Hi guys, I just bought a 32" R72BD and am mostly very happy with it (it has the nicer A panel), however I've noticed that on big blocks of bright colours, whites, sky blues etc, I can see faint black lines running down the screen - about 5 of them at regular horizontal intervals. They aren't sharp or associated with certain pixels, but seem like the screen is just less bright in the affected areas. It is unnoticable usually, but when you get a block of something light, they are visible. Is this just a normal by-product of the panel construction? e.g. is it maybe made of 5 pieces stuck together which causes issues with the backlight? or is this something I should be more concerned about? As a secondary issue, how do you actually switch this TV off? Pressing the button on the front seems to have the exact same effect as pressing standby on the remote, it can still be woken up by changing channel etc, the only way I've found to turn it off completely is at the plug :/ is this normal?
