star trek vector

my game shows color dots in all the grafix places
Montor is fine in another machine
Power suplly working and correct voltages
Have you tested other boardsets in that same cabinet or those boards in another cabinet?

Sounds like he tested the MONITOR in another cabinet...

The description of the problem is vague.

Are you saying the LINES are missing, or that the points where the lines come together have bright dots there?

A picture would make my guesswork descriptions useless...
 
It is almost certainly the Timing/Control pair. I have a spare Timing/Control pair in my parts pile that does the exact same thing....
 
Could it be the interconnect cable between the boards. I found some broken pins on mine. I am using some trace wire to complete the connection for now. But I need to find another connector cable.
 
Thats the kind of info that should be shared at the begining of a thread. LOL Yes you should either replace the broken pins or find a cable. It will be easier to replace the pins though.

I am using trace wire in place of the pins so all the connections are there. In the future I will be looking to replace the cable.

The timing board has two adjustment pots on it, what do they do?

Besides the speech problem I have, when I play the game I notice the score and the ships on the radar screen are doubled. Sometimes I get fooled and think there are two ships I have to fight, when its only one. Some ships on the radar show up fine, but some will be two images, slightly overlapped. And the score is the same, one number slightly overlapes the other. If you tried to draw a picture and then make it look 3D by drawing the same picture slighty off center under the first picture. I attached a photo of what the score looks like, and like I said the klingon ships on the radar screen has this same effect.

This may be easy.

Are the doubled images the same color, or different.

If they're different colors, then your convergence is off. I think the score and those pink triangles for the klingons are made from the red and blue traces.
You can go through and perform a color setup for the monitor, but Star Trek doesn't have good test screens for that.

There is a trick with either the service or the reset switch where you can get the screen to freeze. I recall using the screen with the white STAR TREK logo to aid in converging the beams on the screen.

The convergence in that upper left corner is more important to gameplay than having it dead-on in the center of the screen.

Good luck-

I would say your right about my problem, so how do I set convergence? Remeber I have the Asteroids Conversion setup.
 
I found this video, is this what I need to do?

That's a very good demonstration video.
To be honest, I've never used the correction strips. I've gotten pretty good results with the static convergence (at the center) of the screen using the purity rings and dynamic convergence (at the edges) with tilting the yoke using rubber wedges.

Several monitors I have use the little correction strips, but I don't know where to get them. Now if only there were a cheap vector pattern generator to produce those screens for a G08...

I find out that monitor did indeed have rubber wedges, that fell out. I was researching about doing convergence today, and found a photo that had the rubber wedges, and I remebered picking one off the ground when I bought the game, not knowing what they were for, well now I do. So now I need to locate some more rubber wedges. I do see the marks on the CRT where the wedges were located.

Anybody out there have any for sale?
