Samsung 40" 3D tv goes blank 1to 2 seconds

I purchased a new Samsung 40" 3D tv at Christmas time and the TV will go blank 1 to 2 seconds picture and audio from one to 10 times a day there is many people that say they have the same problem have tried all kinds of inputs it doesn't matter if you're using a cable box or a game station or a DVD. Has anyone else had this problem and does anyone else know how to fix it the repair shop said they do not know what to do at this time.

Page 62 of the manual.  Assuming you've followed all of those steps, turn off the automatic shut-off under the menu options, turn off all eco solutions that shut the tv off if no signal or movement is detected, and shut off anynet; all under the menut options.  Next, on your cable or satellite box turn off all the automatic shut-off options, sleep timers, etc. in the menus.  Same goes for the other sources you are using, blu-ray ps3, etc.  Make sure front touch panel is clean and free of dust, finger oils, etc.  Lastly, make sure light is not directly shinning onto the bottom of the front touch panel and that nothing is brushing against it.  Usually, these issues arise because of HDMI protocols (Samsung calls it AnyNet) which turn the tv off or on when something else is switched on or off.  It is supposed to simplify things but usually confuses people more so I recomment just turning AnyNet off on the tv and blu-ray player (assuming you have a Samsung).  If your cable or satellite has these protocols turn them off too. Otherwise, if the tv is on already and then you turn the sat. or cable box on, it will turn the tv off and vice versa.  They must be in sync for the HDMI protocols to work correctly so I just shut them off under the menu options.  Hope this helps.

  • Pavilion f1703 monitor goes blank 2 seconds after start-up

    When the computer is turned on, the monitor only functions for a couple of seconds before it goes blank..power light shows it to be working.
    If I turn the monitor off at the front power switch, and turn it back on, the same thing happens..2 seconds of normal then blank.
    In the couple of days leading up to this, the screen had a slight "flicker" effect going on.
    All ideas greatly accepted!!

    I am having the identical problem.  I hooked this monitor that a friend gave me and it worked great for several days.  There were no flickerings or any indications of a looming problem.  Then it started going blank after 2 secs and continues to do that.  I did see a warning about the "power saver", or something like that, was in operation.  Unfortunately, I can't get it to stay on long enough to go into the menue and see if there is anything I can change there.  Any help would be appreciated.

  • When plugged into wall, iPhone 4 says to restore at iTunes.  When plugged into PC the apple icon flashes 10 seconds and screen goes blank 10 seconds. The device never shows in iTunes.  How do I restore?

    I need to restore my iPhone 4 in iTunes.  I get this message when it is plugged into the wall.  When I plug it into the PC it doesn't stay on long enough for recognition.  How do I restore?

    Sorry, disregard the last response; I can't edit it. You should dry it BEFORE trying different cables. The safest way to go about this is dry your iPhone inside-out and to not turn it on until it's dry. Maybe there is a little moisture stuck inside preventing it from booting, but if you're lucky, it's not permanently damaged. The best way I've heard of to dry it is to leave it overnight in a tight bag with dry rice or, better yet, silica packets (those anti-moisture things found in packaged items). Maybe longer if you want to be extra safe. If it still doesn't charge without the Apple logo flashing, try using different Lightning to USB cables. Maybe it's just a bad cable, but you shouldn't test that until you've dried your phone.

  • My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me mad having to put my pass code in all the time and the screen keeps going blank :( HELP!

    My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me crazy as the screen keeps going blank and I have to constantly put in my pass code every few seconds. Can someone help me out please. The pass code lock is set at 10 minutes but it's happening every few seconds :(

    I've run into the issue and it seems to be related to an app not fully supporting the iOS you're on, the reboot doesn't usually solve it.
    I've solved it in the following manner(s):
    1) Backup the device to iCloud, then erase the iPad (Content and Network Settings).
    2) Setup the iPad and choose to restore from iTunes/iCloud Backup (wherever you backed it up)
    3) Perform any software updates
    I have not tried simply performing the software updates (which may fix it, but if it doesn't you won't be able to perform the above steps).
    Enjoy.

  • Mac with latest updates: installation window appears, shows message "Retrieving install" for 3 seconds then installation window goes blank. Why?

    Mac with latest updates: installation window appears, shows message "Retrieving install" for 3 seconds then installation window goes blank. Why?

    Hold down the option key during start up - you will be given the choice of which partition to use (Macintosh HD or Windows). I am having the same problem - Windows 7 seems to have installed but it goes to a blank black screen and there is nothing to do but force a reboot. I too have an i3 iMac... Windows 7 32-bit from original disc.

