One of my first responder test is to try a lamp on that outlet then swap the power cord with a known good cord.
As beyond this is considered non-user serviceable, you get estimates for repair. If you want to know what failed, be sure the repair tech knows you want that.
I bought my Samsung 59" Television back on Feb 9th 2012 and yesterday Oct 12th 2015 it just stopped working. It does not turn on at all, there are no signs of life. No lights blinking, no solid light, nothing happens. I tried unplugging, plugging it back...nothing happens.
Does anyone have any insight on this issue?
