Question about Nikon D50 Digital Camera

Nikon D50 CHA error

The camera randomly fails to recognize the memory card. I have had it in for diagnosis & repair (camera 2+ years old). The tech said it was a problem with communication between the circuit board and the card reader. Unfortunately, the "fix" didn't fix anything. I've tried different cards without success.

This sounds curiously like the D70 problems but I'm not having success finding a significant number of other people with the same problem. Since I'm taking the camera in for round #2 of repairs (under shop warranty) what is your opinion of the problem?

    I have the same problem and after nothing but problems with Nikon cameras including Nikon's service department not honoring the 1 year warranty on my daugther's L12, I don't really trust sending my D50 to them to repair. Can I reload the original firmware to correct the problem?

    I took the card out to download the pics to my computer and after putting the card back in the camera I had the CH error message. It was that fast and permanent.



    I have purchased other cards and used the card from my brother's D50 and nothing works.

    Even after formatting with either menu or shortcut, it will display the CHA error and stop taking photos. I've used multiple cards

  • joyneville May 17, 2008

    i had this same problem with my D50 yesterday for the first time. is there anything that can be done to correct the problem or is the camera a hopeless case? it's never done this before- the shutter would close but not open if i just pressed the exposure button, if i held it down it would open and close but the camera would not capture the image? so it's a memory card problem or a camera malfunction? someone help!!!

    I bought a new 4 GB SD memory card from BlueProton (through Amazon), but when I put it in my Nikon D50, it flashed "CHA" on the LCD screen where the number of photos remaining number usually is, and wouldn't take any pictures with that card. I couldn't find anything in the D50 manual, or the field guide.

  • nicholeferra Oct 03, 2008

    I am having this same problem, but I looked and my memory card was not locked. It flashes the CHA error and I can't seem to fix this. Help

  • gregrt336 Oct 27, 2008

    Camera is 2 years old, hardly 300 pics. I cant insert a memory card fully into the camers. There seems to be a leaver blocking the way. I am thinking this is a lock that locks the card in place. But with no card in the camera i am screwed.

    Sorry, the Guest post was from me.

    After nearly a year of "repair," NIKON
    has replaced the camera with a factory refurbished D50. It was in for
    repairs three times with my local authorized repair facility and then
    three times with NIKON. Each time, it would come back "fixed" and
    "checked" only to have me reproduce the problem within a week....very
    frustrating for me and confusing to the repair shops

    I believe
    the original diagnosis was correct, "communication problem between the
    card reader and circuit board." Of course, this is rather general and
    covers everything that could be wrong. I also believe that the process
    of tracking cameras
    in for repair contributed to the false belief that the camera was
    repaired. If I was to remove the battery for an extended period of time
    (24 hours), the camera would come back to life and work...for a while.
    I believe this is the process of the repair shops (local and NIKON) --
    remove lens, card, and battery then attach these only for diagnosis and
    testing. While waiting for repair, everything is removed, the
    technician is unable to find anything wrong when he puts everything
    together.

    Finally, NIKON gave up trying to fix this camera and
    sent the replacement. Unfortunately, I have not used it much since I
    purchased a replacement DSLR, but whenever I do pull it out, it works!

    Bottom line....there is no solution for this problem other than replacement.

  • riverwalk04 Jan 27, 2009

    My camera has the same problem. The notification on the viewfinder display keeps flashing that there's no memory card - and the battery symbol (though showing fully charged) keeps blinking too. I've taken the memory card out and replaced different ones, turned it off and on, rechared the battery, and it still says there's no card and won't let me shoot.
    Grrr!
    Help!

    When I put in a SanDisk Ultra 4GB I get a CHA error. When I put the disc in another camera it works. I am presently using a 2GB and it works fine

  • Anonymous Apr 23, 2009

    I always used the same card and no problem, the card was lost and replaced and nothing but [CHA] now.

The issue is that the firmware on the d50 only recognizes FAT16. Now the problem with FAT16 is that it has a limit of 2GB. So, if you have a 4GB card, you are just SOL. There isnt anything wrong physically with the camera. Buy a smaller card.

