(Apple TV)插入电源插座时，Apple TV会自动开启。状态灯缓慢闪烁，并在您打开流媒体设备时保持亮起。如果您的Apple TV(Apple TV)在接通电源后无法开机，请遵循本文中的四项建议。
如果您使用损坏或伪造的电源线，或者电源插座有问题，则流媒体设备将不会启动。由于固件损坏和制造缺陷，您的Apple TV 也可能无法打开。
注意：(Note:)本指南中的故障排除步骤适用于所有Apple TV 型号和世代(Apple TV models and generations)。
1.强制重启Apple TV
您的Apple TV 会在几分钟不活动后进入睡眠状态。通常，按遥控器上的电源(Power)、菜单(Menu)或电视按钮应该唤醒设备。如果您的Apple TV 没有唤醒，它可能处于睡眠模式。
在这种情况下，请尝试使用Apple TV Remote强制重启设备。然后，将Apple TV 插入电源插座并按照以下说明进行操作。
如果您有Siri Remote（第 2 代），请同时按住返回(Back)和TV/Control Center按钮，直到Apple TV 上的状态指示灯闪烁。
在第一代Siri Remote上，按住Menu和TV/Control按钮直到状态灯闪烁将重新启动Apple TV。
要使用铝制或白色Apple Remote强制重启Apple TV，请按住菜单(Menu)和向下(Down)按钮，并在状态指示灯闪烁时松开。
如果您的Apple TV 仍然没有打开或没有响应这些命令，则很可能是没有正确连接到电源。
2. 检查你的电源插座
确认您的电源插座工作正常。从墙上插座拔下Apple TV电源线，稍等片刻，然后重新插入。如果电源线连接松动，机顶盒将无法打开。因此，请确保电源线的两端都紧紧插入Apple TV和电源插座。
如果您的Apple TV 仍然无法开机，请拔下电源线，然后将其他设备插入同一个插座。
如果插座为其他设备供电，则Apple TV 的电源线或电源端口很可能已损坏。请联系Apple TV 支持(Apple TV Support)或前往Genius Bar 天才吧(Genius Bar)寻求专业帮助。
3.使用原装(Use Original)或正品(Authentic)配件
确保(Make)您使用的是Apple TV随附的专用电源线。所有Apple TV型号均配备一台开箱即用。但是，假冒电缆或为其他设备量身定制的电缆可能无法为您的Apple TV供电，因此最好使用(Apple TV)Apple专为机顶盒设计的电缆。
如果您放错了原装电源线，请前往Apple 官方配件商店购买与您的(Apple’s official accessories store)Apple TV 型号兼容的替换电源线。如果您怀疑Apple TV 线缆已损坏，请使用该线缆为另一台 Apple(Apple) TV 供电，并在购买替换线缆之前检查它是否正常工作。
如果电缆在其他Apple TV(Apple TVs)上正常工作，则无法打开的Apple TV 可能是电源端口出现故障。(Apple)请联系Apple TV 支持(Apple TV Support)或前往附近的Genius Bar 天才吧(Genius Bar)进行修复。
4. 重置您的 Apple TV
tvOS 更新期间的停电或中断可能会破坏Apple TV 的固件或使设备变砖。如果您在安装更新时拔掉了流媒体设备，这可能是您的Apple TV 无法打开的原因。我们的 Apple TV 更新指南(guide on updating Apple TV)提供了一些有用的 tvOS 故障排除提示。
如果问题是由于固件损坏造成的，请将Apple TV 重置为出厂默认设置。由于Apple TV 未打开，因此使用Mac或 PC 执行硬重置是唯一可行的选择。您只需要一根USB数据线和一台具有高速互联网连接的计算机。
注意：(Note:)只有带有USB端口的 Apple TV型号（ (Apple TV)Apple TV 4K（第 1 代）到第 1 代Apple TV）才能(Apple TV—can)使用电脑重置为出厂默认设置。
请访问授权的 Apple 服务提供商(authorized Apple Service Provider)以重置不带USB端口的Apple TV 。(Apple TVs)您会在Apple TV背面找到端口（ USB-C或微型USB ）。此Apple 支持文档还包含带有(Apple Support document)USB端口和其他连接器的Apple TV型号的图示。
- 从Apple(Apple) TV 上拔下所有线缆（电源线和HDMI线缆），然后使用合适的USB线缆将其连接到Mac或 PC 。
- 启动Finder（在Mac上）并在边栏中选择您的Apple TV。在Windows上，启动iTunes并选择“音乐”下拉菜单旁边的Apple TV 徽标。(Apple TV logo)
- 连接到电脑后，Apple TV会自动进入恢复模式(Recovery Mode)。选择恢复(Restore)（或恢复 Apple TV(Restore Apple TV)）并等待Finder或 iTunes 下载必要的文件以重置Apple TV。
如果您的电脑未检测到您的Apple TV，请断开设备并将其重新插入电脑。或者，尝试使用另一根USB电缆。对于Windows，请确保您使用的是最新版本的 iTunes。前往Microsoft Store更新应用程序或从Apple 网站( Apple’s website)下载最新的 iTunes 。
根据您的网速和Apple TV型号，恢复过程可能需要几分钟时间。如果成功，您将收到一条消息“您的Apple TV已恢复到出厂设置。”从电脑上拔下 Apple TV，连接电源线和HDMI线(” Unplug)，(Apple TV)然后(HDMI)等待它开机。
硬件损坏是可能的
制造缺陷几乎不可能靠自己修复。如果您在生产过程中没有正确组装Apple TV，或者在运输过程中损坏了，它可能会在一段时间后无法启动或停止工作。因此，如果这些建议都不能恢复您的Apple TV，请联系卖家报告问题或要求更换。
Apple TV Not Turning On? Try These 4 Fixes
Apple TV automatically comes on when plugged into а рower outlet. The status light flashes slowly, and it stays on whеn you switch on the streaming device. Follow the four recommendations in thіѕ article if your Apple TV is not turning on when plugged into power.
