My son accidentally sat on the remote, so we're not sure what was pushed. But now as soon as you turn on the TV the screen is blue and says NO SIGNAL at the top. Within roughly 3-5 seconds the TV turns itself back off.

TV is probably in the RGB mode. Since no computer is hooked up to the set it detects "No Signal" and will then shut off within seconds. To resolve you will need to attach a computer (laptop is easiest if you have one) to the TV RGB input. Turn on your TV and it should show what is on your computer screen. Then go to the input button on your TV and scroll to the input for the cable signal, or TV if no cable being used, and all should be good.
