我的指示灯也是通过主芯片控制的。我的估计是主芯片坏了。主芯片是BGA的，有点难搞。各电压测量点都正常 ...

你接串口.电脑显示什么. 东西 .我估计也是主芯片也坏了.因为只有BOO显示.

极速之光C

刚遇到一台，换了EMMC之后，写入引导之后开机打印信息都没有了，怀疑BGA主芯片有问题

这段时间这台电视可把我忙坏了.这是原贴

之前大家回贴说是程序坏了在淘宝花了十五元钱买了引导和主程序根本就刷不进去


之后又花了钱在淘宝买了一块装上去不行.

【新提醒】没有办法今天终于把液晶LED40H150J解决好了_液晶电视维修_家电维修论坛 - www.jdwx.info

没有想到买来的主板装上去显示湖南有线在本地江西根本上就用不上.搜不到台显示搜台失败,花了十一元钱又寄回去了.

没有办法后来在一个网上也看到同样故障的帖子也是显示BOO不过那个贴子不是海信的好像是康佳的.那个高手换了主芯片就好了.我也在淘宝又定了MT5505BKDI这不今天到了货.中午吃完饭就开始吹上去了.









一开始吹的时候风有点大把芯片吹边了吓的我猪逼丝一样.不过还好又吹回去了.没有想到接上电源打印信息都没有了.后来又把风枪温度开到大一点风量大一点.放心的吹了.因为这个时候芯片不会动了.可以大一点了.然后再接上电源,
激动人心的时候终于出现了.打印终于不再显示BOO了.显示这个了大家看看.

看到这么多打印我胆小的心情那是多么的高兴呀.终于不再显示BOO了.注意此时我是接上十二伏电源其它没有接的时候连接电脑的.之后我正式的装在电视上.当我打开电源开关的时候发现面板显示灯只亮了一下白灯.就没有反应了.这下完了.怎么回事.本来准备再拆下来再用风枪再吹一遍的时候发现这个电视的右边的指示灯亮了红色灯.我心想会不会是待机了.果然用摇控器开机.终于出现了久为已久的开机画面和开机声音.另付上接上电视的打印信息.

一开始大家都没有想到是主芯片坏了.现在换了主芯片试机一下午正常.
想想走了这么多弯路真是不容易呀.

上传了三张买来的新芯片的图片.和吹下芯片来的主板图片.其它焊接的图片因为紧张没有拍一个人也不好拍.搞这个有什么好吹的是吧.好了就是好了是吧.

BGA都能搞，是用什么设备

得过且过O32152

真的佩服楼主  技术不错
