Samsung LNT4071F Blue light won't go off Has anyone experienced a problem with not being able to get the blue light to go off above the on-off sensor on the front of the flat panel? I've gone in to the menu and selected to have it on only when watching TV and it works the first time you shut it off. However the next time you turn the flat panel on and then back off the light stays on and when I go into the menu it's set for "Always ON".

I know this is an old post, but thank you!!Worked great! Especially the step on switching from hdmi to tv. Thanks!

thx for the hint and guidance on how to fix this, odd thing is that after a year and a half the TV just decided to do this...no clue why

Our new LN-T1953H has the same annoying defect. Every time we select Blue Light: OFF in the setup menu, it comes back on later. Arrgh! Does anyone know how to fix this?

Thanks for the tip. I bet it is in store mode. I'll keep my Samsung. It's the best picture I've ever seen and all my friends say the same. I looked at the Xbr4 side by side and couldn't not tell a difference. At least not $1500 difference. You pay for the Sony brand name. Not me.

Make sure the TV is not in "Store mode" because it always resets the settings so that they will look good in the store. I would also recommend returning your Samsung for a Sony Xbr4. I went through 2 defective Samsungs before I finally woke up and got the Sony. It is far superior to the LNTxx71.

Some TVs don't allow going into the PlugNPlay menu. According to Samsung chat support, try pressing volume button on TV, then hold MENU for about 7 seconds. The word Dynamic should show up n the screen. If you press Info, the ShopMode will disappear.

I'm going to call Samsung tomorrow and will post any advice they have for a solution.

The TV will turn on when the Blu-Ray player is turned on. The other devices will turn off when the television is turned off. The logic is that by turning on the Blu-Ray player, the TV will need to be on to navigate and watch. But just because the TV is on doesn't mean the Blu-Ray player or Home Theater system is necessarily wanted each time. So as a power-saving feature, the entire lineup of devices won't turn on - but turning them on first will activate the television. So power on with the Blu-Ray/Home Theater system and power off with the TV - and the other devices will follow. Does that help explain? --Mr. S

It is actually for my son and I have not heard of him having any problems with it. I did try to locate drivers for it and was unable to find any, but we are running Windows 7 and it seems to be working fine without it. The blue light stays on even when the computer is off, my son doesn't mind it but thought I would let you know.

I have put the bulb away 'til next Christmas, but my memory is that it does not remember. It starts in a default mode every time it is turned on even if power is not removed. Others says it will remember so my memory is probably faulty. Maybe it only starts on default when you use the remote, but remembers with the wall switch. I did not experiment with the light switch dimmer. I would count on using the remote to dim.

We've been experiencing it off and on for about 6 months. Two nights ago, it was really bad...today...its not there. It comes and goes. In our case its a blue stripe. We've seen it whether its coming from the cable box or bluray player. I haven't played with it too much, so I don't have a pattern of what it does and how to defeat it. I'd like a comment from Panasonic. Our TV was 5 years old at Christmas.

Not 100% sure. It could be a misbehaving signal source. I assume that your Input 1 is either plugged into your Cable/Set Top box or a Blu-Ray play. Try cycling the power by physically unplugging the power cord on whatever is plugged into Input 1. FYI, HDMI is an "Intelligent" interface so it tries to electronically identify the type of signal source plugged into each input. Sometimes it works, sometimes it doesn't. When it does, things work more intelligently. For instance, when I turn on my Samsung Blu-ray player which is plugged into Input 2 on my Mitsubishi, the TV turns on too without needing to hit the power button on the TV Remote. And sometimes, when I turn off the Blu-ray player, the TV will turn off too. Another possibility would be to try a new HDMI cable. The cable should be HDMI 1.3 or 1.4 compliant. If you don't have a new cable, but you have multiple cables, try swapping them and see if the problem moves with the cable.

You have to unplug it for the blue lights to shut off....for some odd reason. It is normal for this product.

I just disconnected the blue LED. It's pretty simply. Pop the control panel from the front, not sides... GENTLY! Watch out because the filter reset buttons will just fall out. You have to unscrew another housing underneath the control panel to get to the light. I simply snipped it off with wire cutters and re-assembled everything. Works fine.

Hi TB, It is my understanding that the same image has to stay on the screen for many hours over a course of a very long time before burn in takes place however, at least on my TV set, the TV will turn itself off after so long. If you are still watching the TV when the warning flashes you have the option to push the OK button or let it turn off. Burn in happens only when the same image is left on the screen for a great number of hours not when using the TV for normal viewing or use.

It actually sounds like one of your cooling fans went out. Which would explain it turning off because of risk of overheating. With that being said you should probably replace both fans and the color wheel. They all run on bearings and if one failed then the rest WILL follow. The fans are pretty simple to replace and are priced at about $5 each. Plus why take the TV apart twice or three times!

My set never had the picture issue prior to the issue of the tv switching off entirely and not coming back on. I tried the side power buttons, and I also called Toshiba customer support whom walked me through holding down the power button and unplugging the tv for a while, etc. They were unable to help, so they directed me to my local repair shop. Called them, they seemed helpful, were supposed to order a new power supply for the TV. Haven't heard back from them...but after leaving the tv unplugged for a day or two, I plugged it back in and its worked ever since like a charm...have no idea what the problem was, but it works now...just hope it stays this way.

Well I too recently ordered the LNT4661F and sure enough, it snap, crackles and pops when you turn it on and off. I'll be calling Samsung on Monday to have someone come out and look at it. I just hope its as easy as replacing the power supply. I'll keep you posted.

I haven't had any problems with mine, but I did have a similar problem with another model and this is how it started before the whole screen went dark. I had a technician come by. He said it was the mother board and that he would fix it but he couldn't guarantee it wouldn't happen again. He said that it's best to replace the mother board, and if you have to do that you might as well buy another tv. I took a chance and he fixed the problem temporarily, then it died, so I threw it away and bought this LG. I've had it since July 2013 and it's worked fine. Mine is the same model in a 50-inch. I did buy the 5 year warranty just in case since it's new technology. With these smart tvs it's best to get the warranty because you never know. If it's still under warranty, you should return it and have them replace it before your warranty expires because once the mother board gives out it's too expensive to fix and you're better off buying another tv.

It must have been fixed. Mine will stay on as long as sound is passing through it. I've even fallen asleep with the TV on, and it didn't shut off. It will shut off if what you are watching is paused for a while, which it shouldsince there is no ssound playing.

Unfortunately the blue light does not turn off. I guess you could try to take it apart and remove the lights if they bother you. I just ended up getting use to them.

Mine had a intermitant failure, I gave it away and bought a Samsung lcd. The person I gave it to leaves it on all the time because it needs to cool down if they shut it off, HOWEVER THE FIRST ONE i PUT IN IT WORKED GREAT, MIGHT WANT TO CHECK WITH VENDOR

We have the same problem with our TV. The screen is normally very dim, then gets very bight. We've never had the screen go black. We have also noticed the same phenomenon that J. Wu mentioned about the lamp.Have either of you solved this problem? Were you able to exchange it?
