If I did change the battery before I turned the camera off, what happens?

You will have to tell us what happens when you put a EN-EL23 battery inside the camera and you hook it up to the charger or USB. If the charger or USB is hooked up the Camera will Turn ON. The POWER LED will be GREEN. Another LED on the camera will FLASH GREEN. If this happens when you charge it you are halfway home. Change it until the flashing LED turns off. This means Battery is FULLY changed. Then REMOVE the USB or CHARGER and try to turn it on.

Usually this happens when the batteries cannot supply enough power.
Use new batteries with 2000mAh or 2400mAh power rating.

i already change new battery but nothing happen then.

Hi darciegracem, Does this happen with the MB-16 battery pack using AA batteries? If so clean the contacts on the battery pack and inside the camera. Make sure it is screwed snug to the camera. If it happen when using the two 123 batteries as well, it may need a trip to Nikon. These cameras go used for about $100 or less thus, you may not want it repaired but, rather purchase a used one from a reputable dealer. The F80/N80 is a very nice camera.

Do you have it on viewfinder or lcd screen ?

this is a dead battery issue. the batteries were probably already discharged.

k u need trun off u r camera for 10-15 mints and plz remove u r batteries and clean u r batteries with cloth and if prob still so change u r batteries

this is a firmware problem that has been happening to many digital cameras, especially koday easyshare. Either the zoom/lens is stuck or the firmware needs updating. Kodak offers to fix the problem for $50

These cameras have a internal battery that holds data for the camera to keep its settings. These batteries can be replaced but the camera has to be disassimboled to change it they should be able to be changed at a local camera shop pretty cheap.

mine did the same thing and i put new batteries in and held image review buton while pressing power and it turned on
