Typical EOS 90D Issues We Fix
- Err 20/30 during bursts — shutter or mirror drive; assembly service.
- Live View AF drift or hunting — Dual Pixel AF calibration and sensor check.
- Articulating touchscreen ghosting / no touch — flex damage; assembly swap.
- SD write/read errors — slot rebuild and controller validation.
- Wi-Fi/Bluetooth pairing issues or battery drain — RF board rework and retune.
EOS DSLRs — Error Codes Quick Hints
| Code | Meaning | First Aid |
|---|---|---|
| Err 20 | Mechanical fault | Power cycle; reseat lens/battery; service mirror/shutter if repeats. |
| Err 30 | Shutter problem | Try fresh LP-E6N; inspect blades; likely shutter replacement. |
| Err 40 | Power/electrical | Clean contacts; avoid hot-plug; board diagnostics. |
| Err 70 | Data/processing | Reset; new SD 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 90D
- Use fast SDXC UHS-I (V30 or better); avoid microSD adapters.
- To sustain ~10 fps keep LP-E6N healthy and cards high-speed.
- Keep firmware current; verify AF microadjustment for key lenses.
- Disable Bluetooth when not needed to reduce idle drain.
- Protect the hinge and flex of the vari-angle LCD, especially in cold.
FAQ
1. The camera won’t power on or shuts off under load.
We check LP-E6N packs, DC-DC rails, fuses and protection, then restore the failing stage.
2. Live View AF is inconsistent.
We calibrate Dual Pixel AF, verify sensor alignment and update firmware.
3. Err 20/30/99 appears intermittently.
We isolate shutter/mirror flex and PCB paths, replace weak parts and stress-test.
4. Touchscreen or hinge is damaged.
We replace the LCD/touch assembly, flex and hinge hardware, then reseal.
5. SD slot errors or “Card not recognized”.
We rebuild the slot, straighten/replace pins, validate controller lines and test with certified media.
6. Wi-Fi/Bluetooth cannot connect or drains battery.
We service the RF board, retune antennas and verify low-power modes.
