Mini DVI port stopped working

I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable. Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen.
I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself.
One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others. I’m thinking that this might be the culprit. However, I have tried to straighten it out using a safety pin and I’m not really able to do it.
Am I right to assume this is a hardware problem with my port? Any advice about how I might go about fixing this? Is there a way to repair the port without having to replace the whole logic board?
The Macbook in question is a 2008 Core 2 Duo running Lion.
Any suggestions at all would be much appreciated!

I think you may be right, it's a hardware related MiniDisplay port connector problem.
I think you can't fix it up by replace MiniDispaly port connector, however fix it by replace whole logic board.

  • Mini-DVI port not working: wear and tear?

    I had been happily using the mini-DVI port to play content on TV, using a DVI to Video adapter : plugging and unplugging probably twice a week.
    Now it seems to have stopped, abruptly: no signal at all is reaching the TV. (Adapter still works fine on my MacBook.)
    What are the chances of wear and tear damaging the DVI port? Is this a complicated fix? Any other thoughts? No recent upgrades or updates.
    "About this Mac" reckons it's mirroring fine, so it feels like a hardware thing. Many thanks in advance.

    Hello ewfelton
    It is very possible that the DVI port on the iMac has been damaged from wear and tear, as it's harder to get at than the MacBook.
    I would disconnect everything from the iMac, grab a clean towel and turn it face down on the desk. Then with a magnifying glass and light inspect the DVI port for a broken or bent pin. In the process of inspecting the port your SMC will also be reset, follow the instruction for "How to reset the System Management Controller" when your done.
    If the port seems OK and the SMC reset doesn't get it going use Disk Utility to Repair Disk Premissions and try it again.
    Your local Apple Store or local Apple Service Provider can replace a bad or damaged DVI port.

    Do not dismiss the possibility that the problem may be with the TV.  Based on what you have tried so far, an appointment at an Apple store genius bar is your best option.  The evaluation will be FREE and then you should be in a position to make an informed decision.

  • Dell XPS 15 l502x mini-Display Port stopped working after update.

    After the updates on the 11-10-2014 my mini-display port (which worked great previously and is part of the Intel Graphics) stopped working.
    Am running Arch 64bit with Slim + E19
    The symptoms are:
    1. Detects monitor from the laptop and xrandr throws no errors
    2. Enlightenment thinks the screen is connected and it appears in the screen setup as on.
    3. The monitor no longer recognizes that there is a laptop plugged in and just stays off...

    So I downgraded those packages and the kernel with no luck.
    I tried to get the HDMI working via Synergy... and failed
    I then tested the Display Port on Windows and it did not work there either - exhibiting the same symptoms as Linux - the OS sees the monitor but no data was transferred.
    So I ended up using one of my Display Link monitors at work... the USB monitors were ok, just an irritation with a flickering mouse.
    I hope it is the miniDP>HDMI adapter and not the port... very frustrated by this problem.
    I hope to test another adapter soon.
    I think as nobody else is experiencing this issue that it may well be hardware/firmware related.
    Hope there is a happy end to this post but not feeling so positive right now.

  • Ref GTX 680 2nd DVI port stopped working

    I'm having trouble with my GTX 680 second DVI port. It seems to register that it's connected, but doesn't have any signal.
    Now, it's worked perfectly for weeks... until I replugged it yesterday.
    My set-up (that used to work):
    >DVI port 1 goes to main monitor
    >DVI port 2 goes to second monitor
    >HDMI port clones DVI port 2 and goes to TV
    And this is what I did:
    >Unplug 2nd DVI port, use it temporarily for another machine
    >Replug hours later, not working
    And what I've tried:
    >rebooting
    >reseating the GPU
    >blowing dust out of the GPU
    >emptying my computer for power (pull out powerplug, hold power button for 30 seconds)
    >clearing CMOS
    >different drivers (both with and without clean install option)
    >plugging monitors into 2nd DVI port (no signal from any monitors)
    >tried DVI to DVI, DVI to VGA, and DVI to HDMI - nothing seems to work
    >tried older GPU, it worked (with both ports)
    >tried the onboard DVI port for 2nd monitor, works but then I can't "clone" it to my TV.
    It also doesn't seem to get any signal during POST and BOOT (tried both monitors).
    The monitor also appears in "Screen Resolution" but as "Available display output: on Intel(R) HD Graphics 3000," but it doesn't work.
    When I messed around with it, trying to get it work, it also had an option to "force VGA" or something like that - but that did not work either.
    Specs:
    >ASRock Extreme3 Gen3
    >2500K
    >8gb Samsung Green low profile ram
    >MSI GTX680 with ref cooler and EVGA backplate
    >Corsair AX750
    >OS: Windows 8 x64 (although I doubt the operating system is an issue, since I don't even get output during POST/boot).
    I've tried searching, but to no avail. I've found people with similar issues, but none that managed to solve it. Example:
    >forum-en.msi.com/index.php?topic=142971.msg1066807#msg1066807

