Thanks Leon. This must be my lucky day

I should run down and lay a hundred on the Pass Line at the Nugget

Started to really get worried when under bright light I could see no burnt components. That should be good news. But I could not identify what caused the "phttt" when plugged in yesterday.
Figured I'd check the pic. Did not look properly seated. Pulled it out re-seated it, plugged it in....and.....I HAVE BLINKING LIGHTS

So lucky not to have fried something.
