Flash is not working on d90 - Nikon SB-400 Flash

Could you provide some details? How does it not work? Does the D90 not turn on? Does it take a picture but the flash doesn't go off? What exposure mode(s) are you using?

Go in menu go to bracketing /flash then set for TTL
you should work to test leave lens cap on push button on left side with lightning bolt on it.

The QTB 7500A will work with the D90. However, you will not be able to use the iTTL mode of the D90. Use it exactly the same way you've been using it with the N80, letting the flash control the exposure.

this flash will not work on the newer digital nikon cameras, the flash for d90 needs to be ittl compatible.

Not fully. It will work in non-TTL and manual modes, but it will not work in TTL mode. That is, it will work but not in fully automatic like the newer flash units.

Hi Vilas,
All of those cables will not do. Your Nikon D90 has no PC Socket. Buy a NIKON AS-15 and then just hook Flash Sync Cable to AS-15.

Yes it should. D90 has remote facility too.

that is a factory defect. very common for d90s. have it serviced.

Hi, Bad news for you.

Try this.

1. put new batteries in flash.
2. turn flash on off camera.
3. listen for capacitor to squeal (high pitched whistle). If you hear it it is charging. If not capacitor is bad.
4. Also should see flash ready light come on. If it does not same as #3 above.
5. If you pass #3 & 4# above press manual flash/check/test button on flash. No flash means bulb is out. It can be replaced.

Hope this fixed ya. Please rate. Good Luck! Comment back if you need further assistance.

All old lenses will work on the D90 the same way they work on the D80. Filters depend on the lens -- they either fit or they don't -- the camera has nothing to do with that. I wouldn't use old flashes on new DSLRs.

There really is no difference between the D80 and the D90 as far as lenses and flashes are concerned.
