I've had this DK Jr machine for about a month and it's worked fine, but yesterday we turned it on and the screen was all messed up. There is a distinct white fade across the top of the screen and there's a ripple effect going from left to right.

The machine was working earlier that morning, then my wife noticed that the marquee light was on but the screen was blank, so she unplugged it and plugged it back in and the wavy screen problem started. Nothing has been recently changed inside the machine and it hasn't been moved or bumped recently.

I know that the previous owner applied a cap kit relatively recently, but I don't know much else about the history of the machine.

Here's a video I recorded of the problem, the white fade across the top kind of looks like a glare in this video but it's definitely coming from the monitor. (sorry it's sideways, I don't take many videos with my phone and I didn't realize it was going to upload that way) http://www.youtube.com/watch?v=sV5S529Izr0
 
Check the B+ voltage
Isolate the power - if using a power strip get rid of it. Get the machine on it's on outlet.
