Bit of an odd question for you, but is there any problems with water or liquids getting down into the TV compartment. I like all the counter space in the UN floor plan, but I worry about that TV getting wet! LOL
As JoeMazz said, there is a "lip" around the TV hole that is sealed down the counter top to prevent spills from getting into the electronics. I find this area useful to set small items during travel so they don't slid off into floor too.
I have also found after recalibrating the auto level system to my own tastes that the counter slopes towards the floor when floor is level. Spills should run into the floor if you have your floor leveled.
