Both techniques use an LCD screen that emits no light by itself. The difference is in the lighting behind the screen. With LCD screens this is done by CCFL (cold-cathode fluorescent lamp) and LED makes use of LED lights.

First, I would like to mention that both an LED TV and a LCD TV are actually LCD TVs except that first one has LED stripes and the latter one has CCFL Backlights- (Florescent Tubes).

Repair- Suspect a stuck VOLUME down(-) button. A normal button will give you that tactile feel, compare it with the other buttons. If it feels similar to the other buttons then it could be the switch behind that button. The switch used in most front panel buttons are called ‘tact’ switch, obviously named because of that tactile feedback

Repair–Suspect T-Con Board–Sometimes, just resitting, unplugging and re-plugging the flexible ribbon wire from the T-Con board to the LCD panel, will fix it-If not replace T-Con Board-

Symptom- the unit powers on with a steady red light on the front panel. However, I could not turn the unit on using either the remote or mechanical buttons. The red standby light never flashes and remains steady.

Emerson LF501EM5F TV Symptom- Bought it less than 2 years ago and now won’t turn on. The Led light is solid red once I plug it back in. I took the rear panel off and can hear a small humming sound in the marked location. Repair- Replace Main Board

Funai LC320SSX LCD TV- Symptom- ” It does not turn on at all. It use to turn and turn off then it just stop turning off” Repair- Bad capacitor on Power Board

Replace- Replaced the power board with a new one and replaced the main board as well and also replaced the t- con board–No ChangeRepair–1 burnt Led on LED Strip inside panel–

Hisense 50K23DG LED-LCD HDTV - 50K23DG Symptom- red light comes on, flashes 6 times Replace- Replaced the power board with a new one and replaced the main board as well and also replaced the t- con boardNo Change Repair1 burnt Led on LED Strip inside panel

Insignia NS-L42Q120-1-A LCD TVSymptom–The TV plays awesome beautiful pic, but powers down , I can turn it back on and it plays great! Then powers down– Repair–Firmware Update

Insignia NS 50D550NA15 TV Symptom- While watching the tv I could hear a sizzling sound a flickering light in the top right corner and then the picture faded to black . I have changed the power supply board and with the new board installed there is power and audio. I can see a picture doing a flashlight test but I do not see any backlights. Repair- Replaced Power Board, have sound no picture. Can see movement, with flashlight-Apparently, shorted Mosfet on Power Board, burnt LED strip inside panel.

Symptom–While I was fixing a ribbon cable on LCD screen TCON board popped. Replaced with new one but now my screen has sound but image is extremely bright. With image but no colors.

Repair–Replaced T-Con Board–No change. Found shorted VA1-(Variable Resistor) Since it is on the Control Board, which is Micro Soldered to the Panel and cannot be replaced, it`s considered as panel failure-

Activate the TV’s menu — let’s see if that flickers too. We want to see if the menu flickers, because it might be only the TV’s picture that flickers. If the menu flickers, then we know we’re dealing with the panel or the TCON. If only the picture flickers and the menu is steady, then we know we’re dealing with the Main board.

LG LED TV-50LN5310 Symptom–Turns on quick white flash (Backlights) then sound, no picture- Repair-Burnt Line inside panel on negative side–Re-soldered negative line on connector

Symptom–I have an LG TV and a Sony DVD player, and every time I try to watch a DVD, the display screen (for color mode... vivid, cinema, sport, etc.) keeps popping up. It pops up on one side, then goes away, then pops up on another side, then goes away

Now, You only have 2 boards- Power Board and Main Board. What I need you to do, is disconnect the LVDS Cable, the cable that runs from, Main Board to T-Con at top of Panel–See picture below- Disconnect at red box, plug in TV. Does it come on–

Panasonic 42 THAS610D LED TV Symptom- backlights are looking fine, no picture- Repair- Checked SMD Fuse is good. Replaced T-Con, no difference When removing 1 FPC Cable(Cable at top of T-Con, we get 1/2 picture. Was considered panel Failure’