I checked the cards, noted that they were “locked” by a sliding switch, switched them to unlocked, and tried one in the camera: it worked! A rather simple solution, it turned out.

    Thank you sir. You were correct. I don't how the slide moved on the card but it works just fine now.

  • kwood700 Dec 22, 2010

    This is absolutely true I just got a 32GB memory card and it won't work. Get error "CHA" take it out and put in my Panasonic Lumix and it works fine. Put a 1 or 2GB back in the Nikon D50 and it works. anything above 2GB doesn't work at all. New camera or just stock up on 2GB memory cards.

Similar problem with a D70S.  I finally realized that just ejecting and reinserting the card would do it.  Even if in the middle of shooting it might stop recognizing the card and read FOR or CHA but if I just ejected and reinserted, it would work without losing any images.

I cant insert a memory card into the camera. the littel switch that checks to see if it is locked will not retract to let my card slide all the way down. I did manage to get a micro card adapter to go in all the way and the micro card works. I now just remove the micro sd from the adapter and put it in a micro adapter un my PC to pull pics. The adapter stays in the camera. Sucks, because Wolf camera bimbos just said we can send it off and get it fixed, for 178$ and 6 to 8 weeks.

What does CHA mean


Nikon says this about CHA:


When a Memory card is inserted into a D-SLR camera, the camera checks the card for compatibility and usability. There are three possible results of the test:

1) Camera detects valid Memory card, displays number of remaining images in top LCD

2) Camera displays "FOR" in top control panel LCD. The camera has detected a valid disk partition map, but was unable to read the first sector of the Memory Card. Formatting the memory Card using the cameras format option, should resolve this condition and allow the Memory card to be used.

3) Camera displays "CHA" in top LCD. The camera has detected an invalid partition type or is not working properly. Reformatting the memory card may allow it to be used. If an approved memory card causes the camera to display the "CHA" indicator contact the memory cards manufacturer for assistance.

(Nikon's list of "approved" memory cards can be found here.)

Please note that the default disk format used in Windows XP is FAT32 and if a card is formatted with this setting on an XP system, a D1 series camera will report "CHA". Reformat the card as "FAT" to use in the D1 series camera.


When the CHA error is shown, typically the camera will freeze and require that the battery be removed from the camera before it can take another picture. After that picture has been taken, the camera freezes up again for many owners.

Some owners have success removing and either re-seating or inserting a new memory card in the camera.

Some owners have success clearing the error by removing the lens and then reinstalling.

The key to these "fixes" is that they don't all work for everyone. You might need to return the camera to Nikon for repair. You can arrange for Nikon service here.

I hope this helps and good luck. Please rate this reply
. Thank you.

What does ''CHA'' mean on my Nikon D50 I can't seem to take any photo's


You haven't provided enough details to be sure of the problem, but I suspect you have either bought a new memory card that is either the wrong type or too large for that camera. If it is still the original memory card that you first used with your camera, try reformating the card.

D50 cannot use a 4gb card??? I use 1gb, 2 gb and no issues, now bought a 4gb card and get a CHA indicator on camera and will not shoot pictures. Can this camera be programed to accept a 4gb or larger...


No, the D50 will not (as you've discovered) accept an SDHC memory card (anything bigger than 2gb is SDHC). I haven't found a firmware upgrade for the D50 to rectify this issue, either. I own a D50 also, and love it, but bigger cards would be nice.

Memory not working in my D50.


The D50 will only accept up to a 2gb SD card. Cards of 4gb and larger are a newer type of SD card, known as SDHC (secure digital high capacity). At the time the D50 was made, SDHC cards weren't on the market. In short, if it is larger than 2gb it won't work. There's also no upgrade that I've found to handle SDHC cards in the D50, either. I love my D50, except for the card limitation.

I have a Nikon D50 with an error message "CHA"


This error indicates the following:
This card cannot be used (CHR) blinks.
Problem(s)
Error accessing memory card
Unable to create a new folder (on card)
Card has not been formatted for use on D70

Try another card
Format the card using your D70 (all images will be erased)
Check the card for visible damage or poor contacts.

You may have inserted a memory card that was been used in a different camera or the formatting process did not complete successfully.
I hope this helps.
