ESA 42' plasma turned off on it's own and won't...

Question

I was watching my ESA 42' plasma last night and all of a sudden the tv turned off. I tried to use my remote to turn it back on but nothing happened. The remote wouldn't work and I tried to unplug it and replug it and nothing happened again. There is a reset button the side and I tried that also. The tv seemed alittle hot. I only had it on from 8:30 p.m. to 10:25 p.m. and I hardly even turn it on. Did it just need to cool off and maybe it will work when I get home from work. What do you think ??
