First time poster here.
I've had a Royal Rumble in my collection for a few years now, with minimal issues. Yesterday, I opened up the backbox to check on a bulb not working. After putting everything back together, my display isn't coming on. I've looked this over 100 times and can't find anything that stands out as wrong.
I'm not an electronics guy, so I haven't tried anything super techy. I have though swapped out the ribbons and reseated all the other plugs to no avail. Can someone take a gander at my attached photos and see if anything looks out of the norm?
Before this happened, the display looked perfect, so it wasn't on its last legs or anything.
I'm at a complete loss.
PS. Yes, the display board is dusty.
PS2. Yes, I still have AA's on my CPU Board.
