I recently got a Yongnuo YN565ex on Ebay for the usual price. It's quite a good flash considering the price. It has one particular flaw; Quality Control.
Purchased in November 2011, mine was working fine until 3 day ago. The problem wasn't with the LCD or Control buttons, that part was still working perfectly. The flash was misfiring; It would only fire 1 out of 10 time. I could hear a small "click" sound inside the flash head, so it was "trying" to fire.
The good new is that most seller offer 12 month warranty. But that's not "free". Paying shipping back to China would cost me about $20 to $40 CAD. Shipping by "ground" would probably take a good 1 month just to get there, and another 2-3 week to get back here.
The solution : repair it myself. I've been doing hobby electronic for a while now, so soldering wasn't a problem.
Luckily for me, some good folk already did all the hard work of finding the common problem of this flash :

I'm here to let you know that this fix take about ~30 minutes to do if you take your time, and it works perfectly. My flash is firing just like when it was new. Considering I've used quite a beefy transformer this time, it will probably never die like that again. _________________ Body : Canon 5d Mark II, Canon 50d
