How to Fix Common Nikon D90 Errors: A Comprehensive Guide

The Nikon D90, a beloved DSLR, can sometimes throw error codes or exhibit unexpected behavior. This guide provides troubleshooting steps for common Nikon D90 errors, helping you get back to capturing stunning photos.

Understanding Nikon D90 Error Messages

Error messages on your Nikon D90 often indicate a specific problem. Before diving into solutions, understanding what the error means is crucial. Consult your Nikon D90 manual for a complete list of error codes, but here are some common ones:

  • Err: A general error, often requiring more specific troubleshooting.
  • fEE: Indicates a problem with the lens aperture ring setting (typically with older lenses).
  • CHA: Problem with the memory card.

Troubleshooting Common Nikon D90 Errors

Here’s a breakdown of common Nikon D90 errors and how to fix them:

1. General Error (Err)

This is a catch-all error, so systematically troubleshoot:

  • Turn the camera off and on: This simple step often resolves temporary glitches.
  • Check the lens connection: Remove and reattach the lens, ensuring it clicks securely into place. Clean the lens contacts with a microfiber cloth.
  • Check the battery: Ensure the battery is fully charged and properly seated. Try a different, fully charged Nikon EN-EL3e battery if available.
  • Check the memory card: Remove and reinsert the memory card. Try a different memory card to rule out card issues.
  • Reset the camera: If none of the above work, reset the camera to its factory settings via the menu. Note: This will erase your custom settings.

How to reset: Go to the Setup Menu (wrench icon), then choose “Reset Shooting Menu” or “Reset Custom Settings”, depending on what you want to reset.

2. fEE Error (Aperture Ring Error)

This error occurs when using older lenses with an aperture ring. The D90 needs the aperture ring set to its smallest aperture (usually f/22 or f/32, indicated by an orange marking) and locked in place.

  • Set the aperture ring: Rotate the aperture ring to the smallest aperture and ensure it clicks into the locked position (if the lens has a locking mechanism).
  • Use newer lenses: Consider using newer AF-S or AF-I lenses, which don’t have an aperture ring, for easier operation.

3. CHA Error (Memory Card Error)

This error indicates a problem with the memory card.

  • Reinsert the card: Remove and reinsert the memory card, ensuring it’s properly seated.
  • Try a different card: Test with a different memory card to rule out a faulty card.
  • Format the card: Format the memory card in the camera’s menu. Note: This will erase all data on the card, so back up any important files first.

How to format: Go to the Setup Menu (wrench icon), then choose “Format Memory Card”.

  • Check card compatibility: Ensure your memory card is compatible with the Nikon D90. The D90 supports SD and SDHC cards.

4. Image Review Problems

Sometimes, you might not see images properly during playback.

  • Check the playback settings: Make sure the playback settings are configured correctly in the menu.
  • Corrupted image files: Corrupted image files can cause playback issues. Try viewing the images on a computer to see if the problem persists.
  • Memory card errors: As above, memory card issues can also affect image review.

5. Autofocus Issues

If your D90 is struggling to focus:

  • Check the focus mode: Ensure the camera is set to autofocus (AF) and not manual focus (MF).
  • Clean the lens: A dirty lens can interfere with autofocus. Clean the lens elements with a microfiber cloth.
  • Use the correct focus point: Select the appropriate focus point for your subject.
  • Insufficient light: Autofocus can struggle in low light. Use the AF-assist illuminator (if available) or provide more light.

Other Troubleshooting Tips

  • Update Firmware: Check the Nikon website for firmware updates for your D90. Firmware updates can resolve bugs and improve performance.
  • Clean the Camera: Dust and debris can cause various issues. Regularly clean the camera body, lens mount, and sensor (carefully!).
  • Professional Repair: If none of these steps resolve the issue, consider taking your Nikon D90 to a qualified camera repair technician.

Preventing Future Errors

  • Use High-Quality Memory Cards: Invest in reputable SD cards to minimize data corruption.
  • Handle with Care: Avoid dropping or exposing your camera to extreme temperatures or humidity.
  • Regular Maintenance: Clean your camera and lenses regularly.

By following these troubleshooting steps, you can resolve many common Nikon D90 errors and keep your camera in optimal working condition. Remember to consult your camera’s manual for more detailed information and specific error codes.
