My son (18 months old) grabbed the remote and got into the service menu somehow and screwed it up pretty majorly. Seriously that happened.

HVFlip was enabled. It was booting with a Frame TV boot image (and this is a Q6 75 inch), Wifi wasn't working. Now there is a small box that is a red/pink color with green text that displays some sort of numeric debug value (0.00 most of the time, except on boot it can jump around).
I've fixed everything except the 0.00 debug text.
Anyone seen this before? Any suggestions? I don't have the TV in front of me, otherwise I'd post a pic.
Any help is super appreciated!
