No video signal toshiba tv/dvd hdmi

fios guy set up my fios tv with samsung tv last week. everything was fine.
I got a new toshiba tv dvd combo today. have HDMI plugged into HDMI 1. When I power on the TV (and HDMI 1 is selected) it shows "No Video Signal". (audio is fine)
I need to un-plug HDMI and then re-plug HDMI to show the video. When I turn off the TV and then turn it back on. Same thing happens "No Video Signal"and I again need to unplug HDMI and then replug to get the video...
any suggestions? thanks so much!

The key problem is that the HDMI "standard" isn't quite standard yet. So you have two devices from different manufacturers trying to adhere to a common method that is still open to interpretation. Don't you just love bleeding-edge technology (5 yrs old anyway)?  I have some similar diffulties with one of my TV's, a Panasonic about 3 yrs old, and have resorted to using the component video cables instead of the HDMI cable. I really cannot see the difference in the picture or sound, so that method works fine for me. I suggest that if you can't find a workaround, do the same.
To get as technical as I can with this, what's happening (with bi-directional digital HDMI)  is that the set-top box is "talking" to the TV and trying to decide what to do to provide the right, if any, output. One of many things being "discussed" by the two devices is for example whether you are trying to illegally record anything. The Verizon box asks the TV to supply a proper response and if it cannot, then the box shuts down and won't send anything. The TV HDMI design must be able to supply the correct encoded reply according to the standard. If it isn't quite exactly what the box wants to see, then "lights out". Don't you just love the digital age? The analog HD component video cable set (not to be confused with composite video) has no provision for any return response (it's one-directional) so it's use is not a problem. The Verizon box does not expect any response in that case and goes on happily content to send its video out to whatever is receiving it. That is why many not-quite-legal digital recording setups use the component video cable interface instead of HDMI. Good luck...

    Hello Yusuf,
    I have a PXI system with a PXI-1411 and IMAQ Vision and NI-IMAQ. I'm using this card to acquire the video signal from a DVD.I'll like to develop an application with LV able to check frame by frame if my received signal is arriving in good conditions.This application should be able to detect if there's some frozen picture effect or if the DVD unit shows are incorrect pictures. I have no idea how to launch this project and if it can be done. Could you give me some idea or tell me the link of somewhere to find this? By the way, I have a PXI-8176. Thank you very much.

  • Toshiba 32C120U "no video signal" from my Mac Mini using HDMI to HDMI.

    My Toshiba 32" 32C120U is not getting video signal from my Mac Mini. I bought the Mini for my son and this is his TV. I have hooked up the Mini to my older 22" Toshiba and my 56" Samsung with the same HDMI cable and it works great on both. What the heck is wrong with my son's 32" Toshiba? I did update the firmware on the TV and the Mac Mini has been completely updated as well.
    I have also tried both HDMI 1 and HDMI 2 ports with his Xbox with success, so both ports work. I have also tried both ports with the Mac Mini and there is "no video signal" on both ports. I noticed that when I hooked up the Mini to the other TVs it automatically selects the best video setting, so there is obviously some communication that happens between the Mini and TV, but that is not happening with my son's TV.
    Any suggestions would be greatly appreciated.
    Thanks in advance,
    John

    I solved my issue . . . returned the Toshiba for an Insignia . . works great.

  • 46SL412U Sudden No Video Signal for all HDMI Ports

    My daughters and I were playing the Wii U tonight on our Toshiba 46SL412U LED TV when suddenly the picture when black and the No Video Signal message came up.  I changed out the HDMI cable thinking the cable went bad, but still no picture.  I power cycled the TV, still nothing.  I am also not getting any picture with any of my other devices that are hooked up via HDMI port (BluRay player, Chromecast).  Oddly, the REGZA-LINK still recognized that the BluRay and Chromecast are plugged in and switches to the correct input when I power either of them on, but i'm still getting the No Video Signal message.
    Is there a setting I've missed that suddenly changed, or did all of my HDMI inputs suddenly go bad?  What can I do to fix this issue?

    To check the Graphics card's funtionality you may go to BIOS menu and see if is it listed or not; if yes, then it's working, and you may have to check the video/HDMI cables.
    Try to boot the PC without connecting any device other than monitor, power cable, mouse and keyboard.

