(一)彩电升级是一个很大范围的问题:比如大多数过去的老式彩电增加电脑板,变成微处理器遥控选台;原来是微处理器选台的电视机(比如日立2025/2125)不带遥控,需要更换CPU板,使之遥控化;随着影碟机(如:VCD)普遍进入家庭,需要把原有的无AV输入端子的遥控彩电增加AV输入端子(或者多个端子);非CATV彩电更换增补高频头,使之可以接收增补频段的节目;更有甚者,刚买了不几年的大屏幕I~2C彩电(如长虹2919/P/PS、2939KS、C3418PS等)却需要更换I~2C增补高频头(厂家要求用ENV598E6GC更
(A) color TV upgrade is a very wide range of issues: For example, most of the past, the increase in the old color TV board, into a microprocessor remote control channel selection; the original is the microprocessor TV channel selection (such as Hitachi 2025/2125) Without remote control, you need to replace the CPU board so that it can be remotely controlled. As the DVD player (such as VCD) generally enters the home, you need to add the AV input terminal (or multiple terminals) to the original remote color TV with no AV input terminal. Non-CATV color TV to replace the tuner, so that it can receive additional band programs; what is more, just bought a few years of large screen I ~ 2C color TV (such as Changhong 2919 / P / PS, 2939KS, C3418PS, etc.) But need to replace I ~ 2C additional tuner (manufacturers require ENV598E6GC more
