Hi! I changed the “power button” and when I plugged it back, it went on without the press of the button, and it didn’t work. Think I may have made a lousy soldering job… :/

Got a dead BL780. Pretty sure it’s the power switch as it’s been harder and harder to push to turn on. Going to attempt to replace on the board. I’m guessing that it’s a tactile momentary switch and that the board controls the power activation instead of the tactile switch being a push on/push off. Any insight would be appreciated.
