EOS DSLRs — Error Codes Quick Hints
| Code | Meaning | First Aid |
|---|---|---|
| Err 20 | Mechanical fault | Power cycle; remove battery/lens; service mirror/shutter if repeats. |
| Err 30 | Shutter problem | Fresh LP-E19; inspect blades; likely shutter replacement. |
| Err 40 | Power/electrical | Check contacts; avoid hot-plug; board diagnostics. |
| Err 70 | Data/processing | Reset; new card; firmware/board rework if persistent. |
| Err 80/99 | Image/general fault | Stop use; full diagnostics to isolate shutter/sensor/firmware path. |
Pro Tips for EOS-1D X Mark III
- Use CFexpress Type B cards with high sustained write; avoid adapters.
- Keep hot shoe, LAN, and USB-C contacts clean to prevent dropouts.
- Replace door gaskets periodically to maintain weather sealing.
- Store LP-E19 partly charged; run full cycles for calibration occasionally.
- Update firmware and verify AF microadjustment with main lenses.
FAQ
1. Camera won’t power on or dies under load.
We test LP-E19 health, charger comms, fuses, and DC-DC rails, then rework or replace the affected circuit.
2. AF is inconsistent at 16–20 fps.
We clean the AF unit, check sub-mirror geometry, update firmware, and perform AF calibration with a reference lens.
3. Err 99 appears intermittently.
We isolate shutter/mirror flex and main board paths, reseat or replace failing components, and stress-test at high FPS.
4. Top LCD segments missing or leaking.
We replace the status LCD and reseal the top cover to keep weather protection intact.
5. CFexpress “Card not formatted”.
We rebuild the slot, replace bent pins, verify controller lines, and test with known-good media.
6. Camera is stuck on the logo.
We perform service-level reflash, verify boot partitions, and check NAND/SD storage integrity.
