My CC Princess is doing most of this same stuff except mine also doesn't score. No lights on the backglass either (except GI), no game select, although it does add players on the player mech when you hit the coin button. It does seem to somewhat play in that it will take a couple balls and reset the pins but that's about it. I'm suspicious of a voltage issue somewhere. I'll let you know if I make any progress on mine. It was working well and then suddenly went south at a party.

Can you take a picture of the inside of your backbox for me? Some of my relay and switch labels are missing. I'd really appreciate it.

I appear to have my lights back. I had a fuse that checked ok out of the game but had a barely noticeable break. When it was under load the break would separate. So, I can manual select a game but get nothing with the button or the game selector relay (if I manually engage the relay). No voltage at the game selector button. I just got done tracing wires around to the game selector unit - seems ok. Also, when my score motor engages, it spins more than once - up to 4 times before stopping. I'm taking a break!

Your game is a lot cleaner than mine!!
