I thought I was getting confertable with these temermetal babies. But I feel Like I have No clue and have learned nothing. So I am looking to see if anyone can help me.
Both the Asteroids Deluxe and Asteroids games that I have seem to have the same issue. The game plays blind, no picture. The spot killer light is on and the neck tube is glowing. All fuses are good and both game boards have +5.15 to each board. There are no sounds on startup in test mode and there are no flashing lights. So It seems to pass the test mode. you can coin up and play blind. All buttons seem to work and can hear the sounds of the game as I play.
For the AD, I checked the Bridge rectifier and seemed to be bad in cuirct but good out of cuircut. I replaced anyway along with the bottom caps on the chasis. Also checked the D100 diode. Still nothing.
Looking on the foums I was that folks where checking to board both with AD and AC so not sure which way but the folowing are the voltages that I got even with a new battery with the test switch on from the coin door. Not even sure If Im checking correctly but this is the numbers:
Asteroids AC DC Asteroids Deluxe AC AD
-------------------------------------------------------------------------------------
z out 3.4 1.75 2.9 1.56
x out 0 8.91 28.9 13.45
y out 20.5 9.51 29.0 13.46
so know I have no idea what to do. if its the board, the monitors, I am even second quessing if I'm using my meter corrctly. So I walked away from it for today and thought I would get some ideas from you folks. I have seen others get fustrated and seems to be par for this hobby. But it seems very parculur that both where working and on week the AD went and a couple weekes later the AD went. Both are connected to surge potectors. Asl I only have a meter no scope to test with.
Thanks to all you can help be get these old girls back up and running.
