Year-old Samsung 50" Plasma - No Power

[YamahaFreak]

My friends found a Samsung PN51F4500A(FXZA) 50-inch plasma TV recently, and I have been tasked with the repair attempt. It was built in September of 2013, so just barely a year old. When I plug it in, the red standby LED turns on. If I press the POWER button (on the remote or on the set) the standby LED goes out...and nothing else happens. It's like the set was unplugged. There is no evidence of physical damage, screen doesn't appear to be cracked, everything inside looks good, nothing burnt/fried, etc. No strange sounds...in fact, no noise at all. There is no info online that I could find about this model having issues. Apparently it's last year's entry-level Samsung plasma TV. No 3D or smart functions.
