To reset the device, hold down the "MODE" and "ON/OFF" buttons at the same time for about 3 seconds.
Hopefully that will do the trick. if not you cant contact me for further help!

Let's force the flash to fire:
nstalls four fresh batteries.
Turn on flash, do not connect to camera
Wait until flash is ready
Get a small wire with insulation and strip both ends about 1/8".
With one end of the bare wire lead, touch/hold CENTER TIP
Contact(silver pin from flash).
Make sure flash head is not pointing at your face.
With other end touch bare wire to OUTSIDE Contact (silver on
outside of hot shoe that rides into camera hot shoe rails-this is ground).
Flash should fires, gets a flash out of the flash tube.
If not, you have flash problems.
You most likely hurt the flash by using the dome filter on top of flash.
Over 80% photographers are doing this way when shooting flash photography. And 95% for wedding photographers.
This will shorten the life of the flash.
Even more with that adapter parked onto the flash.
Hope they are helpful to all photographers.
Suggestions or comments,

It sounds like the inverter circuit or the control processor may have failed. This is normaly changed as a complete module.
Nikon, or their authorized service rep should be able to service this flash for you unless the parts are obsolete.

I have 2 SB-800s. When batteries leaked in one Nikon took forever to fix it, so they eventually sent me a refurb. Then they sent my original back. Which was great, until recently it developed this problem.
Another possibly related side effect is the modeling flash does not burst -- it only fires a single (very bright) flash.
The capacitor argument sounds likely. Coincidentally I also had a problem where the flash would fire sporadically -- but that was due to scuz buildup on the contacts.
Sorry I don't have a real solution for you.
