That would be either faulty power supply or faulty power board on which the power supply is attached to. The power supply is attached to the power cord.

Hi,
Red light flashing on tv indicates that tv got some problem and shifted to protection mode to avoid further damage.
If Lamp light is flashing on tv then check lamp that would be dead or broke, replace lamp to solve tv problem.
If standby red light is flashing on tv then let me know how many times it is flashing after 3 seconds long pause to provide you helpful info.
Thanks.

Flashing red center light


With most flat panel TVs, the TV turn itself OFF when it has a fail electronic part and the red light starts flashing. They call this "Protection Mode". The flashing red light should be a error trouble code.
But, it's weird that everything is working and the red light is flashing. Since you just recently bought the TV, I would get it check out while it's still under warranty. Better safe, than sorry.