Philips LCD TVSmoke like shadow on one side of the screen It is most likely a LCD panel problem. It is costly and impractical to have it replaced. You can only discern the smoke like shadow on low light scenes

RCA 42″ Flat Screen TVSymptom–I have only half the screen is working . After it warms up the you can see the whole thing. Repair-This problem is either the T-Con Board or Panel Failure–

Symptom-When the TV is plugged in the Red Light is on-No Blinking-Then when I turn the set on with either the front panel Button or the remote control the light then goes off and nothing happens, No sound or picture

Repair-3 shorted LEDs inside panel–In stead of replacing strips, put a jumper resistor and soldered in–Use 5K Resistors is best–Remember his LEDs where in Sequence and not Parallel–

Samsung-LCD TV Multiple Color Vertical Lines- This type of TV problem, we must call out the OSD Menu to confirm–If the OSD Menu is showing normally on the screen, but the-background is full of color vertical lines then this symptom is caused by the Main Board or LVDS Cable–

The only thing you have to do is disconnect the cable between the power board and main board. Then, power on your TV. If you see the back light in the back of panel the problem is the main board if not, the power supply is the problem.

Sony LCD TVHas dim picture–1 of the CCFL(cold cathode fluorescent lamp/light) could have burnt or the circuit(inverter) that powers it might have failed. A technician will usually swap the connectors between the suspected dead lamp with the other good ones. The backlight consist of more than 2 CCFLs. When swapped and the dark area is at the same location then you have a bad lamp, otherwise suspect the inverter.

Sony 52″ LCD TVSymptom-Turns off by its self after a few minutes- Try to check first TIMER Settings on the TV set. Disable features such as auto-off and sleep timer. If everything seems to be ok, check air vent holes for possible obstruction and clean, maybe a sign of overheating.

Repair-Activate the TV’s menu — let’s see if that flickers too. We want to see if the menu flickers, because it might be only the TV’s picture that flickers. If the menu flickers, then we know we’re dealing with the panel or the T-CON Board. If only the picture flickers and the menu is steady, then we know we’re dealing with the Main board.

Symptom– Turns on, then says “Digital Television” then turns off.( Short flash of Light...and a short Display ) This type of failure is almost always caused by Inverter circuit failure, in the majority of LCD TV’s. Check the pico fuses or smd fuses and HV Transformers in the main inverter circuit, but with these models, I know that one of the HV Transformers, often develops a open a secondary winding. It is usually the HV Transformer, at location T1100

Symptom–Nothing happens if I press buttons from the remote control or even on the TV panel. If I unplug it for an extended period of time it seems to “boot up” right away and everything is fine.

The LED back lighting is pretty even, it"s not edge-lit, so it doesn"t suffer from the bright-edge effect that many edge-lit HDTVs have, and not buying an edge-lit model was a main deciding factor. The off-axis viewing angle- left to right and below to above is pretty good, not as good as my CFL back-lit Samsung, but the LG cost a small fraction of the Samsung and there will never be a room full of people seated around watching it in my office like the Samsung in the living room. If you get off-axis far enough you will see some variation in the backlighting on scenes that have a uniformly dark background, like movie titles over a black background, but I doubt that most people would ever sit that far off-angle or notice it.

The built-in speakers are down- and rear- firing, intended to bounce off what the HDTV is sitting on and/or the wall behind it if wall-mounted, and are adequate if you"re in a quiet room. In a noisy environment, you may not find them adequate. In that case, there is an optical output on the back, intended to be connected to a speaker bar with it"s own built-in amplifier or to a sound system (stereo or A/V) . One of the inadequacies of the manual which I"ll discuss more fully later is that there is pretty much nothing mentioned about which models of LG speaker bars are compatible except the trade-mark "SoundSync" which I have not found mentioned anywhere in any of the LG speaker bars online or on the LG website itself. Something I noted about the volume control is that it appears to operate on a linear curve rather than logarithmic curve (which is normally used because it closely matches the response of one"s hearing)- what this means is when you increase the volume to 50% of it"s range, the apparent volume to your ear will sound like about 90% of it"s full range, and there will be a much smaller increase in sound level when increased from 50% to 100%. An oddity that hopefully can be corrected in a future firmware upgrade, and not a deal-killer.

