Apple TV -- No Signal Message

Hi.
Apple TV won't put a signal out through HDMI when it wakes from sleep. I've waited, nothing. I've switched TV inputs, nothing. I have to unplug the ATV unit to get the TV to pick up the signal, and then, ATV unpairs from the remote, so I have to re-pair, and this is annoying at best. Yes, I could set Sleep to "Never," but...why? Shouldn't it just work?
Contemplating ditching the thing for a new one under warranty. Anyone else having the same issues? Once it's up and running it's fine. But it's really unreliable and buggy.

Why? because it would be an easy solution. Just set it to never sleep. It uses very little power.
Are you using a remote other than the one supplied?
I have never had this issue.

  • External monitor "No Signal" message

    MacBookPro mid 2010 with 250GB solid state drive. W80183G9AGZ
    Two problems, they may be related
    Randomly for some time the computer restarts with the message “Your computer has restarted because of a problem”
    This generates a crash report which I always send to Apple.
    (Unfortunately this computer does not support Apple Hardware Test nor Apple Diagnostics).
    Today the computer will not send a signal to the external monitor, ( a Samsung TV).
    I have carried out the following fault finding.
    DVI-HDMI cable plugged and unplugged several times in different order before and after -
    Restart
    Shutdown and then Restart
    Reset PRAM
    Reset SMC
    The same when using a VGA cable.
    With HDMI there is a “No Signal” message, with VGA the screen just stays black.
    Both HDMI and VGA previously worked flawlessly.
    Checked that the GPUs are switching correctly from the integrated Intel HD graphics to the NVIDEA GForce 330M. Previously, as soon as this happened, the external monitor desktop image would appear immediately.
    The presence of the external monitor is not being sensed, in “Displays” in System preferences no second display options are present.
    Questions
    Is the video problem definitely the NVIDEA GPU or could it be the computer crashing problem just getting worse?
    Is it possible to replace the NVIDEA GPU if it is faulty?
    Although the problem seems to be the same with both HDMI and VGA could it still be a problem with the HDMI cable?

  • Is there a way to contact apple support through instant message?

    I have an issue with iphoto, that when I choose a photo to email either to myself or someone else, it asks me to put my password (my password which I created for my apple account) and a message pops up which says my password is not recognizeable. Can someone please help me. I am new to the Macbook pro family and would like to resolve this. Thank you in advance Apple Community.

  • No signal message - Mac Mini - Samsung P2370HD - DVI-D cable

    I just received my new Mac mini and want to connect it via DVI-D cable to my existing Samsung P2370HD monitor. I have a DVI-D to mini-DisplayPort adapter connected to the Mac Mini and then a long (3-5 ft) DVI-D male to DVI-D male cable connecting the adapter to my monitor. I have checked all connections but the monitor is giving me a "No signal" message. When I unplug the cable from the adapter, the monitor gives me a "Check signal cable" message, so it seems as if the signal is not making it through the adapter to the TV.
    Can anyone offer advice? I really don't want to pay for a new monitor.

    My brain finally kicked in, and I was able to get the monitor to work by using the mini-DVI to DVI cable included with the Mac Mini and connecting that cable to my DVI-D (male to male) cable. I am now getting a signal to the monitor. Guess I will be returning the Dual Link DVI to Mini Displayport adapter as it was not cheap!

  • No signal message on HP 2010i using HPs500O Series desktop

    Hello,
         The issue that I am having is with the HPs5000 Series model # s5710f desktop. and HP 2010i monitor. The monitor displays the no signal message and then goes to sleep. I have tried to access the menu on the monitor to no avail. I have plugged the monitor with its own cables into another computer and it works fine. When the desktop is plugged into another monitor it does not work.  I was using the computer just the other day with no problems.  The other issue, I do not know if it is related, is that sometimes I have problems with it coming out of the sleep mode and have to manually shut it down. The only suggestion that I have seen is to open the desktop and clean it with a can of air. I was wondering if this would be my solution or if it would be someting else.
    Thank You

    HI massey76:
    I regret that you are having an issue. If the monitor works on another computer, then the monitor itself is functioning. I am sending information for both troubleshooting the monitor, and the computer. HP 2010i 20 inch Diagonal LCD Monitor support click here.  Computer Does Not Start (Windows 7) click here. I am unsure of what operating system you are running, so I just selected Windows 7.  If this has not resolved your issue, would you please provided me the exact model of computer you have.How Do I Find My Model Number or Product Number click here. What operating system do you have. Do you see any lights flashing or hear any beeps on start up?

