Hey all, new to the forum. I Googled "Pocket Wizard Forum" and this is the first site that came up. I realize this isn't exactly what I was looking for but there seems to be some knowledgeable people here so I figured I give it a shot. Today in the middle of a on location photo shoot my pocket wizard system stopped working. At first I checked the cord going to the flash (Alien Bee 800) and it was plugged in correctly. Next I checked the test button on the PW receiver and the flash fired. Next I hit the test button on the PW transmitter and nothing. Batteries are fresh and everything on the units were flashing like normal. Next I tried different channels to no avail. Not wanting to waste my clients time I put off any further trouble shooting and spent the rest of the session plugged directly to the transmitter or using my hot shoe flash (which I totally hate using now, spoiled big time on the off camera flash look). Later at home I tried a different set up, plugged the units into my hot shoe flash with a different cable. When I switched the receiver on this time the LED's stayed on. After a minute or so they went back to blinking. Eventually I could get the flash to fire by hitting the test button on the transmitter but it wouldn't fire every time. When I put in on the camera I couldn't get a thing. I'm stumped, my next stop is checking some units on Ebay but I thought I'd see what kind of feedback I could get here before I commit to buying more units. Thanks in advance.
