不幸的是，如果您正在阅读此页面，您的 Playstation 4 系统可能会遇到一些问题。与任何新硬件一样，总会有一些问题需要解决。幸运的是，PS4有一个内置的安全模式选项，可让您尝试修复您的系统。
有趣的是，索尼(Sony)在PS4中设置了安全模式选项，但微软在(Microsoft)Xbox(Xbox one)上没有类似的选项，尽管每个人都知道Windows的安全模式。您可以在低分辨率模式下启动Xbox One ，但仅此而已。(Xbox one)没有用于解决问题的专用诊断模式。
将 PS4 引导至安全模式
要将您的PS4启动到安全模式，只需按照以下步骤操作：
1. 按下前面的电源按钮关闭 PS4。它可能需要几秒钟才能完全关闭。
2. 现在再次按下电源按钮，但这次按住不放。第一次按下时您会听到一声哔声，大约七秒后您会听到第二次哔声。听到第二声哔声后，您可以松开电源按钮。
3. 启动后，使用提供的USB电缆将DualShock控制器连接到系统，然后按下PS按钮。它不会无线连接，所以你需要去找那根电缆，希望它还在盒子里。
如果您正确执行了所有操作，此时应该会弹出安全模式屏幕，并且您应该看到以下选项：
让我们通过不同的选项来了解它们的作用以及系统上的哪些数据受到影响。
1.重新启动 PS4(Restart the PS4) – 就像重新启动计算机一样，这将在正常模式下重新启动PS4 。关闭你的PS4并重新打开它与重新启动是一样的，所以如果这不能解决你的问题，让我们向下移动。
2.更改分辨率(Change Resolution)- 如果您将PS4连接到不支持高分辨率的旧显示器并且最终出现空白或黑屏，这将非常有用。选择此选项将以 480p 分辨率重新启动PS4。
3.更新系统软件(Update System Software)– 您可以使用此选项通过Internet、USB或光盘更新PS4软件。
4.恢复默认设置(Restore Default Settings)——这会将Playstation 4重置为出厂默认设置。根据索尼(Sony)网站的说法，这个选项似乎不会删除您的用户数据，而只是将设置重置为默认值。这包括日期和时间、网络设置、视频/显示设置、音频设置、视频播放设置等。它不会降级系统固件。
5.重建数据库(Rebuild Database)——这将删除当前数据库，创建一个新数据库并扫描系统上的所有内容。如果数据库已损坏，这应该可以解决问题
6.初始化 PS4——(Initialize PS4)这最后两个选项几乎可以将你的PS4重新设置为一个干净的状态。此选项将删除系统固件以外的所有内容。这意味着您可以重新打开它，它将以全新的方式启动。
7. Initialize PS4 (Reinstall System Software) – 该选项同6，但也会删除系统软件。您基本上是从空白硬盘开始的。如果您想用更快或更大的硬盘替换 PS4 硬盘，则此选项非常有用。(replace the PS4 hard drive)默认情况下，它是 500GB 7400 RPM驱动器。放入新驱动器后，您将使用此选项并将系统软件从您的计算机下载到U盘上。(USB)插入它，它将重新安装系统固件。
PS4的其他问题可能表明实际硬件存在问题。例如，许多PS4(PS4)用户看到的闪烁蓝灯和闪烁红灯问题。这两个也是导致PS4意外关机或关机的罪魁祸首。
PS4 蓝光闪烁疑难解答(Troubleshoot PS4 Blinking Blue Light)
如果您的PS4无法正常开机或随机关闭并且卡在闪烁的蓝光而不是变成白色的状态下，那么您的硬件可能存在问题。您可以尝试以下几件事：
1.检查电源适配器和PS4(PS4)背面的电源接口。确保(Make)没有明显损坏或弯曲。您甚至可以在PS4上使用(PS4)PS3的电源线。
2. 导致蓝光问题的第二个问题是硬盘驱动器托架未正确连接或松动。您应该关闭控制台，拔下所有电缆，然后按照箭头指向的方向滑出HDD托架盖。(HDD)
显然有一个螺丝将整个东西固定下来，所以如果它松动，那么硬盘驱动器可能没有正确连接。您可以卸下该螺钉并取出硬盘(HDD)并将其放回原处。
3. 最后，可能是HDMI输出端口的问题或电视兼容性问题。拔下HDMI线，确保PS4上的端口没有损坏。如果可能，请尝试使用不同的HDMI电缆。您还应该尝试将系统连接到另一台电视，看看是否能解决问题。

PS4 红灯闪烁
如果您收到闪烁的红灯而不是正常的白灯，则表明PS4过热。系统没有获得足够的气流，或者当前位置太热。如果系统碰巧塞在某物内，请尝试将系统移至更开放的空间。
您可以尝试的另一件事是将其直立而不是平放。似乎Xbox One解决了他们在 Xbox 360 上遇到的这个臭名昭著的问题，但它还没有在PS4上根除。
PS4 软件更新问题
如果您尝试更新您的PS4系统软件并且出现问题，那么您唯一的选择就是擦除所有内容并从头开始。如果您安装了更新，但重新启动PS4并提示您重新安装相同的更新，就像第一次从未安装过一样，您将不得不重新初始化PS4。
您可以通过进入安全模式，选择选项 4，然后在控制台重新启动时，选择选项 6 来做到这一点。您必须重新设置它。
PS4 音频问题
PS4最突出的问题之一与音频输出有关。PS4可以输出数字或光学格式的音频。默认情况下，它会根据连接自动检测和优化音频。如果您连接了HDMI电缆，音频将通过HDMI发送。当您的设置复杂或系统不支持某种类型的音频时，就会出现问题。(Problems)
第一个问题是，如果您将PS4(PS4)连接到使用不支持HDCP（高带宽数字内容保护(High-bandwidth Digital Content Protection)）的HDMI的设备，您将听不到任何声音。实际上，如果它不支持，您将无法获得音频或视频，因此如果您通过接收器，请尝试连接到另一台设备或直接连接到您的电视。
其次，您可能需要更改音频输出设置。转到声音和屏幕(Sound and Screen)，然后转到音频输出设置(Audio Output Settings)。
在这里，确保输出(Output)到耳机(Headphones)是灰色的，并尝试在数字输出(Digital Out)（光纤(Optical)）和HDMI之间更改主输出端口(Primary Output Port)。如果您有音频分配器并且您的中置声道没有输出任何音频，您应该将输出设置为Digital Out (Optical)，取消选中DDS5.1、ACC和DTS5.1，然后选中Audio Format 下的Linear PCM 。