The streaming device won’t come on if you’re using a damaged or counterfeit power cable or if there’s a problem with the power outlet. Your Apple TV may also fail to turn on due to firmware corruption and manufacturing defects.
Note: The troubleshooting steps in this guide apply to all Apple TV models and generations.
1. Force Restart the Apple TV
Your Apple TV will go to sleep after minutes of inactivity. Usually, pressing the Power, Menu, or TV button on the remote should wake the device. If your Apple TV doesn’t wake, it’s probably stuck in sleep mode.
In that case, try force restarting the device using your Apple TV Remote. Then, keep the Apple TV plugged into a power outlet and follow the instructions below.
If you have the Siri Remote (2nd generation), hold down the Back and TV/Control Center buttons simultaneously until the status light on the Apple TV flashes.
On the 1st generation Siri Remote, holding down the Menu and TV/Control buttons until the status light flashes will restart the Apple TV.
To force restart your Apple TV with aluminum or white Apple Remote, press and hold the Menu and Down buttons and let go when the status light flashes.
If your Apple TV still is not turning on or doesn’t respond to these commands, it most likely isn’t properly connected to a power source.
2. Check Your Power Outlet
Verify that your power outlet is working correctly. Unplug the Apple TV power cable from the wall socket, wait for a minute, and plug it back in. The set-top box won’t turn on if the power cable connection is loose. So, make sure both ends of the power cable are tightly plugged into the Apple TV and power outlet.
If your Apple TV still won’t come on, unplug the power cable, and plug a different device into the same outlet.
If the outlet powers other devices, your Apple TV’s power cable or power port is most likely broken. Contact Apple TV Support or visit a Genius Bar for professional assistance.
3. Use Original or Authentic Accessories
Make sure you’re using the dedicated power cable that shipped with your Apple TV. All Apple TV models come with one out-of-the-box. However, counterfeit cables or cables tailored for other appliances might not power your Apple TV, so it’s best to use the cable specifically designed for the set-top box by Apple.
If you misplaced the original power cable, head to Apple’s official accessories store to purchase a replacement cable that’s compatible with your Apple TV model. If you suspect that your Apple TV cable is damaged, use the cable to power another Apple TV and check if it works before buying a replacement cable.
If the cable works on other Apple TVs, the Apple TV that won’t turn on probably has a faulty power port. Contact Apple TV Support or visit a nearby Genius Bar to have it fixed.
4. Reset Your Apple TV
Power outages or interruptions during a tvOS update can mess up Apple TV’s firmware or brick the device. If you unplugged the streaming device while installing an update, that could be the reason why your Apple TV won’t turn on. Our guide on updating Apple TV has some useful tvOS troubleshooting tips.
If the problem is due to firmware corruption, reset your Apple TV to factory default. Since the Apple TV is not turning on, performing a hard reset using a Mac or PC is the only viable option. All you need is a USB cable and a computer with a high-speed internet connection.
Note: Only Apple TV models with a USB port—Apple TV 4K (1st generation) down to the 1st generation Apple TV—can be reset to factory default using a computer.
Visit an authorized Apple Service Provider to reset Apple TVs without USB ports. You’ll find the ports (USB-C or micro USB) on the back of your Apple TV. This Apple Support document also has pictorial representations of Apple TV models with USB ports and other connectors.
- Unplug all cables (power and HDMI cables) from your Apple TV and connect it to your Mac or PC using the appropriate USB cable.
- Launch Finder (on Mac) and select your Apple TV in the sidebar. On Windows, launch iTunes and select the Apple TV logo next to the “Music” drop-down menu.
- When connected to a computer, Apple TV automatically enters Recovery Mode. Select Restore (or Restore Apple TV) and wait for Finder or iTunes to download the necessary files to reset the Apple TV.
If your computer doesn’t detect your Apple TV, disconnect the device and plug it back into your computer. Or, try using another USB cable. For Windows, make sure you’re using the latest version of iTunes. Head to the Microsoft Store to update the app or download the latest iTunes from Apple’s website.
Depending on your internet speed and the Apple TV model, the restoration process might take a couple of minutes. If successful, you’ll get a message that “your Apple TV has been restored to factory settings.” Unplug the Apple TV from your computer, connect the power and HDMI cables, and wait for it to come on.
Hardware Damage Is a Possibility
Manufacturing defects are almost impossible to fix on your own. If you didn’t correctly assemble your Apple TV during production, or it got damaged during shipping, it may not come on or stop working after some time. So, if none of these recommendations revive your Apple TV, contact the seller to report the problem or request a replacement.
