Thanks for the nice explanation. It's very unfortunate, but good to know that you was able to bypass the supply and get the board running again. You can probably sample the chip from Texas Instrument and if you are very careful, use a paint removing heat gun, or better, find a local hackerspace that has a proper hot air station for soldering. When using hot air, just be sure to protect the parts and board around the area you are working on, especially plastic parts that easily melt.
I hope you get you board fixed!
Thanks Thomas, I will purchas the IC Quickly.
I see there also has few resistors and caps around it, Will them be blowed away or damaged? any better idea to protect them?
By the way, do you know where i can find the Allegor Brd file for Gen2?
The caps might have taken damage, but probably not the resisters. My guess is that it's just the IC.
For fixing a broken board, the board files would be a good help!
