真心后悔没有换购809H,待我说下原因,前些日接到一台长虹43D2000N机芯ZLS53i2存储器型号GD5F1GQ4U开机就重启,由于修过这个机器,刷机就正常了,对用户报了价,然后把用户打发走了,开始在本论坛里找数据,还真有,窃喜中,结果,插上U盘无法升级,这下傻眼了,上打印信息一看,

完了!
Bad block table found at page 65216, version 0x01打印信息显示FLASH有坏块,这就没办法了,换板吧,已对用户报过价,修吧,FLASH不好搞呀,最后在论坛里又找了相关贴子,发现可以换存储器,在这里感谢备份数据的师傅们,感谢小罗-强辉电子师傅,感谢他的本存储器的烧写方法,然后购得几块存储器,将存储器焊下,拿块新的夹在存储器夹子上,将编程器软件更新至最新,点识别,果然识别出来,然后导入数据,写入成功,新程序装机,试机果然不再重启,心中兴奋,调整屏参后机器正常,交于用户!至此本机维修结束,感谢季总的神器,然后再回过头想到几年来修的多台升不了级的主板,如果能整机写入数据,或者写入引导的话,肯定能救活,这才感到了809H的重要性,想换购一台,才发现活动已经结束了,后悔呀,不是不舍得钱,而是发的全新的809F还有好几台,我这肯定没季总那好卖,所以想问一下季总,809H的换购以后还会不会有了,要是有的话我就等,拿全新的换一台,要是没了请季总给个话,发工资了直接买一台,神器必需得有!下面是修理本机的过程,及用到的数据,等等文件,全部打包,本次下载不收金币,感谢广大网友!
