Charge time too long.


Put in fresh batteries. Flashes are notorious battery drainers. As the batteries run down the charge time lengthens.

If the unit does not charge in about two seconds with fresh batteries then it may need service.

My sb will power on but i have no flash even when i hit the test button. I noticed it got a little warm then shut down when the problem first occured. Is it fried or fixable?


Are you using fresh batteries? Are they rechargeable batteries if so do a battery test maybe a battery is weak. With fresh batteries it still does the same thing then call Nikon 1-800-645-6689

Flash will not fire. Light indacts if fired, but no flash. Good contact and fresh batteries.


Hi Tam,

Try this:

Flash on
Flash ready.
Short out center pin to outside contact..this will fire the flash.

Sigma EF-500-DG, does not charge and does not become ready


Hello

Thank you for using FixYa for your problem

Always check the batteries first - make sure they have full charge (in the wrong way can discharge them) but if is it still giving the same fault, your flash is faulty.
It should be taken to an authorized repair centre for a repair estimate. Very few digital cameras have any user-serviceable parts.

Please rate our solutions and if you still have problems please call back for more ideas to help you

Thanks

I have not used my Metz 45ct-5 flash for over a year.


You may have to install new batteries, a few times. The Capacitor will **** the life out of the batteries as it builds up its charge. I have a Hasselblad D-Flash 40 this happened to. Bought as Mint. Not used in over 1 year. When I received it, I was absolutely pissed that I bought more ebay junk. But, I persisted. I think I went through 30 batteries, before the Capacitor rejuvenated itself. Try. Best of luck.

A: For Sigma issue:

The Sigma EF-500 flashes have very small chromed contacts for the batteries. Even though they may not look corroded, they may not power up or conduct enough power to fully cycle up. Use a polishing tip in a dremel or an ink eraser tip to clean the internal wire contacts and the flat contacts on the door. I use dielectric grease on a q-tip to apply a coat to all contacts and cleaned battery terminals to minimise future issues.

Sigma Flash EF-500 DG SUPER


I use one of my cams with a sigma 500 DG-ST in a nightclub

ive done 3 of the hot shoe connectors in the last year

look up sigma's website and find the contact info
give them a call and they should after some arguing ship you out the parts

every time i have ordered parts they try and get me to send it in for repair even though by the time i am ordering the parts the flashgun is already in bits & i tell them this they keep telling me how dificult it is to do...

for the canon fittment do the following

at the base of the flash remove the 4 screws
this removes the bottom section
unclip the wireing harness
there are 2 screws securing a small metal plate remove them

now there are 4 screws securing the small PCB, remove them, you can now take out the boot from the bottom be careful as the pins and the springs will want to come out
pay atention to the locking pin and how its orientated

swap over the broken boot with the replacement then retrace your steps to get it back together