现在，当您播放支持DTS5.1或DDS 5.1的电影时，它只会检测线性 PCM(Linear PCM)立体声输出。要解决该问题，您必须在播放光盘时按选项(Options)，转到设置(Settings)并选择音频格式( Audio Format)下的比特流（直接）(Bitstream (Direct))。
PS4 控制台冻结
如果你的PS4主机经常死机，你可以做一些事情。首先，您应该尽快从Playstation Network下载系统软件的任何更新。
如果您在尝试自行下载更新时遇到冻结，那么您应该直接从Sony网站下载它们，将它们复制到USB驱动器，然后通过将(USB)USB驱动器连接到您的控制台直接安装它们。这是一个有点乏味的过程，但希望当您运行最新版本的系统软件时，您不必再次手动执行此操作。

Ultimate Guide to Troubleshooting PS4
Unfortunately, if you’re reading this page, you’re probably haνing some trouble wіth your Playstatіon 4 system. As with any new hardware, there are always kinks to be worked out. Luckily, the PS4 has a built-in safe modе option that lеts you try and fix your system.
What’s funny is the fact that Sony put a safe mode option in the PS4, but Microsoft does not have a comparable option for the Xbox one, even though everyone knows about safe mode from Windows. You can boot the Xbox one in a low resolution mode, but that’s about it. There is no dedicated diagnostic mode for fixing problems.
Booting the PS4 into Safe Mode
To boot your PS4 into safe mode, just follow the steps below:
1. Turn off your PS4 by pressing the power button on the front. It might take a few seconds before it turns off completely.
2. Now press the power button again, but hold it down this time. You’ll hear one beep on the initial press and you’ll hear a second beep about seven seconds later. You can release the power button after you hear the second beep.
3. Once it boots up, connect your DualShock controller to the system using the provided USB cable and press the PS button. It won’t connect wirelessly, so you’ll need to go find that cable, which is hopefully still sitting in the box.
The safe mode screen should pop up at this point if you did everything correctly and you should see the following options:
Let’s go through the different options to see what they do and what data on your system gets affected.
1. Restart the PS4 – Like restarting your computer, this will restart the PS4 in normal mode. Turning off your PS4 and turning it back on is the same thing as restarting, so if that didn’t fix your problem, let’s move down.
2. Change Resolution – This is useful if you connected your PS4 to an older monitor that doesn’t support high resolutions and you end up with a blank or black screen. Choosing this option will restart the PS4 in 480p resolution.
3. Update System Software – You can use this option to update the PS4 software via Internet, USB or disc.
4. Restore Default Settings – This will reset the Playstation 4 to factory default settings. According to the Sony website, it seems like this option will not delete your user data, but just reset the settings to their defaults. This includes the date and time, network settings, video/display settings, audio settings, video playback settings, etc. It will not downgrade the system firmware.
