Flashing, choppy picture when source is connected

And flashing lines on the screen when no source is detected.

This one turned out to be an easy fix. I suspected typical bad voltage regulators but didn't find any that measured out of spec. After the regulators checked out, I started checking voltages from the PSU. As I stuck my probe in to check the 5V leg of the PSU, I bumped the LVDS cable and the picture cleared right up. I wiggled the cable and the picture cut in and out as I wiggled. I unplugged the cable from the T-Con and used a folded piece of paper in the female connector on the board and on the pins of the male connector on the cable to remove any dirt or oxidation. I plugged it back in and was unable to get the picture to cut out when I wiggled the cable.
