Vivitar 283 won't flash, exept through pc terminal

My Vivitar 283 worked fine for 3 years till one day it stoped firing while mounted onto Fuji S7000 hot shoe terminal. I tried other cameras and slave trigerers but nothing worked. I can only fire it now either by pressing the test bottom or using pc terminal. Is there a way to fix this?

Thank you!

Hi if it is a Japanese 283, CAREFUL, you are working with ~300V
remove the sensor from the front. Short out the terminals at 7 o'clock and 11 o'clock with eg a paper clip, and then charge up the flash . Short the centre terminal with the one at 7 o'clock. If the flash fires, then it probably needs a replacement hot shoe from ebay. If it doesn't, it is a simple job to fix for an electronics worker. Manuals are available on ebay.
I repeat, careful with the Japanese flashes, you will have ~300 volts near you fingers, so if you are less than 100% confident that you won't blow the top of a finger (or worse), get an electronics worker to look at it.
Don't use the ebay hot shoes on a 300 volt flash, you will have the 300 volts out in the open and ready to bite you - have a look how well hidden the second contact is on the Vivitar plastic hot shoe.
Good luck the Feral Photographer

Vivitar 283 won't fire


Since the flash is working on test, it means the connection to the camera via the hotshoe is not working. With the flash on and ready light showing that the flash has charged, take a small thin copper wire and short between the the metal spring on the side of the hotshoe (in the slot) and the round metal contact tip of the hot shoe. This should cause the flash to fire if the internal connections to the shoe are working.
If the shoe is working then it must be the camera that is not working. Many modern digital cameras cannot fire older flashes directly, because the voltages on these older flashes are too high. This could damage the camera or if the camera has protection against the high voltage, that will make it impossible to fire the flash. In that case you need an adapter. These are available cheaply. You should try borrowing a modern flash to test that your camera is still working and has not been damaged, if it is a modern electronic camera.

Can the Vivitar 283 be used safely on Nikon Digital SLR Cameras?


I assume you're asking about the 283, not the DF-283 which is compatible with digital cameras.

As for the 283, yes, if you put an adapter such as the Wein Safe-Sync between the camera and the flash. Under no circumstances should the flash be mounted directly on the camera.

No the 283 is not compatible with your camera. The 283 is manual only and not TTl. The canon flash is also not compatible with your Olympus. You need an olympus compatible flash.

Vivitar 283 with new Nikon Digital camera


the nikon D80 has a 250 volts safe range and i have the same issue but readin on the internet i learned that yo can now the voltage of your flash with a voltage metter ond the hot soe.

Vivitar 283 has diferent ranges of voltages depending on the year of fabrication so older ones can achieve 300 volts and earlier have 230 volts so the best is to get a vivitar 285hv for about 75dollars or a safe sync for about 55dollars, you can find all on ebay or other brouser the safe sync converts up to 400 volts to a safe 6 volts that are yust the normal voltage for digital flashes.

Vivatar 283 and Nikon D70s


The Vivitar 283 was manufactured in China & Japan over a number of years & the specifications did change over this period.

The older Vivitar flashes had a voltage on the shoe which could reach 150 volts whilst the later ones had voltages of only 5 to 9 volts.

If you have, or can get hold of, a small voltmeter then you can measure this voltage.
Turn on your flash & let the unit charge up to 'ready' & connect the meter between the contact in the centre of the shoe & the little contact tucked away in the lip of the shoe. (DC volts not AC) There is no danger to you in doing this!
This should tell the voltage on the shoe of your unit & if it is 15 volts or less, it will be fine with your digital Nikon camera. If more than 15 volts than best not to use it.

Hope this is of some help!

Vivitar 283 flash will not work on camera.


To test everything except the camera, just short the contacts on the Wein protector. If the flash fires, the problem is in your camera, and maybe the protector did not do its job as good as expected.

Good luck

Vivitar 283 charges but fails to flash


I had the same problem with my early Vivitar 283 flash.  I discovered that the thyristor on the trigger board tested as an open circuit. 

Trying to find a replacement for a 30 year old thyristor semi-conductor proved to be fruitless. 

My solution was to purchase a broken, late model Japanese 283 flash off of ebay and transfer the trigger board to my early Japanese model. The late model thyristors could handle more heat.

Problem solved.
