Upright Atari Asteroids Arcade with No Video

[grahamreitz]

Hello,

 

I recently inherited an Upright Asteroids arcade game. The kind found in the old arcades. The game appears to operate but there is no video output.

 

I've been reading around and it seems one of the first things is to replace all (or most?) of the electrolytic capacitors. I was able to find the Real Bob Roberts site that offers re-cap kits. There are several cap kits (http://www.therealbobroberts.net/caps.html) including one specifically for the Asteroids game.

 

Questions:

 

1) Is the Asteroids re-cap kit all the I will need?

 

2) Is anyone familiar with this particular video issue?

 

I'm an embedded engineer and quite familiar with circuits and etc. Although, I am entirely unfamiliar with the likely failure modes of this machine, and would be grateful for insight from folks experienced repairing the Asteroids arcade game.

 

The model number is 215 XX.

 

Kindly,

Graham

I would get a service manual first! That way you get familar with the hardware and how it works.

 

Also, try this site:

You should sign up for the KLOV forums and ask about it there in the Technical - Videogames - General Repair And Help subforum. They specialize in arcade machines over there.

A couple of guys around here are pretty deep into arcade game knowledge, too. Somebody may chime in with some suggestions.

Did you check the Flyback Transformer?

Yes, but asking his question over there in addition to here will greatly increase his chances of finding a solution.

+1 for Bob Roberts!

 

If the game plays blind, I'd suspect bad monitor components, but the video stage is on the large CPU board too IIRC. You see neck glow on the tube or hear the familiar flush of a CRT booting up? Either way, the link above should be of major help…

if you're looking for arcade monitor tips, you should check out Randy Fromm's video series on youtube. He goes through the entire basic theory of operation of CRT's and some troubleshooting tips for various issues.

 

edit: or he did. for some reason he pulled down his CRT videos.

Is the game playing blind? Can you get any display in Test Mode? Which version of the monitor do you have, Electrohome or Wells Gardner?

We can talk if over Graham, I have an Asteroids and Asteroids deluxe uprights, so I am a little familiar with these monitors
