Question about Sony KP-57WS500 57" Rear Projection Television

1 Answer

Full screen has lighter colors on 8 inches on both sides.

8 to 9 inches of either side of screen has lighter colors than in the center of the screen. This is on both Digital or HD and on non-digital Bought the TV from Sears five years ago, just now got HD or Digital

    I have similar/same problem. Its like the entire screen is a shade darker than the Left & Right edges of the screen (about 8" in). Of course its only noticable when you switch to wide screen. Seems hard to believe all three guns have the exact same problem and are failing the exact same way.

I have a Toshiba 51h83. Everything works fine except there is an issue where the colors are slightly lighter on both the left and right sides of the screen.


this is normal with rear projection tv's its from long usage when the tv isnt always in full screen mode. you can sometimes fix this by replacing the bulb/ or the color board for the projector. also you can replace the screen as it seems like it may also be do to image burn in if it wasnt always in full screen mode. (did this for my uncles Mitsubishi projection tv)

let me know if that helps!

I have a philips HD rear projection TV 60 in. inside there are six adjustment knobs. Three are color the other three are for brightness contrast and hue. Which is which Left to right


If yours is a rear projection TV the adjustment knobs on the focus block inside are screen (red, green, blue) and focus (red, green, blue). The ones you are referring to as color are the screen controls and they adjust the intensity of the color from each tube. The other set adjust the focus of each color. They are also not intended to be adjusted by the user. Unless major components have been changed these controls should not need adjustment. That is why they are inside the TV.

How to center a screen?


Horizontal centering is performed in the service menu. Beware! You can mess up a lot of stuff in this menu.

Color is lighter in center of screen. It started as a small bat-man cape shaped area at top of screen and has moved down the center of the screen over the past week. About 5 inches in width and light blue...


sounds like the alignment in the color guns is off. this takes a professional to repair and usually isn't too terribly costly if it's just a realignment. check your local directory for large tv repair.

I have have this TV for almost 3 yrs..now have a shaded area on the left side


The dark side of the screen causes of the lamp alignment or prism glass alignment. This is critical you have to consult your LG technician to do this. But if you have any background o repair consult the service manual. Please careful not to touch the prism quarts so that you maintained the clarity of picture and brightness on the screen.
