HELP! My Nikon D70 will not turn on!?
I went to format the memory card last night, and then I chenged the lens while the camera was still on. The I had only about a week and it worked great, but that was the first time I messed with the format button. I removed the memory card put it back and I charge the battery during the day, yet is completely out. I have no idea what to do and any advice useful: ps-here is the page that was read out last night, when everything went down http://www.kenrockwell.com/nikon/d70/d70-settings- controls-I have two batteries Top.htm and I fully charged and the other is charging now. I have two memory cards and tried to change everything. I bought it off ebay …. no manual. 24 hours left without battery in it. I think I'll have to take in. There is no indication of life … "Off" is the same as "in" No numbers, letters, lights … I think I have to take
See page 200 of your manual for instructions on how to find and use the reset button. It is assumed that in Once your camera when changing lenses, but I admit that I could not follow this policy more than a couple of times. So far, I have not caused any problems, however. In addition, if they only had the camera a week, he bought used. See if you can get some idea of the dealer or previous owner.
