该机采用三洋LA7680机心电路,微处理器为CH04001-5CZS(D701)。为了进一步取得验证,采用人为解除“蓝屏”现象的方法;将LA7680“#!脚(同步分离信号输入端)外接“蓝屏”控制中路中的C312暂时断开,然后再利用“微调节目”键,微调出图像质量良好,但仍然无伴音,控制CPU%$脚(音量控制
The machine uses Sanyo LA7680 movement circuit, microprocessor CH04001-5CZS (D701). In order to further verify, the man-made way to lift the ”blue screen“ phenomenon; the LA7680 ”#! Feet (sync separate signal input) external“ blue screen ”control in the middle of the C312 temporarily disconnect, and then use the“ Fine tune program ”button , Fine-tune the image quality is good, but still no sound, control CPU% $ feet (volume control
