DIZ Power Cable connected wrong side.....
Hello,
i Build a DIZ Module few days ago and it works perfect. But today accidently i connect the power cable with the wrong side. The Module smokes a little bit in the area of the Power connector. I try to figure out whats burned but i cant find the problem. Is the pcb maybe broken?
I hope someone can help me.
Thanks a lot.

The TL072 was broken. Today i build it again with a new pcb and the IC2 i checked with my Multimeter and it was ok but i don´t know how to check the IC1 and U5 so i changed both and now it works!
Thanks
