Love the clear ramps

Can someone take some decent pictures of their boards for me and post them. I had my games all turned on the other day with some friends over to watch a movie, no one was playing, and suddenly Genesis just seemed to lock up, power down and power on and nothing changed. The lower right little board I noticed one blue wire loose, and yes I'm terrible at describing this, but it looks as though it should directly connect to a chip and that it doesn't. Anyway help is greatly appreciated.

I circled in red on this picture the area I was talking about, just stole the shot from google images, but yeah one wire is disconnected going to that chip.

Thanks for the advice and help. Greatly appreciated. Busy with work the next couple days but will check it out more closely on Sunday.

Perfect thank you
