ERR 80
Canon Camera
Severity: CriticalWhat Does This Error Mean?
ERR 80 means the camera's electronic control system detected a fault related to image display or processing output. This is different from ERR 50 — it specifically relates to the display and output circuits. Remove the battery, wait 30 seconds, and try again.
Affected Models
- Canon EOS Rebel series
- Canon EOS 5D
- Canon EOS 6D
- Canon EOS R series
- Most Canon cameras
Common Causes
- Display circuit temporary malfunction
- Image output processor error
- LCD or EVF connection issue
- Main board electronic failure
- Moisture damage affecting display circuits
How to Fix It
-
Remove the battery for 30 seconds and reinsert.
This hard-resets all electronic systems. Most ERR 80 events are temporary.
-
Check the LCD and viewfinder for visible damage.
If the screen is cracked or shows artifacts, the display hardware may be damaged.
-
Check for moisture inside the camera.
If the camera was used in rain or humidity, moisture can affect electronics. Let the camera dry in a bag of silica gel packets for 24-48 hours.
-
If persistent, the main board or display needs professional repair.
ERR 80 that returns after every reset indicates hardware failure.
Frequently Asked Questions
Is ERR 80 the same as ERR 50?
They are similar but affect different subsystems. ERR 50 is general electronic control. ERR 80 is specifically display and output-related.
Can moisture cause ERR 80?
Yes. Water and humidity can create short circuits on the display control board. Weather-sealed bodies are more resistant but not waterproof.
