I believe I've found the cause/answer for ME at least. I have my HD DVR on a shelf enclosed with a glass window. I think it's an issue with the DVR once it gets overheated. I've since cracked open the glass door and haven't seen it happen since...

I have the LN46B750 and experience an occaisonal blackout for a second when my HVAC kicks on. I also am not sure if this could possibly be my 4 year old D*TV dvr. Would like to hear what you have running at the time when this happens, if it coincides with a power surge, etc. It's driving me crazy.

I have this same issue. It doesn't happen often enough for me to consider it a "problem"...but I have certainly noticed it.

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.

I believe this happened to me 3 years ago. I looked it up and I believe it was a loose component on one of the boards in the TV. Mine was still under warranty and Panny had someone locally come by and fix it for us. Good luck.

I haven't had the video drop out while watching a movie, but the GUI for the net/usb function will not display half the time. My TV displays a message that it is not receiving any video signal, which is odd since I know the receiver is on.

Hard to say without more info. Was it it hit by a power surge? I don't know about this particular model, but I had a different Samsung model TV that this happened to and I found out the power supply went bad. I figured that out myself by taking it apart and probing around with a meter. But, I am an electrical engineer and not that intimidating to me. I found the replacement power supply board online for $150. I replaced it and no problems since. If you problem is common for your model, you'll see it everywhere on the internet if you Google it. That is what pointed me in the direction to look on my TV.

I have a 42LM6200 that after about 18 months would not boot up at all. I Googled the TV and found many articles about the boards in this TV being defective. Most repair shops wanted $150 just to look at the TV. I searched for a supplier and found a replacement board, the boards are no longer manufactured, so I ended up with a refurbished one. Spend about $90 for the board. It took less than an 1/2 hour to replace. good luck

I have the same issue with my two-week old 42B450, as well. The plastic bezel makes faint crackling noises as the unit warms up (lasts for about 30 minutes). It is definitely the plastic bezel since I can duplicate the sound by pressing the bezel along the top edge of the TV. Another Amazon post said that they had the same issue and so they returned the TV for replacement and the second one did not make the sounds. Am curious if the Samsung rep mentioned above actually has a fix for the problem.Except for this issue, the TV is excellent in every way.

I have had my TV two days. I love everything about it except that it has this memory loss problem. I am somewhat relieved to hear others have the same issue. It means I won't bother to get a replacement. But in fact I see no alternative in the market so will probably just keep this and bear with resetting stations. I think we should all be contacting Haier, however, to assure that they fix this thing in future models

I would keep an eye on it but be aware that this is a common issue with the TV's not the bulb. Sony actually settled with a HUGE number of people over the "blue blob" issue and optical block issues and gave them new tvs at discounted price. Sony is aware of an issue where the plastic melts inside the TV and some have had their entire inside warp (maybe I read something about a fire hazard also). My KDF-70XBR950 has a hole in the front of the lamp door where the plastic has melted and warped. Do an internet search for "Sony blue blob" or "Sony optical block problem" and you can read a ton about it.

Hey, I had the same problem with an LN55C650 and even with a new panel it did it. So the tech got on the phone and called and was told about the service bulletin and cut jumper number p854 on the 55" and that fixed it. So the new panel came back out but I got my tv fixed. Yay!!!

I experience the same thing but not as frequent. I am also having issues with it turning itself off. I was told there is a problem with the power pack inside the TV. it does have a 1year factory warranty but dealing with Vizio CS is a pain. I bought mine from Best Buy abd bought there extended warranty so right now I am waiting for them to receive some more in so they can do a swap for a new one. I happen to like this TV very much but it seems without an extended warranty you might be on your own. Good Luck.

I owned the Samsung plasma PN50B450. My home was recently burglarized and the TV was hauled off. I am here shopping for a replacement. Anyway, I play a lot of Xbox (which was also taken). I speak from personal experience regarding burn in and this set. There can be some image retention with this set. This is with the TV set at "cinema" and with pixel shift on the recommended settings even. The images fade with time (a few hours of watching something else or playing another game). You will only see these ghosted images on a white screen. As I mentioned before, they are feint and fade in a few hours or so. I never experienced burn in though. I owned the Samsung plasma PN50B450.

Yes, I am having the same issue with my same model television. Mine was purchased the end of 2/08, it started doing that about a month ago and it is out of warranty. Have you had your repaired? If so, what was the cost? wants $150 just to come out and diagnose the problem.

My PT61LCX65 has just had its light engine / LCD panel set fail. 7 years of age on a Panasonic. 14K hours. Never would have used a extended on it. Devices like these either fail in 6 months or many years after the warranty period. Look at a warranty vs what the TV will be worth in a few years.

Very similar issue: flickering problem on this 55 inch. This all began about 24 months after purchase. Does anyone have a solution other than calling a service technician and paying for the repair yourself?

Our Toshiba just started doing this. The picture freezes but audio continues as normal for about 10 seconds or longer then it shuts off. About 3 to 5 seconds later it turns itself back on. Did your problem start the same way.

Mine too, after about a year. Seems to be common for this TV. Mine could not be cost effectively repaired.
