I had a SDB (originally from Harlem Globetrotters) in my Mata Hari and it worked for a while. Recently, my 1000 chime and Bottom Left Pop Bumper stopped working. Since I knew the issue was isolated to the SDB, I figured I would replace the transistor even though they tested good (tip 102s) and after doing so, the game fails to boot.
I replaced Q6 and Q8
I get one solid green light on the Alltek MPU and no boot. What could I have done by simply replacing these transistors which render the game in this position?
