海爾滾筒故障代碼err7(海爾滾筒故障代碼Err7)

前沿拓展：

?故障現(xiàn)象：開機打印信息顯示待機，開啟后電視可以開機，灰屏沒反應，用修機王顯示一樣。

打印信息如下:

Hello PM51...

Enter STR

MDrv_PM_PowerDown2Standby

一看信息好了待機，開機抓打印看一下，開機后，沒有任何打印信息，難道串口關閉，isp自動識別可以識別到并且可以讀出引導程序，暗喜帶25c16，遂將引導程序用HXD十六進制編程器打開一看果然串口關閉。

馬上用16進制將串口打開，打印信息出來了但是不能開機了，也不能灰屏了。

打印如下：

其實心中已經(jīng)知道emmc已經(jīng)危險了，但心中還是沒托底，馬上找羅老師問一下，建議我更換emmc，心中疑惑為啥改個串口，怎么還不能像原來不能灰屏了，詢問老師，老師道趕緊換，教條啥，哎沒辦法，趕緊換吧。

馬上更換emmc，進控制臺uup升級，問題解決。

此問題在大師眼里就是小活，但對于新手來說，還是有很多知識點，借此拋磚引玉，希望可以幫助同行兄弟。
