Is this tv really having backlight Local Dimming because the screen is not back (it's lighted) when watching at night and image gets black?!

The TV is edge lit with LEDs. It claims to do local dimming, but with edge lit TVs, the local dimming is very coarse (unlike full array backlights, which can dim smaller sections of the screen more effectively). In my experience with the TV, it basically dims the entire screen if it is mostly black or dark. For example, during the credits of a movie where the screen is mostly black with a little white text, the entire screen would suddenly dim. In a completely dark room the screen would not look completely black like a plasma or OLED, though. It just drops the backlight level to make the blacks look darker. I actually didn't really care for how it was implemented on this TV, though; I found the sudden drop in backlight level while watching TV jarring.

I've had mine for almost six months and it happened couple of times. I've noticed that it never happens when I watch a DVD or Blu-Ray disk, or when I am streaming something either from Internet or my media server. It only happened when I was watching cable using my Comcast digital cable box. When it happens it goes black and comes quickly right back. Before it comes back it shows for a split second a sign that it is establishing HDMI connection. I was wondering if it has something to do with the cable box, but it is so rare that it is difficult to identify a pattern.

No, the display is not backlit. It seemed to me that I read someplace that there was the possibility of back lighting, but it must have been wishful thinking.

We just received out Samsung 32 inch TV and after reading these posts turned the back light 8. It worked for awhile but I think there is something wrong with these TVS. Anyone have anything else to try

That is something that would most likely be in your TV's menu. Try finding the menu button on your TV remote, then find the picture setting. There should be an option to decrease brightness in there.

If your picture is dim then a new lamp should make it like new again. It is doubtful anything other than a degraded lamp would cause a dim picture. I wouldn't expect to get a refund if the lamp works. I bought one but really couldn't tell a difference. I don't know if the TV just didn't need a new lamp or that the off brand lamp isn't as bright as an OEM lamp. Personally, I'd stick with OEM Sony parts. They cost more though.

Nope never noticed any thing like that. Check your TV settings, in the burn in protection settings there is a setting called pixel shift, its turned on by default it moves the picture a small amount every couple of minuets to protect from burn in's. I suppose your settings could be off the default settings are pixel shift: on, Horizontal: 4, vertical: 4, time: 4 min. This probably your problem you could try turning it off at your own risk as you may have a higher chance of burn in's and most likely image retention. You payed good money though if that doesn't fix it return it! Samsung is know for problematic plasma tv's. I wish you the best! Nope never noticed any thing like that.

Hi! No matter what angle or what dimmer setting - I can't read the display. It seems that the back lighting is too bright and everything is lit. Instead of 8:30 like the picture on the left here says... my clock reads 8:88

We've had the ld350 for a couple weeks and it does the same thing. It makes an annoying buzz when we turn the backlight down lower than 75-80. Other than that we are liking the tv and hate the thought of having to return it, but this is very irritating with the sound low at night in the bedroom. Also, afraid it may get worse.

Its really bright if you put it in the vivid preset. To tell you the truth when i watch tv i cant tell if its a plasma or an led...the only thing that gives it away is at night time when its really quiet, i can hear a faint humming coming from the tv. Other than that, i believe this is one of the best tvs on the market today!

I made setting adjustments, updated the firmware and have since watched scenes with dark backgrounds and it seems to have gone away? Don't know why for sure but so far, so good. Thought the same. Perhaps it is a HDMI cable issue but was seeing it both on tv broadcasts as well as DVD so felt it must have been related to some sort of setting? Don't think both of my HDMI cables would have been bad! Thanks.

Take televisioninfo's reviews for whatever they are worth. They have weird way of measuring. e.g. They measure the black level with Local DImming off. What is the point of that measurement. If someone buys a Local Dimming set and watches programming with LD off ... then he/she might as well have saved some money and bought a non-LD set.

Most of the time if lamp is getting bad you notice slowly the picture getting dimmer and at this time adjusting the brightness has minimal effect. If you notice this pattern then yes change the bulb. Normally the TV do not go black abruptly.

The picture and brightess seem excellent to me. In a dark room when I turn it on it seems really bright for a few seconds .??Is this backlight bleedthrough? Black seems very black. The built in speakers are not adequate and if you do any music or sound for that matter, use auxiliary speakers for sure.

I am utilizing the image burn in protection, which is set to "on" as the default setting anyway for this tv. I haven't seen any burn in issues even though i have watched movies close to 2 hrs long with the black bars on the top and bottom of the screen.

I took it into a dark room and I could not see the screen. I suggest that you go online to Sony and download the owner's Manuel. I don't see anything about a backlight in it, but maybe I just missed it.

I am assuming that this happens when you change channels or between commercials. If not, and it happens in the middle of a program, then you may have a real defect. Even so, I bet it would be solved by the fix below. Here is the low tech way of fixing it. I also found some more complicated ones, but I used this and it works: "One issue I found annoying was the OPC backlight adjustment that dimmed or brightened the screen immediately after changing channels or going between commercials. Even on the "off" setting, this occurs, but turning it on and decreasing the range to 1 eliminated the problem." So just use Menu to go to Picture and turn ON the OPC. The go to Advanced (also under Picture) and go to Range of OPC. Set the range to 1. Save.
