Vertical lines of dots and colored blinking squares across the screen

Our new (Christmas present) Xbox 360 is displaying vertical lines of dots and multi-colored blinking squares.  It happens on every game, and within 10 minutes of startup.  Games don't freeze up or seem affected at all by the dots.  The position and number of lines changes, but mostly seems to be 2 or 3 lines of dots evenly spaced vertically, then a line of blinking squares, then 2 or 3 more vertical lines of dots.  We are using the same t.v. that has been used for over a year with our other consoles, and do not have any display issues with the other systems. 

I have some pics, but I don't know how to include them in this post.  :(

Any help or advice will be much appreciated!

Are you on HDMI? If so, try a different cable or a different input on the TV. I've had flakey HDMI do that.

 

If you are not on HDMI, the console's dead out of the box. Exchange it at your retailer.

Did this solve your problem?

I've had a similar problem with my first Xbox, except mine had a faulty overheating problem were the screen was horribly colored with vertical and checkered squares. It happened to be that the soldering melted on the motherboard and Microsoft wanted to charge a whopping $150 (6 years ago). Since your console is new you can try to take it back to the retailer but they will most likely tell you to call Microsoft. Hopefully they will replace/fix it for free.
