output transformer direct substitution. However, we found in the maintenance, such as the direct substitution of the opportunity to have no sound, no character display and all the analog control is invalid phenomenon, the maintenance often mistakenly believe that the remote control circuit has failed, the maintenance work into the detours . When I repair this failure, the inspection found that the main reason is the Chengdu brand C53-871 flat-panel remote color TV line output transformer ⑧
