Question about Vivitar DF-293-NIK TTL LCD Bounce Zoom Swivel DSLR AF Flash for Nikon
I have rarely used this flash but now it won't fire. The ready and ok light are not coming on. My camera is reading that there is an external flash. I have charged the batteries. I tried pressing the test button and it fired the flash but will not again. I have read only one other review that said they have had this problem. Anyone know how to correct this? I am shooting with a Canon 60D.

There is nothing wrong with your flash unit. The regular AA batters are 1.5 v volts each- if 4 batteries are used that is a total of 6 volts for proper operation. The rechargeable batteries are 1.2 volts each and 4 will get you 4.8 volts- thats 1.2 volts short and that is probably the root of our problem .
Try recharging you rechargeable batteries and put the im one more time- if the same problem happens you will have to stick with standard AA batteries. There external 6 volt packs that will work with your flash unit0 the are a bit of an expense at first but you will save on replacement batteries in the long run,.

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

If you know basic soldering, Open the old hot shoe from base
(4 screws).Note down the position of the wires.
Try to fire the flash with shorting two trigger wires,most ly it will fire.
If the springy contact is adjustable do it.If it is not repairable, you can get metal hot shoe from ebay easily.
Caution: metal hot shoe will short circuit 4 TTL contacts (on digital camera) ,so you need to put cello tape at bottom of hot shoe with only center hole.
Hope this solves.

This is more than likely a Manufacturing problem. A lot of Vivitar cameras have this problem as well as many others that are usually not the consumers fault. Just a glitch in the technology. I alone have gone through four Vivitar cameras in the last six months. The best thing to do is contact Vivitar directly. This is there website: www.vivitar.com It is best to see if you can find the number for technical support. To see if they can give you a refund or replace it for you. I hope this helps. -Richard
