580ex not flashing at all

Same symtoms as canonist's reported. Everything else seems to work except it just won't flash anymore after 2 years of great service. Same symtoms as canonist's reported. Everything else seems to work except it just won't flash anymore after 2 years of great service.

Same exact problem x6 or so at this point. Have a 580EX that is 2 years old, has been repaired three times and is down again. Have a 430 that is less than a year. Just had it repaired by Canon less than a month ago and guess what, the lights come on, but it won't flash. My little Sunpak is much more reliable. My big Canons are only good for a few months. Next purchase will be another brand. Same exact problem x6 or so at this point. Have a 580EX that is 2 years old, has been repaired three times and is down again. Have a 430 that is less than a year.

I purchased a Canon SPEEDLITE 580EX TTL Flash and with minimal use it does not work any longer. It does not flash, the led panel does not work and when i was working with the settings right before the panel went out it made a loud pop the flash went off and now nothing. Piece of junk and at 350.00 is not a good buy. Really sucks......Was using it with a canon eos20D. Do not buy a Canon Speedlite 580ex in my humble opinion.

My 580EX is 3 years old and has worked perfectly until this last week, I can get a red (adequate flash charge) light but cannot get a green light for even a single shot. Tried new alkalines and new/old rechargables. Cameras (G9 and EOS40D) do not show flash ready symbol either.
