I recently bought a LG 26LE5300. I love it so far but I have noticed that it won't stay in standby when turned off. when the power button is pressed, the display turns off and goes in standby but about 20 seconds afterward, the tv turns on by itself. it stays on with the LG cube no signal screen. I have also tried disconnecting all inputs and get the same results.

Defective power supply, return to service center.
just to make sure, by power supply do you mean the power brick that the tv uses or is it something internal on the tv?
i rather not have to go through the whole shipping processes if possible. I bought the tv used.
