Hi all i bought a UE40ES6300 from Richer Sounds store in Bath and i am very disappointed with the picture which looks washed out and lacks detail on HD and is also poor on SD broadcasts. Im just wondering if i can return the set as it is less than 4 days old. I have looked on Richer Sounds web site and it says Goods, other than faulty goods, may be returned within 7 working days of the date of receipt by you of the goods. does this mean items i have opened and used?
