Actually, wrapping it tight, if in plastic, probably hurt your chances, as the warm moist house air would have condensed moisture inside the wrapping and TV.
A quick check of several of the brand name manufacturers shows allowable storage temps from -22 to +5F on the low end, to 113 to 158F on the high end. I know I have seen them shipped and stored around here down to -40F without apparent damage.
The key is to let it (and the remote) sit at room temp and exposed to circulating room temp air for at least 4 hours and preferably a full day, to let any frost melt and then totally dry out BEFORE plugging it in. I would then let it sit for at least a couple of hours to further dry the power supply (which will be on and warming once plugged in) before turning it on. If you have a small portable fan, I would direct that at the vent opening side (probably back) to help with evaporation of any moisture in there.
I imagine you will be fine, but just to be on the safe side I would be prepared with the remote (with new battery) to turn it right off if you see or hear anything odd when you turn it on, and I would not leave it on when out of the room for the first few hours, just to be on the safe side. Or plug it in through a surge protector plug strip with a circuit breaker in it.