Another omission is information about the optional Skype camera- in the manual it only mentions the models AN-VC4** and AN-VC5**... after a lot of searching, I found only one model, the AN-400 on an LG foreign country website. Searching for this camera turned up sellers in Hong Kong, Great Britain and Australia (on Amazon and Ebay) for very high prices ($200+). Apparently the AN-VC5** is not yet available in any country in the world... This HDTV is a 2013 model, so maybe the accessories have not caught up with the HDTV model year yet. After a lot more searching I found the AN-VC400 available in the US for $99. From comments on the LG User forums it appears that one must use the LG webcams only with this HDTV. I tried several webcams I had and they were not recognized by the HDTV. This is kind of absurd for LG to exclude something as ubiquitous as a webcam from working unless it is one of their own manufacture, in my opinion. I"m still searching to see if other users have found cameras that will work, but the ones I"ve tried so far have worked universally on both Apple and Windows products and are very generic. The reviews of the LG cameras have been mixed.

Also, in the menu system there is mention of connecting to wireless headsets, but no mention of anything about that in the manual. When I was searching for a new set of surround headsets I did run across a few that said they were compatible with some LG models (this particular LG model was not in the list)- I believe they were Sennheiser brand, but I"m not certain. There is no indication whether these are Blu-tooth, or other RF or what frequency range they operate on.

Wireless connection- The MAC address (the unique hardware ID for the internal wireless adapter) is nowhere to be found. Because I"ve set the security up on my network to only allow access to devices which I own by including their MAC address in the router access table, I had to spend a significant amount of time to identify the MAC address for the LG HDTV before I could access it wirelessly. This information is required by the FCC to be displayed on the outside of the device on a tag or sticker, but was not on the LG anywhere. I realize most people may not be affected by this, but this information should have been displayed for those whose are security-minded like myself.

Also, I read one other reviewer mention that the screen is a matte finish... I would have to disagree with this. I have a Samsung HDTV that has a glossy screen, and a Samsung monitor that has a matte screen... I would have to call the LG screens for this model semi-gloss- you can definitely see reflections of objects and lights in the screen that are clearly defined when the HDTV is off, unlike my Samsung monitor where any refections appear as undefined blobs of uneven lighting, but somewhat less pronounced than my Samsung HDTV which has clearly defined reflections when it is turned off.

An interested shopper asked whether the Smart App supported Amazon Prime yet... the answer at this point is that the firmware for both models I own does not support Amazon Prime as of 6/29/2013. Hopefully it will be updated in the future like some other LG models allegedly have been. I have a ROKU box that supports Amazon Prime, and honestly, Netflix video quality is much better to Amazon Prime at this time and Netflix has a much wider variety and greater quantity of programming, so I"m not really put off by not having Amazon Prime support at this point. Hopefully Amazon will up their game and improve the quality of their streaming products in the near future- I am a Prime customer, but I really don"t take advantage of my access because the quality disappoints me whenever I watch something on Amazon.

One final note about screens on this model... the 42" model in my bedroom is on top of a bookcase, and when lying in bed I have to look up at it... if my track lights are on while watching TV, there is a definite reflection from each track light that is reflected in a rainbow on 4 axis from each light source... it"s very pronounced, and is likely an artifact of the light reflecting on the LED diffusion panel at the rear of the LCD screen; my Samsung HDTV does not exhibit this same tendency, it simply reflects an image of the light itself, however the Samsung has CFL illumination, and a different backlight diffusion technology, and this could be a characteristic of the LED illumination engineering. At any rate, when viewing the screen from eye-level, these reflections are not visible. Eventually, my plans are to wall-mount this and at that point I can tilt the screen slightly down and the reflections will no longer be a factor. As I stated below in my original review, I would not pick these models as my primary HDTV for my living room or home theater, but I think they are very good choices for what I purchased them for... for secondary occasional use in my home office and bedroom.

