Have you tried using the wireless mode? Even if there is a problem with the hot shoe interface, it might still work using the wireless mode. To do this you have to set both the camera and the flash. On the D70, under the menu with the icon that looks like a pencil, select Flash Mode|Commander Mode|TTL|OK. On the flash, hold down the Zoom and [-] buttons to get the CSM menu. When you see the zigzag arrow, push the Mode button to turn on the wireless mode.You may have to use the [+] or [-] buttons to cycle through the menu to find the zigzag arrow.

Now you should be able to use the flash detached from the camera. Just pop up the D70 flash, which will tell the SB-600 what to do via light pulses. There are other settings that may be required (channel and group settings must match between camera and flash) and be careful not to block the light sensor on the side of the SB-600. If the wireless system is still working, you may find you like it better than hot shoe operation.

Sorry for the long answer, but this is complicated.

Some photo editors will allow you to set them up to display the date on the photo.

HOWEVER on all digital cameras:

The date taken is part of the image data that is stored in the file, but not as part of the image. If you print directly from the D70, you can set the date and data to print in one of the menus, but this only applies if you print from the camera. There is no way to actually put the date on the image like there used to be in some film cameras. Since the "picture" is now just a set of computer data bits stored on a card, disk, or other medium, the actual picture is defined by the jpeg standard, which is part of the ANSI/ISO/IEC organization. A camera manufacturer could add an extra bit of hardware to generate some kind of laser mark on the digital sensor in the camera, but I'm not aware of any camera that has this. For sure, the D70 does not.

In the various softwares that you can buy to read the file, the information in the file (like the date) can be interpreted and printed any way the software is programmed, including putting it somewhere on the printed output.

you need to go to your cameras menu and set your flash function to m ( no to ttl) set it in full M and then it works hope it works that works for me i had the same problem

If you shoot in Auto mode, the camera will not allow you to turn off the flash when it senses that it is needed.

To use the camer without the flash, change the mode to Program ("P"). Once it's in P mode, the flash will not fire as long as it's in the down position. When you want to use the flash, press the speedlight release button (the one with the little lightning bolt near the mode select dial).

I had this problem a while back, but was fortunate to get it fixed under warantee as it was less than six months after Nikon repaired my D70 for the "blinking green light of death" fault.

I'm afraid this is a repair job for Nikon or an autorized workshop. It is most likley the flash tube. If you fancy taking your camera apart (I warn you it would be a fairly difficult job) then please be aware that you may get a significant electric shock from the flash capacitor, which will remain charged.

Unfortunately, you may have a faulty flash pcb (printed circuit board) The part is around 50$ plus installation 200+ total repair cost. A work around would be to use an external flash unit from the hot shoe

According to my information, the camera may need a new flash PCB (printed circuit board). Check the repair service search on this site for someone in your area. The part number for the circuit board is: 1S014-020-1 and runs about 50$

This is a known problem that is being repaired FREE of charge by Nikon. Go here for a form to fill out: http://www.nikonusa.com/email_images/nikonusa/service_advisory/d70.html
