Does this come with any type of manufacturers warranty?
No. 90-day Woot warranty.
The one we purchased had to be returned due to what seemed like low rail voltage. There was an annoying clicking sound when using the menu, and occasionally the TV would simply go dark for one or two seconds.
It is a great TV for the money, when it works. You may have better luck than we did. Woot! customer service was really great when we did have a problem, so it may be worth the gamble.
does it get hbogo?
