Our TV worked fine, and now it won't turn on, it just flashes a small red light on the power, if I hold the power in, it shuts off (the light) push power and light starts flashing, it's like it's in a sleep mode. But it won't turn on at all.

It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.
did you try new batteries in the remote? if the tv has buttons on the side and one of them being power di you try to push that? did you push tv power or cable power holding the buttons longer? those things might work.
these a couple things you can try to reset,if resetting dont work you will have a amp problem.Try pushing and holding down these 3 buttons s.speaker b and att and exit buttons for at least 3 sec or more.should reset.If not also try pushing and holding down mult speaker and exit and att buttons together for at least 3 or more seconds.if still shuts down you will have shorted transistors inside of unit.
I found a way around this problem. When this happens, don't use the remote.
Walk up to the TV, then HOLD DOWN the power button and while the lights are flashing, start pushing the menu button on the TV at the SAME TIME.
Then your screen will turn on. No idea why this works. Just stumbled on it while getting ********** that this TV, I had less than a month, suddely would not come on anymore. I was about to unplug the whole thing to take back to WalMart and just started pushing button combinations and found this worked.
same frustrating symptoms on brand new 42inch here! tv just turns itself off sometimes without warning or if changing to certain channels. leaves red light flashing for a while then red light goes away. any attempts with remote gives flashing green liht on tv. manual power off and on restarts tv but auto off again. found while manual power on keep changing channel on remote till stable picture appears. then use remote to shut down tv - solid red light indicates standby mode. then use remote to turn on again... till next time it happens. but what is technical fault??