Update 8-21-2013- I did get a wall mount for the 42" LG in my bedroom and angled it so that I was viewing almost straight-on while lying in bed, as I mentioned above that I was planning to do. This was very effective at getting rid of the reflections from my track lighting that I mentioned above. The wall-mount was a fairly simple slimline mount, and only cost $20 on Amazon, so it didn"t break the bank. I have a low platform bed and the LG is mounted fairly high on the wall, so unless you have a similar viewing scenario, you should not be affected by the same kind of reflections.

Since you are in the UK, it may be worth forwarding this to the Information Commissioners Office: http://www.ico.org.uk/ and pointing out to LG that you have done so... It would be interesting to see how that might affect their next response.

You may also want to draw LG (and the ICO)"s attention to the fact the request appears to include cookie information, and to the infamous "cookie law"...

1/ Surely, it doesn"t matter what is in their T&Cs if the option to switch data collection off doesn"t work, then that"s a serious matter and needs to be investigated by LG?

I expect the "Tom" character in the email response from LG is a lowly figure in the food chain (equivalent to Call Centre staff). To pursue this, one would need to go considerably higher.

Sniffing communication between 2 endpoints (TV<-->LG => TV<->YOU<->LG) is a Man In the Middle by definition regardless domains or whatever. The only "man in the other side" is LG. :)

LG"s http server, regardless of type, maintains logs of all requests made of it, which include (amongst other things) the user-agent (what browser), the timestamp, and the contents of the request.

The fact that this is sent in the clear is also worrisome; anyone capable of intercepting your network traffic now knows you have an LG TV on it, and can (trivially) determine if you are home watching TV, or (some difficulty) research whatever current exploits that kind of TV is vulnerable to.

ICO is the correct people to follow this up with. Regarding the T&C"s line LG are going with, it appearers it could be an unfair condition (especially if not pointed out in laymen terms during activation) and the OFT may be interested.

Note the different URI than the one where watching habits are posted to; note the "smartshare" in there. LG TVs sport a "Smart Share" feature, so isn"t this related to the LG Cloud feature and isn"t it just looking for the file in your own "private" cloud?

I saw a blog post which reports that LG smart TVs contain spyware which sends to LG detailed information about what is being viewed and even the filenames of any files it discovers.

The author asked LG about it and they disdainfully said it"s up to the retailer to make "you agree to being spied upon" (I paraphrase) a contract term at the point of sale. Please see their reply in that blog post.

I purchased a LG smart TV and blu ray player from your Sheffield branch. The sales experience was very good but it was never explained to me that such a contract term did exist. If such a contract term was to exist then it would need to be pointed out at the point of sale, as it is not possible for the manufacturer to add further contract terms after purchase, regardless of whether or not they present me with pages of legalese and an "accept" button. UK law does not allow it.

I do not consent to any usage information being transmitted to LG (or anyone else) from the products I purchased from you. Had this behaviour been made clear to me at the point of purchase, I would not have made the purchase.

2. Had LG advised you that you must ensure that additional contract terms are explained to your customers as part of the sales contract? Can you please provide me with copies of the materials that LG provided to you about this?

4. For any customer who has purchased these products without agreeing in advance to this intrusion on privacy, will you provide a full refund, regardless of product age? I"d expect you to reclaim all monies and your costs from LG.

I assume that you were not expecting this problem to land with you, but unfortunately LG"s reply does make clear that they are making it your problem. Perhaps they will have greater respect for the purchasers of their products if you get involved.

Just to note that I"ve had a helpful email and phone call from Richer Sounds. They are unimpressed at LG, have tried to raise the issue with them and are getting only the bland "Customer privacy is a top priority at LG Electronics" reply.

Unfortunately, what you have told me makes me more certain than before that LG is in serious breach of EU Directive 95/46 on "Data Protection" in regard to the collection of data using my product.

LG cannot insist that I submit to being spied on in order to use a product that I purchased, unless this is made perfectly clear at the point of sale when I can still decline without losing money.

I intend to report this offence to the Office of the Information Commissioner and OFCOM tomorrow. I would urge LG to prepare a firmware update as soon as possible to rectify this situation.

