after using a SSC (USWOH)modified lantern for two hours it shut off, about 20 seconds later it came back on but would not turn off or switch into high/low
I took it apart again and noticed on of the IC had a hole in it...
any idea why this would have happened?
any suggestions on a new multi level buck driver for the lantern?
here's a pic of the board
