My HD52359TV won't power on. When I press the power button it stays on for about 8 seconds, sounds like it's turning on, then turns off & picture never comes up. It was working fine yesterday & I turned it off, left for a little bit & when I returned the power issue started.
Could anything have spilled inside? Since you weren't home you can't be sure. unplug set, get a handheld hairdryer and blow thru the tv side vents for a half hour on medium. Move the dryer around all vent locations. Plug tv back in when done and let me know.

Trying installing a new power supply. This is the main problem with tv's with the issue. But if you just bought it I would try to get my money back from where I bought it from. Installing a power supply for a tv is not that hard at all.
