Hey everyone wrapping up a black knight, reflowed all head pins and had the game working great for about 2-3 weeks. Last night the displays wouldn't work and found the issue to be the interconnect on mpu and driver board reseated the interconnect game fired up and digit on mpu flashed between 0-6 a few times and a tiny bit of smoke came from the upper right of the driver board.
Immediately turned the game
Off , yanked both boards and inspected for burns and damage. None found. So I have an interconnect on order. But as for further inspecting what should I look for? all contitunity
Is fine on the board and have no tell tale signs of where this smoke came from. All traces still intact.
