Just picked up 2 asteroids. Boardsets are confirmed working. When the games are plugged in the red light on the deflection board stays on and thats it. What do I look for?
The red light is the spot killer, which is basically a protection to keep a huge dot from burning into the middle of the screen when there's no deflection. Can you hear deflection chatter (kind of a clicking chattery sound) from the monitor?

Do you have any high voltage? Have you tried adjusting the brightness/contrast? The HV diode could be bad, but you need to give a lot more info or do more troubleshooting (look though the FAQ) before concluding the diode is bad.
I pulled the black HV diode out and took the ohm meter and turned it to where it would make a noise when the leads are touched. Took them and touched the wire on both sides of the diode and no sound. Does that mean there is a break in the wire??
HV diode not the likely problem. Start with reflowing all solder joints on the deflection board. A good idea even if not the problem. Then go from there. Transistors next up.
