4 inch thick black vertical line down the middle of the screen

Same problem i am having a black horizontal line middle of the screen appears from no where..... just one and a half months old. this seems a common problem with samsung. then why they called themselves the world no one TV. Sony is the leader no doubt. what should i do? i am thinking to buy a sony rather than again using the Samsung ****

Hello JayZ,
Let me explain whats going on here. Your lite engine (inside the TV which shows the light) has a part called the lite tunnel. They use a special glue to put four rectangular glass together to make a small tunnel. This glue falls apart inside and cause a shadow. This can be fix by replacing the lite tunnel which cost a few dollars. or you can replace the entire lite engine which cost over $1000. This is covered by the manufacture because your set is still under warranty. Samsung would rather replace the lite tunnel because its cheaper for them. The problem with replacing the lite tunnel is that it takes a special trained tech to do that. If the part is not installed correctly you may end up with a tilt picture or top of the picture is mis aligned.

A month from purchase you shouldn't even bother yourself with this. Their problem.... give the shop/samsung a call. If you have no reason to suspect any cable problem, and a different input device(other than the DVD) doesn't affect it, don't waste time and get on the phone. Good luck
