New Nikon d90 the memory access lamp does not stop blinking

First, turn the camera off and then remove and reinstall the battery. Turn the camera back on. If the clock and battery icons still appear, try resetting the clock. If this doesn't work, contact Nikon technical support at www.nikon.com and see what they have to say. It may require a repair but determine if the camera is still under warranty. If so, Nikon may repair it at no charge.

Since a couple of months, my "out of warranty" D90 is having a problem.

Even after shutting down the unit , sometimes (post of the time) the green led is blinking (at random speed) untill the battery is 100% down (after half a day).
Switching memory card , or formatting memory card does not help.
Even without lens , problem occurs.
I tried also a other battery pack , same problem...

Anyone has an possible reason why this happens , or a 100% working solution.

PS: D90, battery packs and charger are 100% genuine NIKON.
Regards, Rik

This may be that your memory card has a fault and the camera is trying to write to it.
Can you try another memory card?
Memory cards can develop faults.
A memory card format in the camera may help but this will wipe all your photos.

Hi rhie_honey, this is normal when you put the memory card.
Regards

Format the memory card. Press and hold the two [FORMAT] buttons until "For" blinks on the top display. Release the two buttons and then press the same two buttons again.

I couldn't find a reference to a blinking green led when the d90 is off.

I would refer you to Nikon tech support for this one.

The above link has 1-800 numbers for Nikon.

I googled my question to another web site and found my answer to my problem at no charge.

It's a deadly common problem of D90. Fixation:Simply go to the DSLR repair shop and ask them to change the power circuit board of the camera. Will take $60-70 if the board available. Reason of issue:The power control IC get short and feedback the battery power to the battery causing the draining out and other problem like the top LCD back lamp turned ON after turning on the camera. Careful:To avoid this issue in future, after full charge of the battery, do not put it in the camera right then. Wait for the battery to cool down for 5-10 min and then put it in. With the full charge, the battery hold high ampere for a short time. It could damage the power distributor IC suddenly if you put it in the camera right after a full charge.

I've seen a couple of these now that describe similar problems with the D90. I haven't seen anything from Nikon, though. Common issues like that are normally fixed through firmware updates, but there are none out for the D90. Given that it's still under warrenty, you should take it to a local Nikon dealer and let them help you.

Manual and online (you probably know) are not too helpful on problems like this. They just tell you to put in a new or fresh charged battery.

You might try formatting the card in a PC and seeing if that clears up problems.

I've had a D70 for years and I had no problems like that at all, but I always format cards when I put them in camera, and I format on the PC every so often.

WHEN POUTTING INN A MEMORY CARD ON NIKON DSLR CAMERAS THE GREEN LIGHT WILL BLINK ONE TIME .
IF IT CONTINUES TO BLINK THE CARD COULD BE BAD AND TRY TO FORMAT IT .
ALSO YOU COULD HAVE A BAD COMPRESSION BOARD.
