Can you turn off the blue backlight? (Paleo world says no blue lights at night, you know...)

Not that I have found. It's not that bright so have a thin cloth to cover it up and your sound won't be compromised

It doesn't appear to be very blue. It seems like the lower brightness settings have very little to no blue, and blue increases a little bit as you raise the brightness settings. I know the blue thats found in computer screens disrupts my sleep, and I haven't found that to be the case when I use this light (even when used as a night light). The higher settings, I've found, do give you energy similar to sunlight...Tried out the alarm this morning, it works like a charm

I really can't help you with THAT one....my child never uses under blacklight conditions. Sorry.

You can choose to turn it off or leave it on. The backlight has 3 settings: Active, inactive and standby. Each of the 3 settings has 30 backlight micro adjustments.

There are two tiny blue indicator lights that cannot be turned off when the system is on, but if you face them away from you, they don't cast any light. There is a white downward light that can be turned on and off.

When I turn off my XBOOM speaker the blue light goes off. The light should not stay on if you turn the switch to off.

There's a "clean display" button that will clear most of the icons (leaves current and desired temps). Also, the blue backlight can be set to always on or timed out. After some testing on my touchscreen...most of this info is always on but you can't see it very well when the backlight times out.

thats actually the backlite on the screen - if it can be turned off the user manual should tell you how --

The "night light" feature can be turned off, but it still shines a lot of light out the little holes in the purple part, and all of the buttons are lit up all of the time. I found this really annoying. I taped black tape over the purple part, but still have to hide it behind books, etc., to hide the bright blue glow from all the buttons.

No, but I believe you have to change the initial setting to turn off the back light for the clock

There is a cog looking button (sun to everyone else i suppose ha) that you press once for a low light setting and the second for full illumination. It works wonderfully and stays lit until you're inactive a certain amount of time -- though I've never turning off prematurely.

EJH, No, the light only works in the realm of white light. Apparently blue light has some untested side effects.

There is no backlight on mine. If they add one to later models let's hope they edit the description to reflect that....

Yes, you can turn it off. Product literature also says it has a "learning mode" if you turn the light on within a few seconds of entering the sensing zone, it will learn that you want it on in partial or even full light.

The light stays on all night. It's just very dim. Then when it senses motion it brightens. I don't know if its possible to turn it completely off.

Could be TV is in "ECO" Mode. Also, Energy Savings might be on. This setting adjusts brightness levels automatically. Settings are independent for each mode...Standard, Dynamic, Natural, Movie. Try turning off ECO and turning off Energy Savings. Go to Menu, then System, then Eco Solution, turn off Energy Savings and Eco Sensor.Try these settings:In Menu....Picture...Backlight 20, Contrast 100, Brightness 45, Sharp 45.Hope this helps. If not, I would call for service.Robert

I have a brand new Sony KDL-37W5500 that has the same problem: backlight "whine" when the screen is predominantly dark. I have tried all possible backlight levels and the problem persists on all of them (but setting 2 minimizes it). When I have the volume low at night this whine cuts through and is VERY noticeable.I have emailed Sony customer support about it - if it can't be fixed I will look elsewhere for a TV...
