New guy with Asteroids questions!

[Toolguy]

Hello!

Thought I would join this group. I am a pinball guy but am going to
look at an Astroids Mini on Saturday.

I restore pins and do as much board work as I can, so I am familiar
with soldering and component, chip and header pin replacements.

My questions to the group are:

1) This mini powers and plays, BUT the ship shots are lines instead
of dots. Has anyone heard of this and what is the fix?

2) I have heard many times of a "CAP kit", I belevie for the
monitor. To me this probably is capacitors. Where can I get them, or
the best place I suppose really?

3) I know many pinball sites for parts, where do you all get parts
for arcade machines from online?

Of course if I get this machine, I will remove the board and check
solder joints, connectors and all that, but I just wanted to know if
this shot issue is a ROM chip, or possibly just a component.

Thanks a lot and I hope to learn more about video games now!

The fact that your game is in a small cabinet has no bearing.
Internally a video game is a video game if it is mounted inside a
shoebox or refrigerator.

Asteroid like other XY games have been designed to interact closely
with the operation of the monitor. There are pot adjustments on the
monitor but before you move the pots you need to confirm that the
problem is in the monitor.

While I have professionally repaired these monitors for many years I
have not seen this problem before (not to exclude that it could be the
monitor). The best and most reliable way to discern logic from monitor
problems is to take your logic to a working game and see if the
problem follows the board. If it doesn’t you are left with three
possibilities what is left in the cabinet: wiring connectors in a 30-
year-old game, the monitor, and the brick/ AR1 power supply.

There are many common and identifiable problem in XY games for me this
it not one of them. Therefore before you try to repair you need to
know what is bad. Return to the working game with your monitor and
keep swapping until the problem has followed the ONE thing that item
that is not original to the working game.

Good luck

After thinking about your problem I would suspect your logic to be the
problem if I were to guess. I process that I outlined before is tithe
process that I use with an unknown or familiar problem.
