Vita slim solid green light black screen

I’ve tried everything, disconnecting the battery, holding the power button for 5 minutes, all the button combos (which only the battery disengage one works), I even made sure that the ribbon cables were fine. The screen and sound isn’t responsive. The only thing I haven’t tried is waiting for it to drain. This happened right after I opened up the Vita to clean a button board, and the only cause I could possibly see was that I was accidentally holding a screwdriver with a magnetic tip close to the vita when turning it on to test it before I closed it up. Any help is appreciated! Hope it’s not a motherboard issue
