    Thank you. I was about to make a post asking about this very part and decided to search before making a whole new post. the same part died in the same exact way. That pin blew up the internal substrate but couldn't get a schematic for anything. that part goes bad often but it's probably the fault of the design of the arrest on the circuit. Also, I thought the silkscreen said it was DV14 and not QV1?