  • Screen goes blank for a fraction of a second

    hi all,
    i just got a macbook pro two weeks ago. I am pretty satisfied with this laptop but since its my first mac experience and i am expecting mac's to be perfect there are a couple of things ( may be minor) that are bothering me.
    first is, while working on my mac i have noticed the screen goes blank for a fraction of a second.
    second, i have mighty mouse but at times it stops working as well, in the bluetooth menu it shows that my mouse is connected but it won't work, so then i have to disconnect it and connect it back again.
    should i take my macbook to apple store or what
    any suggestion would be appreciated.
    thanks

  • My iPod nano will go into the sleep mode while a song is playing a second after the screen goes blank; the song will stop and I will then have to press the sleep/awake button to pick up where the song left off.  How do I fix this?

    My iPod nano will go into the sleep mode while a song is playing a second after the screen goes blank; the song will stop and I will then have to press the sleep/awake button to pick up where the song left off.  How do I fix this?

    Your problem is that your iPod is not sensing that your headset is inserted. There is a pin inside the headphone port on the Nano that senses if it is inserted fully. If it does not sense anything, it will pause playback to save battery power when the screen dims. Here are the solutions:
    Insert it fully. This will fix it for most of you. Press that thing in there all the way. You should feel and hear a full click when it is fully seated. If you can see ANY silver of the headset jack, it is not fully inserted.
    Debris inside the headset port. If you are totally unable to push the headset jack all the way, the most likely problem is that you have crud inside your headphone jack. Try blowing it out or slapping it against your palm with the headset port facing your palm to try and get the stuff out. If you look into he jack with a light, you should be able to see to the bottom. The entire inside of the headset port is white, so if it looks dark at the bottom, that is the crud that is keeping your nano from working.
    Headset jack or plug issue. If you cannot solve the problem with 1 or 2, then there is likely something physically wrong with either the headset jack on your headphones or the headset port on the nano.
    If none of the above works, you need to take it to the Apple store or wherever you purchased it. I think they are still under warranty.

  • 30" DP monitor keeps going blank for a few seconds.

    I have 2x 30" montiros:
    1. dell U3011 Display port 
    2. dell 3007WFP with active Dual link DVI to displayport.
    Both cost in the region of £1300.
    Neither will work with the think pad W530 + 2000KM, but both work flawlessly with macbooks and any dell with DP.
    Only the thinkpad doesnt work.
    The symptoms are this:
    1. U3011: goes blank (black) for 2s every 30s.
    2. 3007WFP Blank for 30s, flashes the desktop for 2s, then goes  blank again.
    Clearly there is a serious issue with the thinkpads displayport or drivers.
    Both monitors work perfectly if I unplug the minidsplayport from my thinkpad, and plug it into any other laptop with mini-displayport (have tried 2macs and 2 dells - all 4 no issues).
    If I plug the monitors into the mini-doc3, they work fine, no flashing.  If I plug either into the mini-displayport on the lalptop itself, then they flash.
    The problem is I only have one docking station, and have one 30" at work, and one 30" at home.  
    I desperately need a solution so I can work at home.
    Both monitors showup with the correct name and resolution in the windows 8 "screen resolution" page in the control panel.
    I have also tried swapping out my displayport to mini-displayport converter.  Neither make any difference, and both work perfectly with any other laptop and my monitors.
    The Nvidia control panel version is 7.5.800.  If I do "check for updates" it says "no updates available"
    There is a simlar problem witht he audio through the monitor.  If I connect directly to the mini-displayport on the laptop, the sound dissapears for no reason for around 20s every 60s.  IF I plug it into the DP on the doc, sound never drops.  
    Any ideas?

    Are you using "Optimus mode" set in BIOS?  Or are you using "discrete graphics" set in BIOS (which will also allow you to install the latest retail nVidia driver to support the K2000M)?  Try "discrete graphics", install the latest nVidia driver (not from the Lenovo site for Optimus, but from the nVidia site for the K2000M), and see what happens.
    Are you using a short miniDP adapter and also a regular cable?  Have you tried a simple straight-through single cable with the proper miniDP connector at one end (for the W530) and the proper other end as required by your monitor?  I suggest going with the single cable, and avoiding any adapter.

  • Using COMMAND 'B' to cut - viewer goes blank?

    Not always, but often when I use the COMMAND B to make a cut in a clip - my viewer (which I have on a second monitor) goes blank.  Stays blank for awhile, then comes back into service.  I'm wondering what might be happening here?

    I had the exact problem you report with my core duo Mac Mini connected to a Syncmaster 204B. This problem persisted when I returned the monitor several times to Samsung for replacement 204B's. They eventually upgraded me to a refurbished 204T and the problem disappeared.
    It seems to me that Samsung has some real problems with screen blanking when their monitors are hooked by DVI to certain Macintoshes. For anyone contemplating a Samsung monitor, I'd recommend another brand until it's known that this screen blanking problem has been resolved with all Samsung models.

