So while I've seen it on way too many LCD panels the life span is affected by temperature, humidity and more so to flat out say it will last without issue for 5 years is a stretch now that Pb has been removed from solder.
What is this? Pb? Yes, Pb.

So this can rankle folk that are expecting more.
I apologise in advance if this subject has been discussed before. After about four and a half years my Samsung LED 24"tv developed a dark patch over about a quarter of the screen at the bottom centre. I was advised that it was not repairable cost effectively. I am old enough to still think that TVs should last more then four and a half years and I took it up with Samsung. They referred me to their local repair centre who immediately told me that this was a common fault with flat screens and confirmed the point about cost effectiveness. I put this to Samsung and their response was 'this is not correct information as there are no manufacturing defects .with any Samsung products this moment in time'. I wonder if this correct and would appreciate knowing how many other Samsung users have experienced a similar problem. With thanks in anticipation.