I am speechless that LG would choose to treat its paying customers in this way; by stealthily monitoring them and selling the resulting information to advertisers for additional profit.

I discovered similar activity from my Lg TV shortly after I bought it last year. I was infuriated to see budweiser and mcdonalds banner ads shortly after setting the TV up. I also discovered quite a lot of links being generated to a lot of non-lg sites for ad serving and activity tracking, with many of URLs going to blank or 404 pages. I think the activity tracking is a lot worse in the U.S.. I received a similar response from lg support, with excuses that the ads and tracking allow them to provide a better experience blah blah blah. I have blocked all the hosts via my router. I"m not playing this game over a device I OWN.

To those of you who seem to be aghast at this - how exactly did you think your SMART TV was getting it"s SMART"s? And as we laughed at many of the comments here at the office - do you really think that your other media devices aren"t sending data on you back "home"? You live in a connected world where much of the free services you use are powered by advertising - because things like hosting, development and so on costs money and if you aren"t going to pay someone else has to. The point is not to worry about the fact that your TV is sending your viewing habits and penchant for midget porn to LG. The point to worry about is that they offer to stop sending this data as an option but don"t honour that contract. I"m pretty sure that"s no legal but I"m not a lawyer.

Nothing supplied on LG TVs requires advertising and/or tracking. The streaming services these TVs have are either paid for via their own subscriptions or their own in app advertisements, same with the 3rd party apps in their app store. The price paid for the TV should be enough to cover the cost of development and to included the often lackluster media center options. If it isn"t, then they need to reconsider how much they"re going to charge for these products. The idea that LG customer service is trying to absolve themselves of responsibility and make the retailer to blame, at least in the U.K., is absurdity at its finest.

There is an easy way to stop this, just send LG a notice that your consulting fees are £500 per day or £1 per byte of data transmitted, whichever is greater, and then bill them for using your information that they so desperately want from you.

My US lg looks similar but there is not option to disable data collection. It would be limited to usb and dnla played content because of our screwed up cable system that requires a box.

The irony is that LG probably wasn"t using the data anyway - I know that 404"s can be spoofed, of course, but never attribute something to malice that can be explained by incompetence...

2. Whenever you upload a video file to your USB, rename it things like "jihad for beginners", "101 to plan before your rampage", "Yes, I killed your dog" and "LG UK HQ blueprints". Get creative and have fun with it.

Well, this is an interesting coincidence -I was starting to look at the same things after a software update to my LG TV popped up a 50 screen "update our new privacy policy" sequence on reboot. You are ahead on me on wiresharking

This would almost certainly place LG in violation of the Data Protection act and the EU DP directive. I have been unable to match my device serial number to the device ID that was being transmitted - but this statement indicates that they can and do match it back to your name.

I"ve written to John Lewis customer services pointing out this article, and how LG are fobbing this issue off onto them. I"ve asked them to get LG to explain what the hell they are playing at.

The terms & conditions of the EULA (End User License Agreement) states that LG can gather information from the TV and you would have agreed to this as it would have come up when you set up the TV.

Will certainly be blocking this tonight. Personally i"m not as fussed over watching habits being reported but the transmission of what is on external media is ridiculous. I need to get a copy of the terms you accept when you start the TV. If there is a breach of the Ts&Cs the target IP (for gb.ibis.lgappstv.com) resides in a block of IPs managed by RIPE, who will investigate misuse of its network (http://www.ripe.net/data-tools/db/faq/faq-hacking-spamming)

I was thinking about purchasing one of your smart televisions, but have just discovered that you collect all viewing information, including what programmes are being watched, who is watching them and for how long, and that you are also collecting data from any usb connection to the television. This even includes file names and names and names of children on those files. I understand that you also offer an option to “opt out” of this, rather than “opt in” and that even when the opt out is selected you still collect the information. You don’t offer any guarantees regarding the safety or security of this information, you are allowing it to be passed over the internet unencrypted where anyone can collect it. If you could confirm these points for me before I purchase the television, I would be extremely grateful. I see also that you say that it is the responsibility of the retailer to inform the customer, and that it has nothing to do with your company or televisions...Are your retailers aware of this procedure. I always thought that when I purchased a television it was for the purposes of receiving information rather than divulging persona information for free. Is this the way of the future for L.G.? Would you like your children’s information, or your own private information spread over the internet, without your being aware or being asked for your consent?

