I am relatively new to HDTVs. Recently I bought a lc60sq15u Sharp. I noticed that in watching movies, shows like Downtown Abbey on Apple TV, etc., that there is a backlight bleed through to what I am watching - which is really noticeable when the part of the picture should be dark - you can see that the backlight is making the picture lighter in that area.
I am now on my second lc60sq15u after returning the first one. Same exact problem. I have played with the settings and can mitigate the problem by either turning the backlight down a lot, or turning on the light sensor.
when I turn on the TV as it boots up, I can see areas on the left and right (mid-left/mid-right) that has light showing though the rest of the screen is really dark. As the TV boots up, or as I switch inputs, I can clearly see these light patches as the TV adjusts. Problem is these lighter areas are still there when the picture is playing too. When I turn on the TV it is totally black, but I guess as the LED starts up then you can see these patches.
If I turn the light sensor to "off" then the patches are worse (the screen is brighter - but the backlight problem is too). If I turn the sensor to "on" then these area dim somewhat - as does the brightness of the TV screen. I can manually make them somewhat dimmer (they never really go away - just become less notable) by reducing the backlight setting if my light sensor is off.
Has anyone else noticed this with this class of Sharp TV? Is this normal at all for LED TVs? I really don't want to have to take this one back as overall I like it - except for this bleed thru light problem. I have Sharp sound bar as well so I am involved with Sharp products now but still debating as to whether I am committed or not.
