海信5060主板死机

在，有些主板就测不了，尤其是上平信号不是LVDS的

如果上屏信号不是LVDS的，有相应的信号转换器吗？

硬件已搞定，就差刷机包

1363822353

总算把指示灯搞亮了

1363822353

历尽艰难险阻，主芯片拆焊四次，emmc拆焊八次，从原来的指示灯不开机搞到这个样子了，u盘升级还是不成功，升到一半就死机

大功告成，谢谢论坛各位师傅的帮助。

是EMMC坏了吗？

是EMMC的问题吗？

就是这个东东坏了，途中走了很多弯路，现在修好了来总结一下经验，一是海信5060主板的VGA串口看不到打印信息，809H也看不到此板的打印信息，这就误导了我多次买和拆焊主芯片

看打印只能用串口打印软件
