Samsung UN55EH6000F Issues

[vortalexfan]

Hello, I was working on a Samsung 55" LED LCD TV for someone that the Mainboard had died on it due to a lightning strike and I got a used one from ebay and when I installed the replacement board into the TV and turned it on the TV came on but the picture was upside down for some reason and I'm pretty sure its an issue with the settings but I'm not finding that setting anywhere in the menus for the TV, not even the service menu, does anyone here have any idea how to flip an upside down screen right side up again on an LED LCD TV? Google was no help.
