You probably blew one or more fuses on the rectifier board (bottom cabinet). Are you getting any startup bongs at all?

Flaky lamp sockets and LEDs are a PAIN. However, you can clean inside them with a socket cleaning stick and solder them back together so you won't need to replace them. It's not a fun job but I can do an entire game in an hour or two usually. It would take at least that to put new ones in and it saves you the money of buying a ton of them. I typically solder the sides only and if I'm still having trouble I'll solder the wire to the center pin.

The post on the right side of the spinner should be a machine screw mounted from underneath with a nut on top or a machine screw mounted to a t-nut under the play field. If just a wood screw it will strip taking pop bumper hits and missed shots at the spinner.

Your spinner should be perpendicular to the playfield, or leaning very slightly forward from the top. Your spinner arms aren't square and it's off balance/leaning way too far forward. You're also missing the original Stern spinner which is superior to that repro. If you have the original, it will work better. If the original is beat up and you don't want to use it, sell it to me.

My QS has a star post in front of the left spinner and a mini post in front of the right which is what's depicted on the game flyer so I would assume that's the correct way. Also, make sure it's mounted through the playfield and not with a wood screw only.
