OK, I picked up a Teenage Mutant Ninja Turtles.....the power supply board had a burn and repair that made it useless so I bought a Rottendog replacement. The game booted up fine and seemed to play. One note is the left sling shot does not fire and soon I smelled something. Sure enough the Q10 transistor cracked in half and the display stopped working. I replaced the transistor, checked the right sling diode (which is controlled by Q10), and started the game up again. I did not attach the special coil connector so I could see if Q10 would blow. Game booted right up, display works, and Q10 did not get hot. But as soon as I attach the connector Q10 starts to get hot. I disconnected the ground wire from the right sling coil but Q10 still gets hot.
Anyone have an idea where my short may be?
Thanks, Garry
