Canon M50 Not Turning On: What It Usually Means
If your Canon M50 is not turning on, the problem is usually related to power delivery, battery contact, the battery door, or a camera lockup rather than a total failure.
In many cases, a few targeted checks can restore normal operation without repair.
The Canon EOS M50 is a mirrorless camera built around a rechargeable LP-E12 battery, a memory card, and several protective switches that can interrupt startup.
Understanding how those parts interact makes troubleshooting much faster and helps you avoid unnecessary replacement costs.
Common Reasons a Canon M50 Will Not Power On
Several hardware and user-level issues can keep the camera from booting.
Start with the most common causes before assuming a deeper fault.
- Dead or improperly charged battery: The LP-E12 may be depleted, inserted incorrectly, or failing to hold a charge.
- Poor battery contact: Dirt, oxidation, or a slightly misaligned battery can prevent current flow.
- Battery door not fully latched: The M50 uses a safety interlock that can block power when the door is open.
- Faulty charger or USB power source: A bad charger, cable, or outlet can make the battery appear charged when it is not.
- Stuck power switch or startup lockup: The camera may freeze in an off state after a card error, lens issue, or firmware glitch.
- Memory card problem: A corrupted or incompatible card can interrupt the boot process.
- Accessory conflict: Flashes, adapters, remotes, or third-party grips may interfere with startup.
- Internal hardware fault: A damaged power circuit, water exposure, or impact damage may require service.
Start With the Battery
The first step in diagnosing a Canon M50 not turning on is to remove the battery and inspect it carefully.
Check that it is an LP-E12 battery, that the contacts are clean, and that it has been charged fully in a working charger.
Reinsert the battery with the label oriented correctly and make sure it clicks firmly into place.
If the battery feels loose, remove it and confirm that the contacts and battery compartment are free of lint or residue.
Try a second battery if possible
If you have access to another genuine Canon LP-E12 or a reliable third-party equivalent, test the camera with that battery.
A second battery is one of the fastest ways to separate a battery problem from a camera problem.
When a second battery works immediately, the original battery is the likely cause.
When neither battery powers the camera, continue with the camera-side checks below.
Check the Battery Door and Power Switch
The Canon M50 will not power on if the battery door is open or not fully seated.
Even a slightly misaligned door can trigger the safety interlock and prevent startup.
Close the battery compartment door with firm, even pressure until it latches.
Then move the power switch through its positions a few times to confirm it is not sticky or blocked.
If the switch feels loose or inconsistent, the internal switch mechanism may be damaged.
Remove the Memory Card and Accessories
A corrupted SD card can keep a camera from completing its startup sequence.
Remove the memory card and try turning the camera on with no card installed.
- Power off the camera completely.
- Remove the battery.
- Remove the SD card.
- Wait 30 to 60 seconds.
- Reinsert the battery and test power.
If the camera powers on without the card, format the card in-camera after the camera is stable, or replace it if it repeatedly causes startup issues.
Also remove any mounted accessories, including a speedlite, adapter, dummy battery, cage, or wireless trigger, before retesting.
Perform a Simple Reset
Mirrorless cameras can occasionally freeze because of a temporary control-state error.
A simple power reset often clears it.
- Turn the camera off, if it is responding.
- Remove the battery and memory card.
- Press and hold the power button for 10 to 15 seconds.
- Wait at least one minute.
- Reinstall the battery and try powering on again.
This process does not erase the camera by itself, but it can discharge residual power and clear minor electronic lockups.
Inspect for Charging and Power Supply Problems
If your battery seems to die too quickly or never reaches full charge, the issue may be the charger rather than the camera.
The Canon M50 uses the Canon LC-E12 charger or a compatible charger designed for the LP-E12 battery.
Look for these signs of a charging problem:
- The charger light never changes state.
- The battery remains low after several hours on the charger.
- The charger or cable feels unusually hot.
- A wall outlet or USB adapter does not consistently power the charger.
Test the charger and cable in another outlet, and if possible, compare the battery against a known-good setup.
A charger issue can mimic a camera failure because the battery may contain too little voltage to complete startup.
What If the Camera Shows Signs of Life?
Sometimes the Canon M50 is not fully dead; it may only appear that way.
Look for status lights, LCD flicker, lens movement, or brief screen flashes when you press the power switch.
If you see any sign of power but the screen stays black, the issue could involve the display, sensor communication, or a startup fault rather than the battery alone.
Try connecting the camera to a fully charged battery, removing the card, and attaching a supported Canon lens directly to the body.
Lens and Mount Issues to Rule Out
A damaged lens or dirty mount contacts can interfere with boot-up, especially if the camera tries to initialize autofocus or aperture communication during startup.
Remove the lens and inspect the metal mount contacts on both the camera and lens.
- Check for bent pins, corrosion, or dirt.
- Clean contacts gently with a dry microfiber cloth.
- Attach a different Canon EF-M or supported adapted lens if available.
If the camera powers on with one lens but not another, the lens may be the source of the problem.
A shorted lens or adapter can prevent the body from completing startup normally.
Signs the Problem May Be Hardware-Related
If you have tested the battery, charger, battery door, memory card, and lens, but the Canon M50 still will not turn on, an internal hardware fault becomes more likely.
Common examples include liquid damage, impact damage, a failed power board, or a damaged DC circuit.
Hardware failure is more likely if you notice any of the following:
- The camera was dropped recently.
- It was exposed to moisture, salt air, or condensation.
- There is a burnt smell, unusual heat, or visible corrosion.
- Power worked intermittently before stopping completely.
- The battery compartment shows bent contacts or physical damage.
At this stage, professional camera repair is usually the safest option.
Continuing to force power cycles on a damaged body can worsen the fault.
How to Reduce the Risk of Startup Problems
Once the camera is working again, a few habits can reduce the chance of seeing the same problem again.
These steps are especially useful for travel, event work, and long storage periods.
- Use a genuine Canon LP-E12 battery or a reputable replacement.
- Keep battery contacts clean and dry.
- Store batteries partially charged rather than fully depleted for long periods.
- Format memory cards in the camera after important backups.
- Remove accessories before extended storage.
- Protect the camera from moisture and temperature swings.
Regular maintenance matters because mirrorless cameras depend on stable battery voltage and clean communication across multiple components at startup.
A small contact issue can look like a major failure if it is ignored.
When to Seek Professional Service
If the Canon M50 not turning on persists after battery, card, lens, and reset checks, service is the next logical step.
A qualified technician can test voltage paths, inspect the internal board, and determine whether the camera needs component-level repair or full replacement.
Before sending the camera in, note the exact symptoms, what you already tested, whether a second battery changed anything, and whether the failure started after a drop, firmware update, or charging issue.
Clear diagnostic history can speed up repair and improve the chance of a correct fix.