You know, now that I think about it, I"m not sure what"s worse about the mention of encryption. I mean, it can be intercepted if its not encrypted (not like LG would care, they just want the data, so what to them if others spy on your viewing habits) but on the other hand if this WAS encrypted then it wouldn"t have even been discovered..

It does mention at the end though: "If you have any questions about this privacy policy or our privacy practices, please contact us at [hiral.gandhi@lge.com]"

When the consultant - Hull-based Jason Huntley - contacted the South Korean company he was told that by using the TV he had accepted LG"s terms and conditions, and that any remaining concerns should be directed to the retailer who had sold him the screen.

"The system grabs tiny fragments of content from small regions on the screen and throws them to the cloud for recognition, picking them from 10 different frames in each second. Collette told us that the ser-vice would be on 10 million TVs by mid-2014 and now it is headed for LG smart TVs being sold in the 2013 range as well as being downloadable to those in the 2012 range."

You can relax about Cognitive. I contacted their CEO at the same time as LG and received a reply saying that they have not used this technology in the UK yet.

If that happens and you think on it, it could be this exists for espionage reasons, and LG has been co-opted by an enemy government, and their electronics will need to be removed from all governmental establishments.

@LGNordic I will never buy any LG device, with or without ethernet, if there is not acceptable answer http://doctorbeet.blogspot.co.uk/2013/11/lg-smart-tvs-logging-usb-filenames-and.html … for #spying

If there was no web server on port 80, his TV would not be able to stable connection at all and he wouldn"t be able to see all those requests sent to LG.

I have a USB stick in my TV with family pictures on it. Seemed like a good idea at the time. Would it sometimes take these JPG files, without my consent and send them across the www to LG?

We are looking into reports that certain viewing information on LG Smart TVs was shared without consent. LG offers many unique Smart TV models which differ in features and functions from one market to another so we ask for your patience and understanding as we look into this matter.

after finding out about your findings via a German news site, I did some wiresharking on my German LG LM660S and noticed exactly the same behavior es you did.

Thanks for this useful info. I am not computer literate as others obviously are - but I went into my Sky Router / Security / Block Sites and entered the sites listed at the top of the post; all relatively painless. I have cleared the log and have ticked the box that says record attempts to access blocked sites - I will check back tomorrow to see (if anything) is being sent from my LG TV.

I bought an LG smart TV in Finland just a few weeks ago. Unfortunately I had not heard of these finding at the time. If I did, I would not have bought the TV.

One of the URLs contains "smartshare", which, according to LG"s website, tries to find additional media information. So the resource could be information on a movie / song etc. and the conversation between your TV and LG"s server might have been as follows:

So while LG"s answer to your request is hardly satisfactory and it"s reasonable to have privacy concerns, I don"t think you have been a victim of Orwell-like spying.

Just read on the BBC website that LG have promised a software fix to make a "no" setting mean exactly that after admitting they collect viewing information, even after users have disabled the function.

Richer Sounds received a response from LG and forwarded it to me yesterday evening then followed up with a phone call today. I got the impression they"d have been prepared to return my TV to LG but, as there is a firmware update coming, I felt it would be easiest to await that.

"At LG, we are always aiming to improve our Smart TV experience. Recently, it has been brought to our attention that there is an issue related to viewing information allegedly being gathered without consent. Our customers" privacy is very important part of the Smart TV experience so we began an immediate investigation into these claims. Here"s what we found:

Information such as channel, TV platform, broadcast source, etc. that is collected by certain LG Smart TVs is not personal but viewing information. This information is collected as part of the Smart TV platform to deliver more relevant advertisements and to offer recommendations to viewers based on what other LG Smart TV owners are watching. We have verified that even when this function is turned off by the viewers, it continues to transmit viewing information although the data is not retained by the server. A firmware update is being prepared for immediate rollout that will correct this problem on all affected LG Smart TVs so when this feature is disabled, no data will be transmitted.

