Hi vamvakar,
Congrats on the new tv. Try turning off "FILM MODE" in adjustments. Maybe it will help!? Don't know, but maybe. 
The menu can be accessed by pressing the menu button twice. Then RED + GO while the cursor is placed on the CONNECTIONS field. Then "Adjustments" and FILM MODE OFF...
Hope it will help. I think the TV becomes much better with FILM MODE OFF!!!
