Nikon SB-29s macro speedlight

Hello, I'm having trouble with my ring flash firing. I checked the connectors, manual flash doesn't work but the Ready light blinks when I press the manual flash button. When I turn it off and on again , I hear an audible charging sound. When I take a picture the Ready light flashes as well. Everything seems normal except no flash. Maybe my tubes are out? Any idead would be greatly appreciated. Thank you in advance. mrscary

Trigger coil or a flash tube. Flash tube is easier to replace so try to replace that first. Caution before you do anything else when you open the unit locate the main 330v capacitor and discharge it before you work on the unit !

Nikon d 90 camera Nikon Speedlight SB-600 TTL Flash on auto flash fire when dont any photograph when ready red light on

This sounds like there may be a short in the control circuit that senses the flash command. First check the wiring and the circuit area where the connector feeds. check to see if the connector circuit is shorted. These are some of the basics. It could be the internal circuit board is shorted.

Yes, though it's an older flash unit and cannot be used in the iTTL mode. The "Other Flash Units" section of the D300s manual (page 350 in my copy) lists the modes in which the flash may be used. Another concern is that the flash may not work well with certain lenses. The "Usable lenses and cameras" section of the SB-29 manual (page 5) discusses this.

If you need manual, you can download the D300s manual from
