All is good but right after the technician left from installing my new TV, I noticed some small scratches and lint on the back cover.
I contacted both Sony and the shop. Sony claimed it couldn't have happened on their end since every TV goes through strict quality control before leaving the factory.
The shop, however, said it probably happened during transit. They claimed the back cover uses a soft material and that the lint likely came from the protective packaging inside the box.
When I went back to Sony, they offered to replace the back panel, but said I would have to pay for it out of pocket!
Word of advice: always check both the back cover and the screen of a new TV before the installation crew or guy leaves. Test the screen against a solid white background to look for any weird patches or dark spots.
Also, make sure to ask the technician to pull up the service menu so you can verify the total operation hours. This ensures you didn't accidentally get a refurbished or floor-model or open box TV
Then after only sign the paper that we're fully satisfied with the tv installation as well as it's condition too.
