I'm going with no. Such failures do occur but you would be asking the same question whether it's that box or another thing like a PS3 so, no.
I'm a bit confused about why the confusion here. That is, most of the current electronics are now 5 year designs. This seems to be new to many folk but the lower prices we are enjoying is simply longevity was sacrificed on the alter of low prices.
So this tv has worked perfectly since I bought it a few years ago. I just got a mede8er md600x3d media player, and was playing a movie from my WD external hard drive, with an hdmi cable from the media player to the television. About half way through the first movie on the day I hooked the media player up, a horizontal gray line appeared across the top of the television screen. This line appeared on all inputs, even when I unplugged all devices. The line progressively worsened, and became hundreds of gray and black vertical lines, until now when it is basically a totally black screen, except for a small sliver at the top. I've tried a hard reset, but that did not work. Could an external device actually fry a television screen? I am really at a loss, please help.
