Macintosh Plus screen is blank

Hey guys. I just picked up a Macintosh Plus off craigslist, along with an SE-20 (I believe that's the name) SCSI hard drive. I plugged it all in and turned it on, hard drive first, then the computer. The computer did it's little "ping" dealio when I turned it on, and the hard drive screamed what I can only guess is reading the operating system, then stops, which I would assume means it booted. I'm guessing this is a completely working system, minus the lemon of a monitor.

Basically, I want to ask the guys who love these machines: Any tips for taking it apart to check on it? Is this a known issue with a known resolution?

PS. I lol'd when I saw the keyboard connector.
