This camera has probably seen its better day. It now only functions in auto mode. None of the manual or program features work. Not sure what to do or how expensive a fix this would be. Maybe time to shop for a new version. any advice from the experts?
I had a D70 and loved it - until I got my D300s. Then I loved the D300s - until I got my D800. Cameras are like computers. Some would say they are computers. After a certain amount of time, they become obsolete. When they don't do the job for you any longer or they hold you back from being able to get the shots you want, then it is time for a new camera.
The lowest end of the current Nikon DSLR line has more power and functionality than the D70. If you can afford it, treat yourself to a new DSLR or a nice used model from one of your fellow Nikonians.
Unless what's wrong can be fixed with a two-button reset, removing the battery for 24 hours, or is a matter of cleaning contacts or reseating a connector, replacement with a used body would likely be less expensive than a board-level repair. If you're handy, search on terms like "Nikon D70 repair" and see if any of the self-help sites offer anything you can use. D70 bodies are going for about $200 in places. KEH has EX+ examples for $215. So, in order to simply stay in place, that should be your budget for any repair. If the D70 does everything you want a camera to be able to do, then direct replacement may make sense for you.
If that doesn't suit your style, there is always the option to move up to a newer body. At least, with a dead DSLR, you get to keep the lens or lenses. As for me, when my D70 dies, I will put it gently to rest along with its antecedents and move on. I love it dearly, but...
Sorry to hear of your problem. Have you tried resetting the camera by using a paper clip to press the reset button on the bottom of the camera? If the problem persists, I would suspect the problem is the mode dial. Good luck and Enjoy your Nikons!
If you have tried Marty's suggestion, resetting the camera, and still no luck, probably you can contact http://www.nikoncamerarepair.com/ I heard that they are good. But I didn't use their service myself. Good luck!
This problem could be simple to fix, or it could be really hard. It sounds like the mode dial is what is wrong, and that's easy. But it could be a circuitry problem, and on these cameras nearly all of the circuitry is on one or two major components that are expensive to replace. A D70 is only worth about $250 these days, so it rapidly becomes economically infeasible to do much in the way of repair.
I'd discuss with an authorized repair station (there's a list on Nikon's web site).
