Typical EOS 5D Mark III Issues We Fix
- Err 20/30 during bursts — shutter or mirror drive faults; assembly service.
- Intermittent AF or front/back focus — AF unit clean and recalibration.
- Top LCD fade or segment loss — module replacement and reseal.
- CF pin damage / SD errors — slot rebuild and controller line check.
- Hot shoe misfires — oxidized contacts or cracked solder joints; cleanup and reflow.
EOS DSLRs — Error Codes Quick Hints
| Code | Meaning | First Aid |
|---|---|---|
| Err 20 | Mechanical fault | Power cycle; reseat lens/battery; service mirror/shutter if it repeats. |
| Err 30 | Shutter problem | Fresh LP-E6; inspect blades; likely shutter replacement. |
| Err 40 | Power/electrical | Clean contacts; avoid hot-plug; board diagnostics. |
| Err 70 | Data/processing | Reset; new card; firmware/board service if persistent. |
| Err 80/99 | General/image fault | Stop use; full diagnostics to isolate shutter/sensor/firmware path. |
Pro Tips for EOS 5D Mark III
- Use UDMA 7 CF and quality SDHC/SDXC; avoid microSD adapters.
- Keep hot shoe and battery contacts clean to prevent misfires and dropouts.
- Inspect door gaskets annually to maintain sealing.
- Store LP-E6 at 40–60% charge; full cycle occasionally for calibration.
- Update firmware and verify AF microadjustment with primary lenses.
FAQ
1. The camera won’t power on or shuts off under load.
We check LP-E6 health, DC-DC rails, fuses and protection, then restore the failing stage.
2. AF is inconsistent or misses tracking.
We clean the AF unit, verify sub-mirror geometry, update firmware and calibrate with reference optics.
3. Err 20/30/99 appears intermittently.
We isolate shutter/mirror flex and main PCB paths, replace weak parts and stress-test.
4. Top LCD fades or leaks.
We fit a new status LCD and reseal to preserve dust/moisture resistance.
5. CF/SD slot errors or “Card not recognized”.
We rebuild the slot, straighten/replace pins, validate controller lines and test with certified media.
6. Stuck on logo / boot loop.
We perform a service reflash, verify boot partitions and check NAND integrity.
