And when you make the call, they should have you install latest firmware and factory reset then re-test for the issue. at that point the warranty kicks in.
As to refund, the maker didn't sell you the TV so refund demands go to the seller, not maker.
I bought a 65" led HDTV back in September. About 3-4 months ago while watching a hockey game I noticed while the screen was moving there were these dark areas all over the screen. The only way to describe it is I first thought it was dirt or dust so I tried to clean the tv. That's when I noticed that it's behind the screen. They appear to be verticals stripes of different sizes. Very hard to see unless using your peripheral vision. But once I noticed it I can't stop seeing it. They are present on all sources, xbox, blue ray, satellite. I have had the entire panel replaced under warranty and it is still the same except now I have this loud buzzing in my speakers(the least of my concerns at this point) but even the tech said he has seen this once before on an LG tv and what he thought the problem was was the spacing between the leds. Causing dark or dead zones in the screen. I am about to call lg back soon to demand that they either repair or replace the tv or refund me my money but wanted to try this forum to see if anybody has ever heard of this before?
