My Samsung died today - had it for almost 2 years. The unit just won't power on anymore.
After leaving it unplugged for awhile, then plugging it back in, the power light does come on for a split second, then goes off again. Will try out the warranty center, but, given that I bought it on ebay almost 2 years ago, it looks like the money I "saved" on this by not getting cable is now going to be going to another hd tuner unit. I've been out of the market for so long - I'm not sure what they sell if anything anymore..
