While playing my APB machine the lights on top of the game are supposed to work like the lights on a real police car when I hit the siren button. But when I hit the button on my game during play, the blue light is on and stays solid and only the red light flashes. Is this right?

In this Youtube video of someone elses game, both lights flash when the button is pushed, but not mine: http://www.youtube.com/watch?v=G-AfAhnHnq4

Any ideas?

my guess is Q1 (2N5756) is shorted open and needs to be replaced with a NTE 5642.

look on the Triac PCB Schematic Diagram in the manual. you could buy two and just replace both Q1 and Q2. i dont think the U1/U2 MOC 3011's are bad but you could replace them too with a NTE 3047's while you're at it. reflow any cold solder joints too.

if you want to send me your board i will rebuild it or send you a 100% working one. i charge 10 bucks plus parts and you get shipping, PM me...