  • No Signal Message

    Hello – I’m petsitting for a friend and have wrecked her TV. The TV was working fine when I turned it on but I inadvertently pressed a button on the TV remote (not the FIOS remote) that caused the TV picture to vanish and a “no signal” message to appear on a snowy screen.  I tried to set the TV to channel 3 using the TV remote but that did not restore service. Can someone please help me get this sorted out before she gets home and yells at me?  Thank you.

    My guess would be that you hit a button that changed the input that the TV is set for, to one that has nothing connected to it, or the device is turned off. Since remotes vary by TV brand, and you didn't identify the brand anyway, there is no way to tell you exactly what button to push. But most TVs these days have multiple inputs and a button on the remote labeled "input" or something like that; just just keep pushing it as it cycles through the various inputs until it reaches the one with the live connection.
    Having said the above, the Verizon FiOS remote has an "Input" button, in the lower left; mine is labled "A/V" on the button and "Input" below it. If your friend has the Verizon remote properly set up for the TV, that button generally will cycle through the inputs, just like the button on the TV remote would. You would need to hit the TV button at the top of the Verizon remote first so the signal goes to the TV, not the STB. I suggest you give it a try.

  • Samsung DVD Player "No Signal" Message

    Since we first bought our Samsung Blue-Ray Disc Player (BD-P-1400) it will play a disc for less than five minutes, and then the TV (Samsung Series 550) displays a "No Signal" message. The DVD player is still advancing the disc, but only the error message is displayed on the TV.

  • JBL wireless subwoofer signal now interferes with my Apple TV wireless signal.

    Ever since the newest software update, my Apple TV wireless signal interferes with my wireless subwoofer signal, immediately shutting off the music I am playing via Apple TV.  I have had my Apple TV since December 2011 with the same exact speaker set up and wireless internet and it worked fine - everything was compatible.  Ever since the latest software update (I updated my ATV software around the time when Apple released the 1080 HD Apple TV last month) my wireless subwoofer's signal interferes with the streaming wireless signal, immediately shutting down the music that's playing through ATV. 
    It is obviously the subwoofer because everything works fine when I switch the subwoofer off.  I have tried changing the channel of my woofer and the frequency of my wireless internet, but the problem persists. 
    My biggest frustration is that everything worked fine and was compatible up until the last few weeks.  Has anyone else experienced this?  Any solutions or advice?
    Thanks!

    It's actually your subwoofers fault. I have a Samsung wireless subwoofer and it uses 2.4 and 5ghz the same frequencies WiFi use, it is supposed to pick a channel that isn't used. It occasionally goes out for a split second.
    2.4 has channels like 1-12
    5 has like 5 channels something like 145-150 or something
    Your subwoofer is picking the same channel your wifi router is using. Wait I just say you said you checked your WiFi channel. Was your router on "Auto" channel selection before you changed it? Does your router support 2.4 and 5ghz? if so are both set to broadcast same network name and password?
    On a computer go to http://tools.meraki.com/stumbler and see how many routers are near you and what channels they are using. What kind of router do you use?

  • No Signal message on TV

    I'm gett ing a "No Signal" message on one of my TVs. I can change the input to video 1, video2, video3, but that doesn't do anything. Help!

    My wife is somewhat technicalyy illiterate and creates a situation like this all the time.
    Remotes are programmed to auto turn of tv and stb, she waves the remote in the general direction of the setup and the stb turns off but the tv doesn't get the power signal and then shows the no signal screen.  She pushes power on the remote and it powers the stb on and tv off so no picture, however she doesn't notice the stb is now on.  Next time she wants the tv on she  pushes power and it reverses it so stb turns off and tv turns on and again displays no signal.
    Perhaps your issue? if so make sure both devices are off by selecting tv device on remote before power off.
    Somewhat amusing but typically results in phone call to say the d....d tv has broken again.
    If this is in fact the problem, I suggest reprogramming the remote to turn on and off only the device selected, STB or TV. There is pretty much no value in turning off the STB as it consumes nearly the same power when turned on or off. I had the exact problem described by viafax999 and changing the programmng on the remote to separate the power on/off function fixed it completely, I never turn the STB off and just hit the TV button first before turning on or off the TV (takes a few days to get used to doing that, but after that, no issue).
    For anybody that wants to do that, the instructions are in the little booklet that came with the remote, or you can find the here:
