有维修经验的朋友请指点一二啊！谢了！

持续蓝闪，没有任何画面信号。

国外技术人员的看法（综合了NV显卡门、360死亡三红、PS4死亡蓝闪）

Welcome to the world of modern electronics   I'm an electronics repairer and see issues like this all the time. Issues with modern surface mount tech aren't going away while the RoHS crap is still in force, and guys like me are forced to use lead free solder. 2006 was the year of doom for electronics, as things get smaller, the solder joints get smaller and more failure prone, especially with chip technology like BGA. Soft solder and tiny joints are a recipe for disaster.The RoHS guys will tell you that lead-free solder has higher melting temperatures, it's a load of rubbish, it's softer than lead solder even cold on the reel before it's used, the solder in BGA array balls shift in the middle of the temperature range caused by the pressure of the cooler. It caused nVidia failures, Xbox360 RRoD's, and the PS3 issues. The Xbone and PS4 *might* still have these issues down the line...The bent pins issue in HDMI sockets proves just how cheap connectors are these days. SATA and HDMI are prime examples, look at how solid SCART sockets used to be.....

在各个论坛了解了一些成功修复的机器，除了少量发现属于电源问题，几乎都是重做BGA后得到修复，还有的甚至被维修人员告知APU/RAM/ROM全部出现BGA封装缺陷。不能修复的机器则被告知是处理器或其他芯片损坏。

希望有了解详情、掌握第一手资料的兄弟进来分享一下维修经验。

直接换，基本没法修。

我在一个PS4蓝灯群里看到一部分用户通过BGA修复成功了，但是联系到当年3红的情况，修好估计也坚持不了太长时日，并且目前的PS4很可能存在普遍的结构性缺陷，全面爆发只是时间问题。
