Hey guys,
I picked up an Asteroids Deluxe upright cab and it powers on, coins up and plays but nothing on the monitor. There is no neck glow and the red led on the the monitor board is on.
So I disconnected the 15 pin connector on the power supply and started checking voltages.
The un regulated DC read read 13.5 volts
what should have been 36VAC read 15V
The 6.3VAC read 0V
The 80VAC read around 25V
The 65VAC read around 20V
The marquee bulb glows a little in the ends but not much.
If anyone can help me get this going I would really appreciate it.
It seems like this points to a bad transformer but I didnt think they ever really went bad and I am getting good voltage to the game board so it is at least partially working.
This power supply does not have the voltage selection plugs on it the connector for them is not installed.
If anyone has any ideas please let me know.
Thank You.
