I have a Samsung 48inch hdtv smartcurved 2-3 months old

Thank you for the reply. So, just to make sure I understand- it's not the outer screen that's cracked, but just underneath that part of the screen- the inner picture is distorted? If so, this is a panel failure- meaning a compromised part of the liquid crystal underneath the screen. This unfortunately requires replacement of the entire screen of the TV to fix it- there's nothing that can be done besides that. Let me explain though, ANY company that builds an sells a device with an LED/LCD display, will not cover this type of failure as it's what's known as a "pressure spot"- meaning some external pressure (be it direct, or from expansion/contraction due to temperature extremes) caused the spot on the screen to appear. It's not something generally within normal occurrence and Samsung will try to push blame onto the end-user (YOU). If you're 100% certain no outside force could have caused this, then I would prepare to contact Samsung and VERY diligently explain the situation stressing that this spot appears on it's own gradually, and was not a sudden occurrence- and nothing that happened from any outside force, pressure, handling, etc. That is your only hopes in having this fixed, as in every case I've seen, the manufacturer will try to not cover the problem. I wish I had better news on this one but you'll need to call Samsung directly and try to convince them that the spot was not caused by you.
