相机无法开机
当电源开关处于“开启”位置时，相机无反应。
检查电池
为相机安装新电池，以确保问题并非由电池电压过低引起。
电池触点
检查电池仓内外部的触点。如有任何腐蚀迹象，应将其彻底清理。
反光镜卡死
相机机身内的反光镜卡在抬起位置，挡住了取景器。按下快门按钮后，反光镜无法移动，或仅有轻微移动。
反光镜电机齿轮
最可能的原因是反光镜电机齿轮损坏。这是一个压装在反光镜箱附近小型电机轴上的塑料齿轮。它驱动着相机的许多核心功能，包括反光镜运动、快门上弦和光圈缩放。当齿轮失效时，所有这些功能都会停止。按下快门按钮通常会听到电机轴空转的嗡嗡声，但除此之外几乎没有其他反应。如需修复此问题，请参阅 ZX-5n 设备页面上的 反光镜电机齿轮 维修指南。
反光镜驱动杆
反光镜驱动杆位于与反光镜电机齿轮相同的区域，负责在曝光期间移动反光镜。如果该部件断裂，反光镜会卡在抬起位置，但其他所有功能应能正常运作。按下快门按钮时，你可以看到并听到快门释放的声音。该问题的 反光镜驱动杆 维修指南也可在 ZX-5n 设备页面上找到。
自动对焦断续
半按快门按钮时，自动对焦功能时断时续。
更换镜头
如果你有其他镜头，请尝试更换镜头。如果问题消失，则说明故障出在镜头而非相机上。
电触点
此问题可能是由镜头和相机机身之间的触点脏污引起的。将镜头从相机上拆下，并清洁镜头卡口和相机机身内的触点。
快门按钮
快门按钮/开关内部的触点可能会随着时间的推移而氧化，导致接触不良。拆下顶盖以接触到开关，开关可以被拆解并清洁。
快门释放断续
完全按下快门按钮时，快门无法持续释放。
快门按钮
快门按钮/开关内部的触点可能会随着时间的推移而氧化，导致接触不良。拆下顶盖以接触到开关，开关可以被拆解并清洁。
闪光灯无法弹出
按下按钮后，闪光灯无法完全弹出。
闪光灯支点
驱动弹出式闪光灯的弹簧安装在一个小型塑料支点上。该支点容易开裂，这会释放弹簧的张力，导致其无法再为闪光灯提供足够的支撑。你可以在 ZX-5n 设备页面上找到 闪光灯支点 的维修指南。
相机曝光选择错误
相机在自动曝光模式下仅选择最快的快门速度和/或最小的光圈。
测光元件故障
用于测量场景光线强度和分布的测光元件可能需要更换。可以通过拆除顶盖进行接触，该元件位于目镜和棱镜之间。

I’ve successfully completed the mirror motor repair before but when i tried on another camera it resulted in it constantly firing the shutter without fully pressing the button. I was wondering if you knew what was going on and how you would go about fixing it.
Whenever i have the batteries in and close the battery door it automatically fires about 10 consecutive shots and whenever i change the dials or turn the camera on and off it happens. I’m lost.
Thanks in advance the guide was great!

I've had one camera do this to me so far. My guess is that the camera is cycling and trying to find its "home" or "ready to fire" position. The feeler contacts on the green gear are part of this. But it can't find home and keeps cycling for a set amount of time before it stops. I took it apart, checked it, and put it back together three times without any improvement. I chalked it up to some other electrical failure in the system and declared it a "parts" camera.

Your guess was correct. I took apart the camera after I commented and found that the contacts on the green gear was bent out of place so I bent them back and reassembled the camera which solved the issue.
But when I tried the autofocus it wouldn't work. I confirmed with another camera that the lens wasn't the issue. Cleaning the contacts didn't work. Do you have any clue on what the problem might be? Otherwise the camera works fine. I yet again lost.

Oh awesome! Glad you worked out that issue.
Regarding autofocus, the repair for the mirror generally stays away from the autofocus system so I doubt that you messed anything up with the sensors or the motor. It's always possible that a wire got resoldered in the wrong spot so I would double check that. I have had several cameras with shoddy shutter buttons that would fire the shutter and/or engage autofocus inconsistently. But the switch is cleanable. Desolder it from the flex (be careful not to melt all the plastic nearby), and pop the metal top off. Use some IPA to clean any oxidation from the copper contacts and it should work like new.
If you have a cable release for the camera, that can also help diagnose the issue. Connect the cable release and half press the button. The autofocus should engage. If it does, then the shutter button on the camera is likely the issue. If it doesn't, then the problem is elsewhere.

Before I try anything I should probably properly explain the situation. The camera shoots fine but whenever it takes picture it doesn't correct the focus and instead just takes blurry pictures. The autofocus never engages. Otherwise the camera works fine. I was wondering if that would be a completely different problem from the solution you gave.
I'm just speculating at this point in order to avoid taking it apart for the fifth time and causing more problems.
