Why are display colors right half different from left half?

With my Thrive in landscape position the left and right halves of the display have different colors / tints. I have done a reset to factory data and have opened unit and reset the display ribbon cable at the LCD. I took some screen shots and the issue does not appears when viewed on another tablet. I have some photos but don't see a way to attach. The right half appears to have some colors over driven with the camera on the left side. This phenomenom always shows on the end opposite the camera as the tablet is rotated through 360°.
