Need to find a photo capacitor for a sb-600 flash

the bulb has likely blown -

need to replace bad capacitor on dm board witch look like leki a cable box , this is inside the tv 7 bad capacitor 1000uf at 25v original on tv are 1000uf at 16v

If it is a whining noise that increases in pitch, that is the capacitor that powers the Xenon strobe that is in the flash. The whine might be a little less with fresh batteries, but it is normal and unavoidable.

I believe that there is a safety feature built in that if the voltage in the capacitor gets too large the flash will fire, to prevent damage, could be this that is faulty, if it is a new main circuit board is required.

check wire connection to capacitor measure voltage on it/
Be carefull high voltage!!!

Hi, you should use a capacitor with same capacitance of 1000uF, but you don't have to stick to the original voltage spec. 1000uF 10V means it can withstand 10V load. 1000uF 50V means it can hold 50V for the same capacitance. Today I fixed my friend's and for that I used 1000uF 35V from RadioShack. It perfectly works - and it's better. But you shouldn't use 1000uF 5V - by now you already know that :)

The capacitor may be weak, or there is a problem at the component level that is not allowing the inverter to reach full voltage.

The flash will need shop service.

Those Xenon flash tubes last for a long time. You likely need a new flash PCB (printed circuit board). Typically, the trigger coil is at fault when you get the ready light but no flash

I had the same issue. The flash is set to go off, the camera assumes it went off, (as the record metadata shows) but it doen't go off at all, and the piture is underexposed.

I bought the 100 page repair manual, which is ONLY a dissassemble/reassemble manual with NO diagnostics. (Got it on ebay) So I was atleast able to get to the capacitor and flash bulb. I saw 300V across the capacitor leads, and the same 300Volts across the flash bulb leads. SO I am assuming that there is a transistor or relay that drops to ground to fire the flash that isn't working, or the electronic signal to drive that isn't working.

It seems most people replace the entire flash circuit board(which is near the capacitor under the left hand side). But it seems Nikon only sells parts to it certified repair facilities.

Ugh.... Looks like I'm buying a SB-600, as this is the cheepest solution. Too bad, because the on-board flash is more than decent. I hope the SB-600 thrills me enough to change my mood. :)

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 !
