If you haven't played The Last Of Us, I would highly recommend it. I would say in my opinion it is the best game I've ever played, and I've been gaming for thirty years. It has the +mode so the weapons and skills you've upgraded are carried over on your next playthrough, which is obviously harder but you also have better gear and that in itself is addictive and pushes you to play again.
Yes it was me with the DSE issues, I have a dark smudge on the bottom right of my screen. I have taken photos which you have seen, and sent them to the repair place that was recommended to me by Panasonic. They are sending an engineer to look at it in person, at my convenience, but I work away a lot and haven't been able to find a time suitable for them/me. Sometimes I don't notice it to be honest, and then other times it irritates me, but they know about it and I have four years left on my guarantee so I'm not going to stress over it. I've seen a lot on people on here get very frustrated - and rightly so - with Panasonic and their policies, so I'm not expecting to be treated any better than what I've witnessed here, and I didn't buy mine from John Lewis so I don't have that advantage. It will get sorted at some point. Don't think I'll be buying a Panasonic again though.