  • Brand New ATV3 - No HDMI video signal.

    Brand New (2013) ATV3 - No HDMI video signal when plugging it in to my TV (Toshiba 52" LED).
    Ive tried 3 different HDMI cables in 3 different HDMI inputs in various configurations. Still no video.
    Ive tried power cycling ATV and my TV, and changing resolutions using the Apple remote - Still nothing.
    Ive seen serveral forums offering many but unhelpful options.
    Yes, my TV is set to the same HDMI input as the HDMI cable is plugged into.
    Please help?

    You tried difference HDMI cables, different HDMI ports, cycled the ATV, confirmed optical audio output works. Do you have another HDTV to plug in and test? If ATV video fails to appear in this case, I would say that this would confirm the Apple TV HDMI output is broken given the extensive troubleshooting you have already performed. In my opinion, this would completely isolate the diagnosis as ATV malfunction. Did you purchase it via Apple or Third party? Apple will replace the device within 14 days no questions asked, or service it within one year. If third party, contact them regarding your coverage.
    How long is my Apple TV covered by Apple’s warranty?
    Apple's Limited Warranty for Apple TV covers your Apple TV for one year. Warranty service for eligible repairs is available at no charge for twelve months from the date of original retail purchase ("date of purchase").

  • No Video Signal new DVD connection to LCD TV

    I just got a new SD-V296KU DVD/VCR combo and connected it to a 40FT2U LCD TV player I got last year. I followed the directions in the setup guide and owner's manual exactly, but I get a "No Video Signal" error on the television. Audio does work. I originally tried with an external tuner too, but still doesn't work when TV/DVD connection only. I've tried switching the connections around (standard yellow/red/white wires) and no change. Obviously everything on the "support" website has the same instructions and can't talk to anyone who can help....can somebody here please set me straight?

    With the change to Colorstream on the TV, I now have color DVD and audio...thanks, Peter. However, I still only have audio for VCR playback; even when the selection is set to 'VCR', the screen only shows as "Welcome DVD - Toshiba". This also means I cannot enter VCR menu setup for setting clock, etc
    Just to clarify the original quick posts, I added since I could not get assistance on phone and wanted to make sure whoever did see this was updated with where I stood. I originally hooked up r/y/w cables per directions in guide, but change to the green/blue/red using the white and red from other for audio. I actually posted a somewhat more detailed message later the same day (as my originals here) on the DVD board, but that apparently was taken down. Here's the exact connections:
    40FT2U LCD: g/b/r- green = Y/Video, blue = PB, red = PR; w/r/y- white= L/Mono, red=R; yellow = bottom on Digital Audio Out; RF modulator cable in Ant/Cable box.  These hook to...
    SD-V296KU DVD/VCR combo: g/b/r on 'Component Video Out' in order Green top, blue middle, red bottom; w/r/y on 'DVD/VCR Audio Out' in order white top (L), red middle (R), yellow bottom (Video Out); also have w/r/y on 'VCR Audio In' in order white top (L), red middle (R), yellow bottom (Video In) leading to...
    Zenith external tuner: w/r/y - white (L), red (R), yellow (video) and RF to TV plus separate coax to antenna
    I am happy about the DVD, but this combo is no good without VCR too. Your knowledge sharing is appreciated.

