Bought a Sony KDL60W605B from the sony outlet. According to the manual it's a LCD with LED backlight. Using it for a few hours and noticed a shadow I think screen burn on the side. It is unnoticeable on normal dark scenes but on light ones and white screens it is visible. I read that LCDs cannot get screen burn and am unsure what this is then. Have had a look around and everything says screen burn. I don't really want to send it back as it was a good deal. Will this go away or get worse? Anyway to fix this?
