Strange Partial Image Flip on TCL LE55FHDF3300Z

Strange Partial Image Flip on TCL LE55FHDF3300Z Can't Post

The pictures should help explain the problem I am having with a newly-acquired 55" LED LCD HDTV (made circa 2012). All functions that I've tried seem to work, except the second 1/6 of the screen (going from left to right) is flipped around the vertical axis. Furthermore, within the flipped slice, the vertical columns of pixels or subpixels are not flipped together, resulting in a pixelated-looking image.

The TV turns on fine, brightness is good, it seems to be in very good physical condition. This problem seems like it must come from somewhere in the video processing chain, its connection to the LCD panel, or the LCD panel itself. With the description and pictures, can anyone suggest what steps to take next, or even better, narrow down where the problem could be occurring? I am ready to check connections and to look for bulged capacitors, but I thought I'd get some second opinions before I opened it up.

Good example, picture taken at an angle:

Simple example, note how it looks blurrier on the flipped portion:

Thanks for any advice.
