1998年以后生产的 VCD 机大都采用 CL680解码板,该解码板具有卡拉 OK 原唱消除、N/P制式自动转换、九画面浏览、画面16倍放大、2倍速度快放、1/8倍速度慢放、8级变调、8种声、场模式选择等诸多功能。应用 CL680解码板的 VCD机型主要有长虹红太阳 VD6000、红太阳VD9000、厦新 VCD—777、VCD—768、VCD—786、万利达 VCP—N30、爱多 IV—308BK、步步高AB—0072、步步高 AB001等机型。目前,采用CL680解码板的 VCD 己经进入了维修期,由于目前关于该芯片的维修资料较少,在此,本文以厦新VCD—777机为例介绍 CL680解码板的工作过程及维修方法,供同行参考。
VCD machines produced after 1998 mostly use the CL680 decoder board, the decoder board has Kara OK OK original elimination, N / P format automatic conversion, nine screen browsing, 16 times magnification of the screen, 2 times faster, 1/8 times faster Slow release, 8 level tone, 8 kinds of sound, field mode selection and many other features. Application CL680 decoder board VCD models are Changhong red sun VD6000, red sun VD9000, Xiamen new VCD-777, VCD-768, VCD-786, Malata VCP-N30, love more IV-308BK, AB-0072 backgammon, backgammon AB001 Other models. At present, the VCD using the CL680 decoder board has entered the maintenance period, due to the current maintenance of the chip less information, in this paper, Xiamen new VCD-777 machine as an example to introduce CL680 decoder board working process and maintenance methods for Peer reference.
