- Store LP-E6 batteries half-charged, recalibrate occasionally.
- Update firmware and verify AF microadjustment with main lenses.
FAQ
1. My EOS 5D won’t turn on.
We inspect LP-E6 packs, DC-DC converters and fuses, then repair or replace the failing circuits.
2. Autofocus misses shots often.
We clean AF sensors, align the mirror, run firmware updates and fine-tune calibration.
3. Err 99 keeps showing up.
We isolate shutter and flex ribbon issues, test the main board and replace weak parts.
4. The top screen is blank or leaking.
We fit a new LCD panel and reseal to preserve dust and moisture resistance.
5. CF slot gives “Card not recognized”.
We repair or replace the slot, rebuild bent pins and test with certified media.
6. The camera freezes on the logo screen.
We reflash the firmware, check boot partitions and verify NAND integrity.
