PL 06A does not work when the yongnuo RF 602 receiver is plugged in to the sync cord plug in the back. Even the test button on the powerlight does not work. even when using test mode from the transmitter it doesn't fire the powerlight. The sync cord itself works perfectly. My wireless receiver needed a plug so I bought a metal one. The optical slave works good on it also, just the wireless trigger/receiver doesn't work.
Guess it is my wireless stuff that needs replaced???
I'm using a Canon 50D