  • HDMI out goes blank

    I purchased a Samsung commercial signage TV for running videos and powerpoint shows in my tradeshow booth. When I connect my HP ProBook 4540 laptop via HDMI to this TV, everything looks perfect but only for about 10-20 seconds then the display goes blank and I have disconnect the HDMI cable to get my laptop screen to come back on. I can reconnect the cable and again the TV pops on, looks perfect, and blanks out after 10-20 seconds. I have tried mutiple HDMI cables, checked and rechecked the port settings. The resolution comes up correctly every time (1080x1920) and I've also verified that the TV works perfectly with other computers (i.e. my Win7 desktop). Why would my laptop cut signal to the HDMI port? Hauling my desktop around to trade shows is not an option! ThanksBelldog Oh, BTW. It's AMD Radeon graphics.....  

    Hey Gmack07,
    Thanks for the question. I understand that you are experiencing issues with mirroring your iPad via HDMI. What adapter are you using to accomplish this?
    For Apple-branded adapters, see the following resource for troubleshooting information:
    About Apple Digital AV Adapters for iPhone, iPad, and iPod touch - Apple Support
    http://support.apple.com/en-us/HT202044
    Troubleshooting
    If you encounter an issue using the Apple Digital AV Adapter or VGA Adapter:
    Disconnect and reconnect the adapter from the iOS device and display.
    Connect directly to the TV, projector, or external display using a known-good VGA or HDMI cable.
    Remove any VGA or HDMI extension cables or converters.
    Note that accessories that convert a VGA or HDMI signal to other video formats (DVI, Composite, Component) are not supported.
    Ensure that you are using the latest version of iOS. Some Apple Digital AV Adapters require iOS 5.1 or later.
    When using an Apple Digital AV Adapter manufactured before early 2012 with iPad (3rd generation), you may see the "This accessory is not supported" alert. Dismissing the alert will allow you to use the adapter.
    For optimal performance, you may need to adjust the video resolution or settings for your display. If your display offers an "auto detect" or "factory default" setting, you may be able to use these options to optimize video resolution and display.
    Thanks,
    Matt M.

  • Firefox crashes when I load any youtube video on the latest version, it not only crashes firefox but my whole computer goes blank and I have to restart, why is this?

    Backstory: There are two possible events that could be causing this
    1: At some point I may have followed a ''Tinyurl' link that consquently lead me to a youtube video, to which youtube worked perfectly fine before hand, and this is where i witnessed the first crash. Theories into whether this link, previously stated, may have done something to my system have been thought about, but the fact that youtube still works on the latest Microsoft Internet Explorer seems to present the idea of a virus or an error redundant. I own the latest Macfee antivirus software and Ccleaner(running the registry check) and have run them complete with disc defragment and scan disc error recovery along with an additional malware scanner. Nothing seems to have come up on anything. After doing all this, my last resort was System restore and this seemed to solve the problem, mainly because i had an earlier version of firefox. therefore i resisted updating for aslong as possible whenever it told me to update. but the otherday i thought i'd risk it again thinking it may have been a problem alot of people have been having and it would of been fixed, but sadly it hasn't. this lead me to google the problem and was advised to start firefox on 'safe mode' as there may have been a confliction between add ons or plugins with youtube or some thing like that, but sadly that hasn't worked either. The plugins i had installed with it were the ones firefox has told me to get, or recommended and the only two addons i had on firefox was Adblock plus (fanboy subscrip) and Noscript.
    Details of what actually happens: go to a youtube link, video loads for about 2 seconds(both video and audio), screen freezes, and flashes maybe once with some small lines across the bottom half of the screen horizontally towards the right corner, then the screen goes blank and makes my laptop dorment, but still running, thus I restart my system.
    Sadly now when I system restore there isn't a point far back enough before this problem. So its either i downgrade(which seems to be the only option) or simply stop using firefox, as internet explorer works perfectly fine. however running firefox with no scrip and adblock plus is the ideal browser customisation, which is why this is rather annoying.
    so number 1 was the tinyurl theory and i must admit i was abit foolish to follow such a random link, but whats happened has happened.
    2: basically there is a major disfunction with the latest firefox that has to with the addons i have included onto firefox and this seems to be causing a terrible effect on my system.
    in a nutshell: firefox worked perfectly before upgrading to the new firefox and before i followed this link, the rest of my system is completely normal and virus and error free or so it says, Other browsers seem to work also. safe mode does not cure the problem.
    Running on a customised Dell laptop, which is pretty midrange-toprange and hasn't been active long, so it has the general HD video card thats included in all Studio 15 Dell laptops.
    any help appreciated.
    cheers.

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.
