Why a Canon EOS R50 Not Turning On Issue Happens
A Canon EOS R50 that will not power up is usually dealing with a basic power problem, not a major failure.
The issue can come from the LP-E17 battery, battery door, charger, memory card, lens contacts, firmware, or a deeper electrical fault.
The key is to isolate the problem methodically so you do not overlook a simple fix before assuming the camera needs service.
Check the Battery and Charger First
Most startup problems begin with insufficient power.
The Canon EOS R50 uses the LP-E17 lithium-ion battery, and even a partially charged battery may not be enough if it is old, damaged, or not seated correctly.
What to verify
- Confirm the battery is an authentic or compatible LP-E17 battery.
- Inspect the battery for swelling, corrosion, or debris on the terminals.
- Charge the battery fully using the Canon charger or a reputable third-party charger.
- Try a second known-good battery if one is available.
- Check that the charger indicator shows normal charging behavior.
If the camera powers on with a different battery, the original battery is likely worn out rather than the camera failing.
Make Sure the Battery Is Installed Correctly
The EOS R50 may appear dead if the battery door is not fully closed or the battery is not locked into place.
The camera will not power up if the door safety switch is not engaged.
How to inspect the battery compartment
- Open the battery door and remove the battery.
- Look for dust, bent contacts, or residue inside the compartment.
- Reinsert the battery in the correct orientation until it clicks.
- Close the battery door firmly and listen for a secure latch.
- Test the camera again with the power switch set to On.
If the battery door does not latch cleanly, the camera may not receive power even when the battery is charged.
Confirm the Power Switch and Startup Behavior
The Canon EOS R50 has simple startup behavior, but it still helps to check whether the camera is actually receiving power and just not displaying an obvious sign.
A dim screen, an inactive EVF, or no response at all can point to different causes.
Try these quick tests
- Move the power switch fully to the On position.
- Wait a few seconds after switching on, especially after a battery swap.
- Press the shutter button halfway to wake the camera.
- Remove and reinstall the battery, then try again.
- Use the camera without a lens to rule out a lens communication issue.
If you hear a brief sound, see a status light, or notice any display flicker, the camera may have partial power and a removable accessory problem rather than a total failure.
Remove the Memory Card and Try Again
A corrupted SD card can occasionally prevent a camera from starting normally or make it look unresponsive.
The EOS R50 supports SD cards, and startup issues may appear when the card file system is damaged or the card is physically failing.
Memory card troubleshooting steps
- Turn the camera off and remove the battery.
- Take out the SD card.
- Reinstall the battery and attempt to power on the camera with no card inserted.
- If the camera starts, test with a different SD card.
- Format the card in-camera only after confirming it is readable and backed up.
If the camera starts without the card, the problem is likely with the card rather than the body.
Inspect the Lens and Mount Area
Although the camera body should still power on without a lens, a communication issue between the RF mount contacts and the lens can sometimes create confusing symptoms.
If the camera tries to start and then shuts down, the lens may be contributing to the problem.
Lens-related checks
- Detach the lens and check the mount for bent pins or dirt.
- Clean the electrical contacts gently with a dry microfiber cloth.
- Try the camera with no lens attached.
- Mount a different compatible lens if available.
In many cases, removing the lens helps reveal whether the issue is with the body or the lens electronics.
Look for Overheating or Protection Shutdown
The Canon EOS R50 may refuse to start or may shut down quickly if it has been exposed to heat, moisture, or impact.
Internal protection circuits can prevent startup to avoid further damage.
Signs of a protection-related problem
- The camera was recently used in hot weather or direct sun.
- It was stored in a humid environment or exposed to rain.
- It was dropped, bumped, or packed tightly in a bag.
- The battery area or card slot smells unusual or shows visible damage.
If overheating is suspected, remove the battery and card, leave the camera in a cool dry place, and let it sit for several hours before testing again.
Check for Firmware or Settings Issues
Firmware corruption is uncommon, but it can happen after a failed update, battery interruption, or file issue.
Settings-related problems are less likely to stop the camera from powering on entirely, but they can make the screen appear blank if brightness or display behavior is altered.
What to try after power is restored
- Reset camera settings if the body becomes responsive.
- Check display brightness and auto power-off settings.
- Review firmware version on Canon’s support page once the camera is operational.
- Update firmware only with a fully charged battery.
If the camera never gets far enough to access menus, the issue is more likely hardware than firmware.
Use a Structured Power Reset
A simple power reset can clear temporary glitches.
This is especially useful if the camera froze during startup or after a battery change.
Power reset sequence
- Turn the camera off, if possible.
- Remove the battery and SD card.
- Wait at least 60 seconds.
- Press the shutter button once to discharge residual power.
- Reinsert only the battery and try powering on.
- If successful, add the SD card back afterward.
This process helps separate a temporary lockup from a persistent failure.
Identify Signs of Hardware Failure
If the Canon EOS R50 still will not turn on after battery, card, lens, and reset checks, the body may have a hardware fault.
Common causes include failed internal power regulation, damaged contacts, liquid intrusion, or a mainboard issue.
Indicators that service may be needed
- No lights, sounds, or screen activity with a known-good battery.
- The camera only powers on intermittently.
- The battery door latch is damaged.
- There is visible corrosion or water damage.
- The camera stopped working after impact or a major firmware interruption.
At that stage, professional repair is usually the most reliable next step.
When to Contact Canon Support or a Repair Center
If your Canon EOS R50 not turning on problem remains after basic troubleshooting, Canon Support or an authorized repair center can test the body more thoroughly.
This is the best option when you suspect internal electrical damage or want to protect warranty coverage.
Before you send it in
- Record the exact symptoms and what you already tested.
- Remove accessories, cards, and the lens before shipping unless instructed otherwise.
- Use the original box or secure packaging.
- Back up any images from the SD card if possible.
Providing a clear description of the failure helps technicians isolate the cause faster and reduces turnaround time.
How to Prevent Startup Problems in the Future
Routine care reduces the chances of another startup failure.
Lithium-ion batteries, memory cards, and exposed contacts all benefit from careful handling and storage.
- Keep batteries charged and rotate older batteries out of heavy use.
- Store the camera in a dry, cool case with silica gel when possible.
- Format SD cards in the camera after backing up files.
- Avoid removing the battery while the camera is writing data or updating firmware.
- Clean the battery and lens contacts periodically with a dry, lint-free cloth.
Small maintenance habits make a noticeable difference in long-term reliability, especially for mirrorless cameras like the Canon EOS R50.
