My 57" sony has a bout 20-25 thin red lines in the shape of an hourglass (half circle down, half circle up) that become ver apparent when the screen fades to black/ darker scenes. I have turned up the brightness quite a bit to compensate but now all i have is terrible contrast!! Any advice is appreciated. Kind regards, Blake
There's a lot of talk in the internet that the pots in the front of the tv will take these (horizontal?) lines out . i have the kp-57hw40, and there is a web site with pictures on making the adjustment. i believe the bottom 3 pots are blue, green, red going from left to right. mark the pots first so you know where you started, and they say it takes just a hair adjustment counter clockwise to remove the lines. Only go to the point the lines disappear. web site shows how to get front cover off via two screws hidden in bottom and then take off the cardboard cover to get at pots. Not to be smart, but don't be careless, keep hands out since there are high voltage circuits just inside there. . . .
I had the same with my tv and i removed the front speaker grill and the carboard cover. there are 6 screws. the ones that need adjusting are on the bottom. turn them very slightly until they go away.

We have the same problem and live in a town where there are no television repair persons. So we just gave up and bought a 50" Samsung Plasma at best buy. Sure is nice watching a tv with no lines in screen. We bought this television new in Spring 2004 for $2500.00. Very disappointed with Sony will stay away from their products.
