Nikon d90, blinking "Error"

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

Glad to have been of help :-) Gladder that you're back up and photographing.

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.

You're seeing blown-out highlights. Those are the portions of your photo that have been overexposed and lost all detail, going pure white. This is a warning, since the camera doesn't know whether you're going for this effect. Blown-out highlights are generally considered a bad thing, and the proper fix is to reduce exposure to bring back the details. This risks losing details in the dark shadows but this isn't considered as bad, since we don't expect to see things in the dark.

That was the long answer. The short answer is to press up/down on the multiselector to cycle through the different views of your photo.

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.

The r in the display is not an error. The number after the r simply tells you how many more shots the buffer can hold before it fills up.

If you're set for AF-S, the shutter will not release until focus is achieved. You can switch to AF-C or else focus manually.

Are these pictures taken using the built-in flash and with the hood on the lens? If so, you're seeing the shadow of the lens hood.

Remove the lens hood when using the built-in flash.

The r05 is not an error. It's simply telling you that the buffer has room for five more pics. It's only a problem when it gets to 0 and stays there.

As to the other error, I'm afraid I can't help you there.

you have broken the lcd sir...
