This is what my 5 years old 37" Westinghouse 1080P LCD looks like right now, those marking are getting worst and worst, they don't show on very bright and solid red, green, or blue, only in grayish background. color temperature is also way off by now, white screen has yellow tint and patches on edges, is this LCD dying or about to died soon? what do you do with a big screen like this? Been using it as my PC monitor all these years and only started to developed these marks lately.
