Hi, I turned my computer on yesterday to find a thin vertical black line (maybe 7-8 pixels in length). I thought some program had crashed so I rebooted and noticed the line was still there on the POST screen. I rubbed it a bit and it turned into a green cluster of pixels, which has now grown even more (picture attached). I tried several stuck pixel fixing programs to no avail. I also tried to massage it and that failed too. Also, I can see the same spot when the screen is off (laptop off), as in when looking at the screen from a certain angle you can see the cluster of messed up pixels. Any clues?
I lost the laptop box/papers but I still have the receipt, and its been under a year since I purchased it so I think its still under warranty in case I need to send it (Best Buy).
It's a Samsung R540
P.S It's kind of weird because the pixels are semi-transparent. I can see whatever is underneath them, just tinted green. It's not like a permanent 100% opaque spot, so I dont think its the transistors that are damaged but a glass layer or something?