5. Rebuild Database – This will delete the current database, create a new database and scan all of the content on the system. If the database has become corrupt, this should fix the problem
6. Initialize PS4 – These last two options will pretty much reset your PS4 back to a clean slate. This option will delete everything except the system firmware. This means you can turn it back on and it’ll start up brand new.
7. Initialize PS4 (Reinstall System Software) – This option is the same as 6, but will delete the system software too. You’re basically starting with a blank hard disk. This option is really use if you want to replace the PS4 hard drive with a faster or bigger one. By default, it’s a 500GB 7400 RPM drive. After you put in the new drive, you would use this option and download the system software onto a USB stick from your computer. Plug that in and it’ll reinstall the system firmware.
Other problems with your PS4 might indicate problems with the actual hardware. For example, the blinking blue light and blinking red light issues seen by many PS4 users. These two are also the major culprits behind the PS4 shutting down or turning off unexpectedly.
Troubleshoot PS4 Blinking Blue Light
If your PS4 is not powering on correctly or turns off randomly and gets stuck with a blinking blue light instead of turning white, then you could have a problem with a piece of hardware. Here are a couple of things you can try:
1. Check the power adapter and the power port on the back of the PS4. Make sure nothing is visibly damaged or bent. You can even use a power cord from the PS3 on the PS4.
2. The second issue that can cause the blue light problem is if the hard drive bay is not connected properly or has become loose. You should turn off the console, detach any cables and then slide the HDD bay cover out in the direction the arrow is pointing.
There is apparently one screw that holds the whole thing down, so if that’s loose, then the hard drive may not be connected properly. You can remove that screw and take out the HDD and put it back in.
3. Lastly, it could be an issue with the HDMI out port or a TV compatibility issue. Remove the HDMI cable and make sure there is no damage to the port on the PS4. Try a different HDMI cable, if possible. You should also try connecting the system to another TV to see if that solves the problem.

PS4 Blinking Red Light
If you’re getting a blinking red light instead of the normal white light, this indicates the PS4 is overheating. The system is not getting enough airflow or it’s simply too hot in the current location. Try moving the system to a more open space if it happens to be stuffed inside something.
Another thing you can try is to stand it upright rather than laying it flat. Seems like the Xbox One fixed this infamous problem they had on the Xbox 360, but it’s not eradicated on the PS4 just yet.
PS4 Software Update Problems
If you try to update your PS4 system software and something goes wrong, pretty much your only option is to erase everything and start from scratch. If you installed an update, but restart the PS4 and are prompted to reinstall the same update like it never got installed the first time, you’ll have to reinitialize the PS4.
You can do that by going into safe mode, choosing option 4 and then when the console restarts, choosing option 6. You’ll have to set it up all over again.
PS4 Audio Problems
One of the more prominent problems with the PS4 has to do with audio output. The PS4 can output audio in digital or optical format. By default, it’ll automatically detect and optimize the audio based on the connections. If you have an HDMI cable connected, audio will be sent over HDMI. Problems start to occur when you have a complex setup or a system that doesn’t support a certain type of audio.
The first issue is that you won’t get any sound if you connect your PS4 to a device using HDMI that doesn’t support HDCP (High-bandwidth Digital Content Protection). Actually, if it doesn’t support that, you won’t get audio or video, so try connecting to another device or directly to your TV if you’re going through a receiver.
Secondly, you might need to change the audio output settings. Go to Sound and Screen and then Audio Output Settings.
Here, make sure Output to Headphones is greyed out and try changing the Primary Output Port between Digital Out (Optical) and HDMI. If you have an audio splitter and your center channel is not outputting any audio, you should set the output to Digital Out (Optical), uncheck DDS5.1, ACC, and DTS5.1 and then check Linear PCM under Audio Format.
Now when you are playing a movie that supports DTS5.1 or DDS 5.1, it will only detect Linear PCM stereo output. To fix that problem, you have to press Options when the disc is playing, go to Settings and chose Bitstream (Direct) under Audio Format.
PS4 Console Freezing
If your PS4 console freezes a lot, there are a few things you can do. Firstly, you should download any update to the system software as soon as possible from the Playstation Network.
If you’re experiencing the freezes when trying to download the updates themselves, then you should download them directly from the Sony website, copy them to a USB drive and install them directly by connecting the USB drive to your console. It’s a bit of a tedious process, but hopefully when you are running the latest version of the system software, you won’t have to manually do it again.
If you’ve run into more issues with your PS4, post a comment here and we’ll try to help. Enjoy!