    I'd RMA the card as it sounds like the 2nd connector is broken and is not working guess it wasnt soldiered in place properly and its cane away on one of the connectors!!
    Sounds probable, but if you look at the first link I posted where other's have similar issues (https://forum-en.msi.com/index.php?topic=142971.msg1066807#msg1066807) he tried swapping his GPU and it did not work for him. It might of course still be that the connection is just bad on my GPU and something else for him.
    I'll wait a while and see if other's can come up with some good suggestions. If not, I guess I have to RMA it.

  • Mac mini thunderbolt port stop working

    Good night.
    First, I apologize for my English.
    I have a mac mini (2011 model). Two days ago there was a power outage and the mac shut down. After turning it on, it failed to recognize my TV connected through the Thunderbolt port (with a adapter THUNDERBOLT -> HDMI).
    When I disconnect and connect the adapter into the thunderbolt output, the screen flashes (as if he had recognized the second monitor). However, the monitor does not work.
    Some Details:
    1) In the monitor settings, only the main, connected by HDMI is detected;
    2) On the "System Information" screen, the "Thunderbolt" item appears to state “no device connected";
    3) I've done the reset PRAM / SMC.
    Can anyone help me? Does my thunderbolt output fried?
    Thank you,
    Mateus.

    I would try a different HDMI cable and then a different Thunderbolt/MiniDisplay Port to HDMI adapter.

  • Mini dv port not working

    When the mini dv port stops working, is there anything software wise that might resurrect it?  This is on a refurb (from Apple) 2008 MBP, and the port was never actually used for anything until this past week, and it is not working.  Could it be software related?  Suggestions for repair?  I've looked everywhere but it seems this is a very uncommon problem.

  • My mini DVI port suddenly stopped working! :(

    Hi! I hope everyone is doing well. I bought a mini DVI port to connect my macbook pro to the projector. It was working perfectly until yesterday, it suddenly stopped. I mean the laptop won't show on the projector. when I play around with the port and the cord and move them, they show a blue screen like the one that appears when the laptop detects a projector but NOTHING happens then. The laptop normal screen comes agian! I know that there is a problem maybe with the cord or the laptop mini DVI slot! How can I know where the problem is? I don't wanna buy a new port then the problem appears to be from the laptop.
    Peace and thanks in advance!

    They tested it with their cable and mine.  First off, they connected an external screen to the mini port.  With their cable and mine, they could not get the "detect display" to see the screen.
    Then they rebooted the machine from an external drive/os and it immediately recognised the external screen.
    So the diagnosis was that it was a software thing.  I asked them if they could refresh the drivers or clear the settings but they were pretty unhelpful - did not want to go there.  Basically they said rebuild the OS from the ground.
    I find this somewhat frustrating as surely there is some soft settings that can be done without rebuilding.  Are there any "preferences" or similar types of things that I can delete out of the library file.....?  (I am not a Mac tech guy - I am a user.....).

  • Mini DVI Port has stopped working

    Hi
    I am using a fairly new MacBook Pro 15".  Up until recently, the DVI port was working fine with an external monitor.
    Now all of a sudden, it does not detect an external display at all.
    I am using the Apple Mini DVI port adaptor and the DVI connection to the monitor.  (I have two similar monitors and my wife's machine works fine on both of them so I don't think its the monitor.)
    Running 10.6.8
    Anyone able to help?

  • Is it possible for a mini DVI port on the graphics card to stop working while the DVI port works fine?

    I have a 27 inch cinema LED display that will not work when I plug into a Mac Pro (10.6.8) mini dvi port. But it will work fine on another Mac Pro with the same system and other Mac Pros with Lion and Mountain Lion. I can get a 20 inch LCD monitor to work in the DVI port on the mentioned problem Mac.
    I've ran all software updates and troubleshooting utilities.

    Real, Welcome to the discussion area!
    Sorry to douse your enthusiasm but that is NOT a mini-DVI connector. It is a mini-VGA connector.

