LG TV will not turn on

[hayhay2223]

My LG tv just started doing this last night, I will press the power button and it's turns it self right back off before the tv can even pop up with it's logo . . I do not know what to do. I've unplugged things left it for a bit tried to make sure everything was tight and secure. Anyone know what I need to do or what causes this to happen?

Thank you to everyone for their time.

First guess would be power supply problem in TV.