  • [Solved] A75A-G35 gives no video signal over HDMI, resolution over DVI limited

    Hello community,
    following problem: I have been using my A75A-G35 board with an A4-3400 Llano APU, the APU has been connected to a 19" BenQ FP91GP monitor via a DVI cable. I got its maximum resolution of 1280x1024 with no issues.
    Now I have purchased a 24" Dell U2415 monitor with a maximum resolution of 1920x1200 and wanted to connect it to my computer. However, I got stuck:
    1. I get no signal whatsoever using the HDMI output and a HDMI>HDMI cable. I have tested a different computer and connected it to the Dell with the same cable successfully, so the cable and the monitor should be fine.
    edit: Disregard the following as the problem with the DVI cable appears also with the other computer. The problem is therefore just the fact that the HDMI output of the board doesn't work!
    2. I get a signal with a DVI>DVI cable + DVI>HDMI adapter. I can access the BIOS, the boot manager and see the boot screen, however once the desktop should be displayed the screens turns black and the monitor keeps switching to standby and back on again, the screen staying black all the time, however. But before installing the driver package (for chipset and video, downloaded from the MSI website), I could see the desktop with a resolution of 800x600. Also, if I boot into safe mode, I can see the desktop and increase the resolution up to 1280x1024. Higher resolutions up to 1600x1200 are available, however selecting any of them results in severe screen flickering.
    3. If I boot my Linux install, I have almost the same behaviour. I see the boot messages but then the screen turns black when the desktop should appear. However, if I connect the old BenQ monitor to the VGA port, I get a signal on both screens, however both screens have the resolution 1280x1024 and I cannot increase the resolution of the Dell, because if I try to, the screen turns black again. Lower resolutions than 1280x1024 are possible, though. Note that the "second monitor trick" does only work with Linux, with Windows I get only a black screen on both monitors.
    As a side note, the DVI cable I'm using is a DVI-D single link, so the maximum resolution it supports is actually exactly the resolution of the Dell, 1920x1200.
    Thanks for any hint,
    Photon

    your welcome! 
    when you said your problem and the symptoms I thought that board sounded familiar as alot of people when it first came out that we had to explain that to them so I had a look and yes it had the jumpers to switch ports for its digital display display signal to be routed to another port so i thought that was the cause!
    have fun with your board now you have it in HDMI mode!

  • Set DVD to Sleep Video Signal Sooner

    Greetings!
    PROBLEM:
    My DVD project is burning in my LCD HDTV screen.
    QUESTION:
    Is there a way to make the DVD shutoff its video signal after a couple minutes of no activity (and override the player's sleep setting)?
    I have two menus and three movies.
    WHAT I'VE TRIED:
    The forum search here seems to have changed, it searches the whole site (what's up with that?) so that was no help.
    Menu pallet> General tab> End (set 2min for audio)> Duration (set 2min)> At End: Time Out (set 1sec)
    The player led counter stops after the 2min as expected, but the menu stays on screen too long...

    There is no command in VM of DVD player to go into sleep mode, however there is "exit" command to stop playback.
    To use it you'd need to redesign your navigation scheme. For example you could make your main menu to automatically play the first movie after the menu itself have been played 3 times. So after 6 minutes of menu the movie will kick in, preventing your screen from burning-in.
    The end jump of the movies would be set to another menu that times out to a script which would include the exit command. This will end the playback and after a defined time your player will go into sleep mode.

  • Need to split video signal to both HDMI and VGA

    I am hosting an event and the venue has given me a really tough challenge. I need to send a video signal from my Macbook Pro 15"(the highest spec, latest model) to a projector that only accepts VGA and to an A/V system that only accepts HDMI(this A/V system broadcasts the signal to several flatscreen TVs throughout the venue). Here are my two ideas, can anyone tell me if this will fail and if so, are there any other solutions?
    Idea 1: Use a mini-display to VGA adapter, split the VGA cable with one VGA cable going to the projector, and the other VGA cable going through a VGA to HDMI adapter to the A/V system
    Idea 2: Use a mini-display to HDMI adapter, split the HDMI cable with one HDMI cable going to the A/V system and the other going through an HDMI to VGA adapter to the projector
    Idea 3: Rent another projector that accepts HDMI, use a mini-display to HDMI adapter and split the HDMI cable, with one going to the projector and the other to the A/V system(this is the most expensive option and I want to avoid this if possible)
    The event is tomorrow evening, and I need to buy these cables today if possible. Would love to hear any ideas, thanks!!!

    Yes.  All video and audio outputs are always active.

  • No video signal when connecting Blu Ray player

    I have a new blu ray player and HDMI cable. It will play just fine when connected to little cheap TV but my large Toshiba will just show No video signal when I try  to connect it and use it. I have tried everything, read the whole manual, searched online help, called the support phone number which just directed me back to the online support. Nothing has helped.
    Also when using my old DVD player with the 3 component cables, I never get any color, just black and white picture. 

    The TV likely has a shared video input. You need to tell it in the settings whether you're using a composite or component device. If you have a composite device connected and the TV thinks it's a component device, it'll show up in black and white. What model number is your TV? I'll tell you change the setting once I know what TV you have.
    Also, to what specific port is the new Blu-ray player connected?

