Hi, remeber me?I consulted with you a few days ago about the ugly DSE on my new KD55XD7005 

https://community.sony.co.uk/t5/android-tv/kd55xd7005-dirty-screen-effect/m-p/2286108/highlight/true...

I decided I could not stand it.

The worst thing was a big 

ugly black spot in the middle of the screen that is visable during movies.

here is a good example:

The store replaced the product eventually, 
But guess what? The new set has came with the same ugly stain and now there is one big ugly  light leakage ..

I feel desperate....