It has also been reported that the names of media files stored on external drives such as USB flash devices are being collected by LG Smart TVs. While the file names are not stored, the transmission of such file names was part of a new feature being readied to search for data from the internet (metadata) related to the program being watched in order to deliver a better viewing experience. This feature, however, was never fully implemented and no personal data was ever collected or retained. This feature will also be removed from affected LG Smart TVs with the firmware update.

LG regrets any concerns these reports may have caused and will continue to strive to meet the expectations of all our customers and the public. We hope this update clears up any confusion."

I think there is a problem with LG"s claim that "Information such as channel, TV platform, broadcast source, etc. that is collected by certain LG Smart TVs is not personal but viewing information."

Sorry LG! Remember how "Customer privacy is a top priority at LG Electronics"? Prove it by complying with the law! Your data collection must be opt-in, not opt-out, and you must clearly inform users about exactly what is being collected, not bury it in a 30 page privacy policy.

Thanks, Sue. Just turned my TV on and there is a software update for installation - version 06.01.28. I have an LG 550. Hopefully, this will close the loophole until the next one is found.

I think we are forgetting that a lot of this sort of information and more is available and used on all digital platforms - PC, Mobiles and Laptops. It is pretty standard. It does not however allow a company to personally identify a user and that is where the law steps in. I would rather have a relevant ad than one that is not useful for me. Advertising is a necessary requirement and allows consumers of the luxury of free content. I would rather have relevant ads than pay for content. It is a trade off. I think LG"s response was the right one. I have many of their products and think they provide quality products at good prices. I too have an LG Smart TV and to be honest most of the ads I see are not relevant. I see a lot of car ads and I don"t even drive!

You miss the point - I do not mind targeted ads where I am using free services (Google Mail etc.) but where I have PAID for a product and SAID NO to information gathering, then I have every right to object to someone (LG in this case) data mining my usage.

I just picked up an LG 42LN5700 at Costco in Canada. Brought it home & decided to read some reviews and found this blog. Thanks for making this public! I am considering taking my TV back. If they want the data, they should have to ask for it, not hope that I never notice. I just tweeted this:

I have a LG 47LM669 smarttv and just update to 4.51.07 being forced to agree to LG"s term of use before being able to use my TV"s smart functions. It is a nordic/scandinavian model.

Hi DoctorBeet, I appreciate your work on this, it"s highlighted a major problem with LG"s privacy policy and data handling. I have a 42LN575V set which was dialling home, until I blocked the domains in my router. Smart functions are still working (Lovefilm / BBC iPlayer / Smart Share etc.)

I have followed this thread with great interest from here outside Washington DC. I JUST BOUGHT an LG 47LN5700, and have been quite concerned since stumbling on this news of LG"s spying a couple days ago.

My problem is that I am rather unknowledgable when it comes to network routers. I don"t know exactly how to block those domains on a Verizon Actiontec router. However, I know that my TV did at least two firmware updates in the past 3-4 days. Can I safely assume that I am safe from LG"s spying, as long as I have turned off "collection of watching info"?

Thanks for uncovering this, DoctorBeet. I"d just read this after having purchased a LG 42LN5758 which does send filenames from USB too. There were some additional issues that annoyed me

according to German computer magazine c"t, LG has changed what data is being transferred with their current update 04.20.29 for LN and LA models. Apparently there"s no unencrypted transmissions (of filenames) anymore. I"ve uploaded a small dump to my blog, I"m not quite sure everything is a-ok, what is your take on this?

All the unencrypted monitoring traffic has vanished but I have detected NEW data being sent to GB.info.lgsmartad.com which is encrypted. I have blocked this traffic since it looked suspicious to me.

My 47LN5700 just downloaded v. 5.00.30 of the software about three days ago. However, I have no idea, nor any way of determining, what that version does.
