Horizontal Line Splits Color

[scottamurphy 0]

Have an RT. Wouldn't you know it the warranty expired 5 months ago.  There's a horizontal line on the middle of the screen.  the images and screens display fine. However, above the line all is in a blue/purple/gray tone. Below the line it's properly colored.  Took it to my MS store where I purchased it and was told it would cost $320 for a service call on it. Approximately 1/2 the cost of the unit!!Has anyone heard of this problem and/or have a solution?  I could open it replace something but I'd rather not sine it's a bit more intense than a laptop.

 

Thanks
