Depding on the brand of the remotes..... in general try the flash on M Mode. Then try the test function. I assume the receiver is conencted to the flash (i have to ask the obvious, sorry!), if so is it via a built in hotshoe on the receiver or is it via a PC sync cable?
Perhaps a quick photo of your setup might help us with your setup?
Try the camera on M mode to, perhaps try a
shutter speed of 1/90, just to make sure they work. Some Wireless remotes have had a problem in the past of firing at the camera's max sync speed. Im not saying yours will, but it will rule that out too.
Let us know how you go.
