I think I fried my old 7d with an ac adapter that had a dummy battery - i think i put too high of a voltage into it. Is there an easy fix? It wont turn on. (I have tried removing CF, which actually fixed my other 7D that wasn't turning on). Wasn't sure if there is some sort of circuit breaker - that can be easily replaced? Knowing it's 2025 this is more of a fun project to make a 7d webcam and use a nice lens.
