康佳智能液晶电视强制升级系统失败后的维修
康佳T49U智能液晶电视出现开机画面后图像静止，大概一分钟左右后待机，强制升级无法升级系统。该机器才用msf6a648芯片，通过升级页面以及打印信息确定为EMMC故障。该EMMC为东芝4G芯片，EMMC版本为5.0。拆掉芯片上编程器发现可以识别品牌和容量，但是已经无法读取原机数据，找一个新硬盘用备份数据刷写后上机一切正常。提示，此机器主板比较脆弱，拆装EMMC需要速度比较快，不然板子有变形风险。一定要当心，因为这个板子比较贵[呲牙]https://p3-sign.toutiaoimg.com/pgc-image/954eda30a746413f9d40eeec7b5b6ded~tplv-tt-large.image?x-expires=1974466986&x-signature=Q%2FNvYttlrfB9314jVlkjXMArPDM%3D
