Congratulations and welcome! It sounds like the monitor video cable is loose and likely just needs pushed back in a little more. I would check both ends of it. So where it goes in the monitor and the other end going into the composite.
It’s all located in your backbox and the monitor swings out but you have a couple wooden locks on each top left and right corner you will need to loosen a little. This will allow you to unlock the monitor mounts and swing it towards you. Then just below that to the right is the computer.
Here are some pics.

Quoted from PinMonk:

It should be clear from the abortions that JJP engineered first that not just anyone can make a protector that works well. The CAD program, tooling, and everything else are nothing without specific know-how and experience. Cliffy has that in spades.
I checked with Cliffy today. The ones on the Dialed In made on the 30th that shipped from the factory with Cliffy-like protectors are actually real Cliffys. He wasn't sure when they were going to be on the Dialed In machines leaving the factory so he couldn't say anything until they showed up in the wild. I'm 100% thrilled that JJP is working with Cliffy now to ship their machines with his awesome protectors!
Credit where credit is due, JJP is the first manufacturer to come through and realize shipping with actual cliffys is the pro-customer way to go. I'm just surprised JJP isn't advertising the fact that Dialed In has them now. It's a real PLUS for them, IMO, and a post-purchase cost-savings for the customers who won't have to buy them.
BRAVO, JACK! It took a while, but you finally got this right! Keep it up!
