Sure wish we knew which brand and model of set it is, but it sounds like the tv is going into shutdown possibly caused by bad solder connections or a weak component on the circuit board. The only thing you can do yourself on this one is to disconnect the power cord from the wall for a few minutes and hope it clears out any confusion in the microprocessor. Otherwise, you need a service person to go in and check it with test equip. Good luck, Russmann.
Good thing the tv is under warranty, theres no magical fix for a problem like this. I would either return it to the store or call for service. If you atempt to do to much to fix it you might voide the warranty, and you should have to do anything to fix it as you said its 3 days old.
Sounds like something is getting hot causing voltage loss or drive pulse loss to the vertical IC. Maybe you have a bad solder joint. Try tapping the circuit board around the vertical section. A capacitor could be heating and opening up.

Also you might try using circuit cooler spray and make the problem show up.
