Hi, again.

After shortly research I found that 580ex II has a factory problems. When HSS is turn on, IGBT-burned out. Which part I should replace to fix the problems?

We just wanted to let you know that we don't recommend do-it-yourself repairs. So, if you’re experiencing a problem with your Speedlite 580 EXII, it’s best to let a professional Canon Factory Service Center Technician do the work to keep you and your gear safe.

I think someone has to be kind here and draw a sketch showing how one can do the repair,its not fair I pay that much to canon when i bought this new only 15 month ago with little usage .

The cheapest repair is around £200 ,WTF

Hello there!
I bought  an IGBT (transistor)  (part # RJP4301) from ebay. After that I changed it. It`s cost me 5$.

PS: But after that i had to change and my bulb and some other elements.
