我们都经历过这些 —— 应该能修好，但事实并非如此。出了点问题。很慌张。但首先请深呼吸一下，让我们再确认一下。
检查
当你检查你的步骤时，许多问题会神奇地解决。它就在那里 “你试过关机再开机吗？” ——听上去太简单了但是很多时候就能解决问题。在进行更复杂的故障排除之前，请尝试此操作。
对于初学者，请仔细仔细检查设备的名称和型号，并确保你已收到兼容的更换配件。例如，iPhone 6与iPhone 6s或6 Plus不同，且配件不兼容。检查更换配件，确保其与你卸下的旧配件相匹配。
接下来，第二次检查维修指南步骤，仔细阅读和验证每一步。（切记关闭电源并断开电池。）当你工作时：
- 阅读评论 关于可能出错的线索。
- 重新安装”每个接口，断开连接并重新连接它以确保它连接。特别注意看起来可能与你的问题有关的任何连接。例如，如果问题是空白或毛刺，请重新安装显示器接口。
- ***仔细检查每个接口插座是否有灰尘，弯曲的针脚或其它问题。如果插座或接口看起来很脏，请用一些压缩空气将其冲洗干净。如果需要，请用异丙醇（90％或更高）仔细清洁，然后风干。****检查是否有意外损坏''' —— 仔细检查电缆和组件，确保没有任何东西被夹住或撕裂。注意任何暴露的铜线或裸线。
- 检查其它任何看起来不错的东西。是否有任何遗漏或错位的组件？你剩下零件了吗？你是否跳过任何步骤，或忽略了警告？你是否用螺丝刀或任何其他导电金属工具撬动你的设备？如果一切正常，请重新组装设备，重新连接电池，然后测试以确定问题是否已解决。
检查有缺陷的部件
如果你的设备工作得更好，即使是在旧的破裂屏幕或老电池情况下—— 或者你刚刚更换的任何组件 ——请尝试重新连接旧配件，看看是否能解决你的问题。（不要忘记在工作时断开电池。）如果你的问题清除，并且你确定你收到了特定型号的正确部件，则可能意味着你的更换部件出现问题。
如果你从iFixit购买了零件，联系客户支持，我们可以快速验证问题并尽可能为你更换任何有缺陷的零件。如果你在其他地方购买了零件，则需要与供应商进行分类。（但是，如果你想支持我们为所有内容提供免费维修指南的使命，请考虑从iFixit 购买你的下一个配件或工具。）
可悲的是，如果安装了旧配件，你的问题仍然存在。并且这是你在开始修理之前没有的问题，那么可能是在维修过程中出现问题。也许电缆被拉得太紧，或者你的撬具工具的任意插入损坏了电路板上的东西。iFixit的保修 不包括意外损坏，但我们已经创建了一些很好的资源来帮助你识别问题并找出下一步该做什么。不要放弃！
仔细检查一切是否有损坏，并拍下你发现的任何东西。通常可以通过更换附件来固定损坏的电缆。修复电路板损坏通常需要专业人员进行微观焊接帮助，但这是非常明确的。

I replaced the battery in my Series 1 and now it won't turn on at all. I followed and rechecked all the steps. After disassembly the connector wouldn't fit snug to the new battery connector no matter how I tried. I have to assume that is the issue. Eventually I tried using some adhesive to hold the 2 connectors together and though they appeared to stay in place after that still nothing. :-(

Samsung galaxy note ten. Dodgy guy replaced cracked screen and now it’s not reconnected and coming away at both sides, battery might of been hurt in a way during fixing and just wanna know if he has to fix this after I paid him to put a glass screen protector on and he put a dodgy plastic one on there and then I called him on it and he promised me that it was just as good as the glass versions. It’s not. It smashed so I took it back in and said lifetime guarantee and he took to fix. Now I got it back and I feel like I’m he sides are not glued or connected properly so he’s made me clamp it all night
What do ido
