What Causes a Black Screen in Digital Cameras and How to Fix Them
Knowing what causes a black screen in digital cameras and how to fix them can save you from costly hardware repair services. This is what can happen to a digital camera if you overcharge the battery but there are other reasons too. The first step is figuring out whether it’s caused by software or hardware.
Insider Tip
A dead pixel receives no input from your camera.
Common Black Screen Causes
There are several reasons your camera might be displaying a black screen. A loading screen causes enough despair in creatives. Having the camera you bought suddenly look like the model cameras you looked at on display can cause a lot of panic. Being able to troubleshoot and fix the issue helps immensely.
How to Spot a Dead Pixel
A dead pixel receives no input from your camera. This can happen through physical damage or due to many other factors. You can use software to help spot dead pixels by taking several photos with varying colors and patterns. Use the zoom settings in your editing software to determine where dead pixels are by spotting the “blank” spots. Zoom settings are great for spotting abnormalities.

Zoom settings are great for spotting abnormalities.
Check Your Battery Health
Poor battery health can cause problems across your entire camera. Make sure that you remove the battery cover regularly to check for damage. The battery compartment can get filled with debris that impedes its job to power your camera. The battery cover itself should be cleaned regularly, as well. You can generally find the battery cover near the USB in most cameras.
Checking for Black Pictures
There is a difference between a blank screen, a loading screen, and a screen plagued by hot pixels. Understanding the correct terminology can help you better diagnose the issue. If your blank screen shows all of the information from your camera’s software, your settings are off. Black pictures can make it seem like you have a damaged screen, especially if you’re an amateur. Tweak your settings and hit that shutter button until you get it right.
Physical Damage to LCD Screen
Several types of damage can spell disaster for your display screen. Electrical components are sensitive and fragile. Dropping your camera can be enough to cause a black screen issue. If you’ve recently damaged your camera body, that might be why the display screen is completely black. You may want to check what causes distortion in digital cameras for further information on this.
Issues with Software Updates
Not staying current with software updates can cause significant trouble. It is easily rectified by getting the software updates caught up, however. Be prepared to go back to the default factory setting for your camera if you’ve let the software updates pile up for too long.
Warning
Poor battery health can cause problems across your entire camera.
F.A.Q.
How do I fix a dead pixel?
Unfortunately, a dead pixel will not recover on its own. There are some troubleshooting methods, but a dead pixel typically calls for professional repair.
Is a stuck pixel permanent?
Unlike a dead pixel, a stuck pixel might be fixable in some cases. Restoring a stuck pixel is never a guarantee, however. You should always have your camera looked at by camera repair specialists to be sure.
Will a dead pixel spread?
A dead pixel won’t generally spread to adjacent pixels since it’s a single pixel that has lost power. If it does, you will need to replace the screen as quickly as possible.
Are white spots from defective pixels?
Generally speaking, yes. A cluster of stuck pixels can cause white spots. There are a few other reasons white spots could be appearing, however.
