Bringing Up An Asteroids Deluxe Cabinet

[SNESNESCUBE64 | 540]

Well the time has come to work in my first vector. I picked this cabinet up from a KLOV member a little while back and was going to wait to restore it until I moved due to how heavy this cabinet is. However, moving is being pushed back several months so screw it! I brought it home yesterday.

First thing I did was validate power. I shotgunned the 2n3055 since I have those on hand (using up the rest of my thermal paste). From there I checked the ripple on the 5V rail. I measured some .4V of AC ripple so I replaced the big blue, after doing such it was good. From there it was testing the game board. To my suprise it booted up! Vectors are a little shakey but I've read that it could be because of the gain pots, those are on order.

With the game board outputting known good signals, it was finally time to mess with the monitor. This was my first time working on a G05-802. I figured it wouldn't be too terrible, it was described to me as "the baby mode of monitors". F700 was missing from the deflection board so I assumed the worst that one or both of the deflection transistors was shorted out. Testing it from the connector, I measured a dead short between the collector and emitter pins on the connector. Pulling it, someone had made a goof by swapping places of the 2n3716 and 2n3792. The 2n3716 tested bad, but I ended up swapping the pair (putting them in the correct places). Also replaced fuse F700 with the specified 2A fast blow fuse. This solved that issue, however I had another issue: brightness was cranked up and the adjustment was unresponsive. It is probably responsible for the burn spot on the monitor.

This ended up being a simple fix, I believe it was C504, that cap had actually tested bad. While I was there, I replaced all the other caps (except for the 6800uF input filters because I didn't have them on hand). I also reflowed the solder on all of the connectors due to a handful of cold solder joints being present. After that, contrast and brightness were fully adjustable.

Right now the game is playable but like I mentioned earlier, the vectors are a little shakey. I am still looking into that. I also have recap the HV cage on the monitor. Hopefully I'll make some progress this week. Overall this cabinet is in good shape and won't need a ton.

I finished up all the work I wanted to do for now and moved it into the row. I need to do cosmetics but that needs to wait as it isn't very easy to do that kind of work in the basement. I'm very happy with how it turned out.

Cool thread!  I'm no expert, but I've brought a couple machines back to life.  Like learning a whole new thing every time.  Thanks for sharing your steps here.  It may help me in the future as I own the cocktail version.

Funny enough I have a table too. It's currently missing the monitor and control panels, so it's just a waiting game.

 

I also write repair logs if that helps ya. I am really behind in writing new ones but should be soon.

Amazing!  I'm just a hobby-type guy, but I've done more in the past 20 or so years than I thought I would to repair consoles and arcade machines.

I will certainly be checking out your repair logs.  I may hit you with a question once I get into my next binge of trying to fix things.
