A few years ago I attempted a restoration of a Cocktail Defender cabinet and failed miserably. I basically just threw a bunch of money at it and had no clue what I was doing. I still have the cabinet and lately I've been wondering what I should do with it. I might even consider selling the cabinet if any one has any interest, but for now I think I'm going to try and troubleshoot it.
Usually, when I try powering it on 4 led lights come on the rom board and stay on until I turn it off. Every now I can turn it on and the 4 led light will flash for a second followed by the startup sound with no picture on the screen. One time after powering it on the screen cycled through red carpet over and over again. I think the problem might be with the power supply or the main board. I have a switching power supply that I bought from Bob Roberts a long time ago, but I'm not sure how to install it.
I could really use some advice since I still don't know what I'm doing exactly.

First off you need to pull the manual down.

Once you get it you will know more about what its trying to tell you.
Second I would think about getting a rebuild kit for the power supply. Working or not it will be needing it. Check for a rebuild kit fort the sound pcb as well and get the cap kit on order for the monitor.

Alright, I installed the switching power supply and I get the startup sound every time now. The 4 led flash supposedly means it passed the rom/ram check. Right now I'm using the monitor hookup to power the switcher, so I have no idea if anything is showing on the screen or not. I check to see if it could play blind, but didn't have any luck. I also noticed that the second LED light on the PS was out; I guess that's why I was having problems.
I'm not sure how to properly feed power to the switcher and the monitor at the same time just yet. Once I figure out how to do that I can start troubleshooting what I believe to be a problem with the main board; the same problem that caused the never ending rug pattern. I read that it might be caused by a problem with the DRAM, but since I passed the rom/ram check I'm not so sure.
The monitor I have has apparently been capped, so I don't think I need to worry about it. Rebuilding the power supply sounds like a good idea; it isn't dangerous though is it?
One last question: The switching PS gives off a sort-of burning metal smell similar to a hot soldering iron; should I be concerned?

And, yes, be concerned about any weird smells.

I sent you a PM, but thought I'd post in this thread as well. If I remember right I sold you a pair of the cocktail joysticks. I recently picked up a Joust cocktail and need one joystick for it. If you didn't use both of the sticks I'd love to buy one back. It turns out the sticks are really hard to find.
Thanks!
