My D90 stopped working: blinking "clock" sign in the top LCD panel and battery sign. no reset working, no other function working. Any clue? thanks
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.

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.

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.
