eBikes.ca blown controller pictures

I recently purchased a bad controller from a clearance sale from ebikes.ca. Occasionally, they will post ads on Endless-sphere.com to sell lots of returned or damaged components. They can range from bad motors to old model Cycle Analysts to bad controllers. I bought the 9 Continents motor and the Infineon 35A 48V controller then. I opened it up to take a look and it looks perfectly brand new! Of course, according to them, it doesn't work so I need to troubleshoot it and replace the bad FETs.