  • No video signal after changing resolution...

    Hi guys...
    I have had this issue in the past.
    I have an ATI Radeon 9000 on a G4 Quicksilver. I have had it hooked up, for the last few years, to my Toshiba Regza 42" LCD utilizing a DVI to HDMI connector.
    Recently, my wife and I have decided to sell the Quicksilver so we flattened the hard drives and did a clean install of Leopard.
    From there, I upgraded Leopard from 10.5 to 10.5.8 and then went to change the resolution to 800 x 600 as I had in the past so I could test out VLC's speed. The signal went out...and never came back.
    Not panicking (I had a prior issue on this board and it was fixed), I restarted in Safe Mode. However, when I went to Safe Mode, the resolution I wanted was already chosen and when I clicked on it again and restarted OUT of Safe Mode, I'm STILL getting "No Video Signal" on the Regza.
    I've also noticed that while 800 x 600 works (in Safe Mode), you cannot restart into that resolution AND it's surrounded by black bars rather than filling the whole screen like it used to. I don't get this.
    I've been told that I may have to erase the entire set of drives again and install only up to 10.5.6 or lower as this is an Apple resolution issue.
    I REALLY don't wanna do this.
    Is there a way to fix this issue?
    Thanks!

    1920 x 1080 and 800 x 600 so far. I haven't had the guts to try anything else. I lost Safe Mode by going to 640 x 480 once as well as 1024 x 768.
    The issue is that the Regza can be set to the first to in Safe Mode but will not reboot to these resolutions when booting normally.

  • Video signaling problem caused by 1.9, 2.0 BIOS (pointing out a BIOS problem)

    Hi, i have a problem with the video signal. At random times when i boot up my computer, the computer would power up but there is no signal to the monitor. there is no hdd activity (via the hdd led) and nothing seems to be happening just that the fans are whirring. i have to unplug the computer then plug it again then turn it up again which sometimes repeats the problem. This is very irritating! So i did a little bit of troubleshooting:
    1. I changed video cards. I used a SAPPHIRE ati radeon 9600XT fireblade and a LEADTEK GF4 ti4200. Both cards were causing the same problem and when i used both cards to another computer, there is no problem. = NOT A video card problem
    2. used differnt kinds of drivers Cat 3.10, 4.10, 4.20 (omega and official) does not seem to do anything (which also i believe the drivers are OS dependent and its the bios of the vid card that starts up the vid card)
    3. upgraded from 1.9 to 2.0 BIOS. still the same problem
    4. reverted from 2.0 to 1.7 BIOS. the problem ended.
    BTW, the board is 865PE-Neo2 - S. on a Intel 2.6Ghz C, 512MB TwinMos ram with m-tec chips, 80gb hdd, enermax 300w psu
    so ive' solved the problem, and i just wanted to point out that there is a problem with 1.9, 2.0 BIOS. (havnt tried the 1.8 tho)

    Wish I had seen this thread 2 weeks ago, but you did save me from buying a new graphics card.  That was the last step (before chucking this mobo completely) in my attempts to fix the same problem.  It didn't bother me too much, except I also couldn't get any DVD player (tried 3) to work.  Would boot sometimes and at others gave a blue screen video error.
    Flashing to bios 1.7 was the only thing that fixed it.  Tried different memory, updating software, various combinations of drives, etc.  For the record I tried bios 1.8, 1.9, 2.0, and 2.1.  Not sure what about those updates causes problems but there definitely is something wrong.
    Thanks.

  • Video signal lost on launch of iTunes (after "update")

    I just (foolishly) "updated" to the most recent version of itunes.  And, surprise surprise, a headache has ensued.  I am using a mac mini hooked into a TV via HDMI (the setup is mac mini ---> receiver ---> TV).  After the itunes update, Weirdly, when I launch itunes, the video signal gets lost.  The application appears to start without any problems at first, but 10-20 seconds after launching, my TV goes black.  I've never encountered a problem like this before (I've had my mini hooked to my TV in this setup for some time.)  Any thoughts on how to try to address this issue would be greatly appreciated.  (If only I had this computer on time machine, I would go back an hour and all my problems would be solved.)

    I had the same problem after installing Snow Leopard.
    But now it seems magically fixed after updating to 10.6.2
