Old Apple LaserWriter 300 Help!

Today my LW300 died or so it seems...I took it apart to replace the fuses on the power board and noticed the fuses looked fine. The capacitors all looked great as well.

It seems to do nothing when plugged in. No sound or activity (motor etc...) except the green LED by the "U" looking icon (the top one of the three LEDs) lights up for just a second and then turns off and the printer appears completely dead.

Anyone seen this before ? Thanks for any ideas
I've seen it before on the HP4L series which uses the same engine. This might sound strange, but it's a no cost repair. Take off any plastic on the board. Remove the solenoid assy. as well. Then preheat your oven to 375 degrees F. Get a cookie sheet, crumple up 4 aluminum foil balls. Put one in each corner of the board, component side up. Bake for 8 minutes and cool off. I fixed a couple of dead boards this way. What it does is reflow the solder that cracks and loses connectiivity. The board is no good anyway, so it's a no lose proposition. It might smell a bit, so if you're married, wait until the wife isn't around. She'll think your crazy anyway.