  • HT4951 Can i use a Thunder bolt display with an iMac from the mid 2009 ? Would it work if connected to a mini dvi port in a scaled down mode or is it compulsory to have a thunder bolt port ?

    I have a mid 2009 iMac that doesn't have Thunderbolt display, but has a mini-dvi port.
    Will the Thunderbolt cinema display 27" still work when connected to this mini-dvi port ?
    I thought it would be better going for a thunderbolt display monitor rather than the older version, so when i upgrade my machine in the future it stays compatible.

    No.  A TB display can only be connected to a TB source.

    As indicated in that artical a displayport device can be connected to a TB source.  But that is not your situation.

  • I cannot use any external monitor, it appear like the port doesn't work , i'm using the mini-dvi port with a VGA adaptor ,

    I've always used the port normally with different monitor but by a couple of weeks it appear like no signal come out.
    Does Anyone knows what can i do ? i.e. How to check or reset the Mini-dvi port ? or if there's any key on the keyboard that can habilitate it or not ?
    Any Help will be appreciate
    Thanks

    Welcome to Apple Support Communities
    You don't have to do anything to make the port work. Reset the SMC > http://support.apple.com/kb/HT3964
    If it doesn't work, try with another monitor to see if it works or another cable. If you haven't got another display, take the MacBook Pro to an Apple Store or reseller, so Apple will test the port and see if it works correctly

  • Is that actually a mini-DVI port on my G5 iMac?

    So I can't seem to figure this out...
    Is the Mini-DVI connector on the back of the G5 iMac (2 GHz, pre-camera or remote) a jack (male) or a port (female)? I bought one of the Apple mini-dvi -> S-Video & RCA adapter cables, but the mini-DVI end seems to be identical to the machine's connector, and thus they won't mate. Did I just buy the wrong adapter? I doubt this because Apple would have no reason to even make such an adapter, as all its models of computer should have the same sex of plug built-in, and thus no need for a choice between mini-DVI (M) -> whatever versus mini-DVI (F) -> whatever.
    Any help or advice?
    The mini-DVI connector on the cable has a rectangular metal rim with rounded corners on the bottom. Inside that is a C-shaped (like 3 sides of a long, low rectangle) plastic element with 8 axially parallel contacts on each of: the outside of the top of the C; the inside of the top "..."; the inside of the bottom "..."; and the outside of the bottom "..."; this totals 32 contacts.
    This doesn't appear to work with the port on the iMac. The whole in the machine's external frame doesn't immediately contact the outer metal rim of the jack; it appears there's enough space for the sleeve of the connecting plug to slide in betweeen them. Also, the rim seems slightly more rounded/angled than that of the adapter above. Thirdly, the plastic center element is a wide, low rectangle with barely rounded/angled bottom corners (4-sided versus the adapter's 3-sided/C-shpaed central plastic element). Lastly, there are 14 (not 32) contacts in a staggered (not axially parallel) layout which only exist on the inside (not the inside and outside) of the center plastic element.
    So what's the story? Do I actually have a mini-VGA port (as in some of the laptops which were advertised as having a mini-DVI port but which were actually mini-VGA)?
    Help! I need to get split screens going to start building the audio>visual>audio interface I need for a major installation/performance piece I'm working on.
    Thanks,

  • Does the mini DVI port cary audio if using a Mini-DVI to HDMI Adapter?

    Hello everyone,
    I've heard it is possible for a DVI port to transmit audio data to a HDMI connection if a DVI to HDMI cable is used, which will allow the sending of both audio and video to your TV. see: http://en.wikipedia.org/wiki/DigitalVisualInterface
    I'm assuming this is not possible using apples mini DVI port, but just wanted to check to make sure. My main goal is to get surround sound out of my powerbook. To do this by simply adding a Mini-DVI to HDMI Adapter would be GREAT!

    Hi Jonathan,
    I'm assuming this is not possible using apples mini DVI port
    Yup, no audio, unfortunately. The audio will have to transmitted separately via the analog audio output.

    Hi，
    So switch a LAN card fix this issue...seems a compatibility issue or maybe some packs or programs you installed recently cause this issue.
    Have you manually check the network adapter driver from the PC's manufacture website? sometimes, it will be a time delay before Microsoft push out the driver update.
    Check if issue exists in safemode with network, this mode will launch Windows with limited sets of files and drivers. 
    if you have a restore point, restore the pc to a previous point at which the pc is functioning fine.
