接手一台长虹LED32C1000N开机出现LOGO后循环重启。此板带有miniLVDS屏信号接口,屏型号是京东方C320X14-E4-B,检查硬件电路并没有什么异常,怀疑是引导或程序问题。注意:升级之前请认准板号,不要弄错。

关于如何串口连接不用多说。打开secureCRT,给主板上电。从打印信息可以看出大概意思是:程序文件存在坏块,找不到xx文件,初始化失败等等。并且串口打印默认是关闭的,不能进入控制台,看来只有重新刷写引导,再用USB强制升级。

连接串口,按照下面的步骤升级。注意:第四步连接不上可以多试几下,或者重新给主板上电再点连接

引导烧录好,就剩最后一步了,---USB强制升级。。。

把USB强制升级文件复制到优盘根目录,提前插入TV主板USB口。

连接securCRT串口打印,按enter键不放给主板上电,出现 nikion#命令符再松开,就可以进入控制台了。输入cu或usb start,之后会自动识别升级文件,直到电视出现正常画面为止,此过程需要几分钟。
工厂模式进入方法是:信号源-0-8-1-6,退出:遥控关机
