LG 32LG30 doesn't come on when plugged on.

[Kar3Em]

My mom got an lg 32lg30 tv from a friend who said he put it on after having it for a little while and that it simply came off one day and didn't power on, while still being relatively new. My friend said it could be the power supply but I don't wanna try something like this without knowing what exactly is going on. Any advice?

Check the voltage of the power supply with a voltmeter and see if its working would be my first step esp sine it sounds like its an external power supply.
If it's internal and relatively new, I would call for Warranty service.
