日本产 CQ-BT1130A 型音响主要配装于丰田面包车、丰田客货两用车等车型。该机采用电子线路控制整机的各种工作状态,收音部分具有电脑自动选台的功能,而放音部分能自动进出磁带,功能较齐全,音响效果也较好。但由于该机型一般为原车安装,其机体较重,放音部分机械结构较复杂,控制电路的自动化程度较高,一旦出现故障其维修难度较大。故障现象:收音正常,放音时推进磁带后显示屏上的数字消失,机器无任何反应。分析与检修:推进磁带后整机无反应的原因主要有:1.机内 Japan-made CQ-BT1130A-type audio is mainly equipped with Toyota vans, Toyota passenger cars and other models. The machine uses electronic circuits to control a variety of working conditions of the whole machine, the radio part of the computer automatically selects the function of Taiwan, while the playback part of the tape can be automatically out of the tape, the function is more complete, the sound is also better. However, due to the model is generally the original car installation, the heavier body, playback part of the mechanical structure is more complicated, a higher degree of automation of the control circuit, in the event of failure of its maintenance more difficult. Symptom: normal radio, audio playback tape after the disappearance of the figures on the screen, the machine without any reaction. Analysis and Overhaul: The reasons for non-reaction of the whole machine after advancing the tape include: 1. Inside the machine
