No light coming from the LED panel

Hi,
I had to remove the LED panel on my X220 and when I put it back, the light of the LED is no longer working. The panel remain dark but when I put a flashlight behind I can see the displayed image.
I tried the to put a new flat cable, but this didn't solve the problem.
My question:
Is there any fuse that can be changed?
Is there a way to bring power to LED panel?
Regards.

Hi
Welcome to community
I am suspecting the  LCD cable causing the issue . You can try by swapping the parts
Hope This Helps
Cheers!!!

  • Red light coming from the headphone port

    does anybody know why there is a red light coming from the headphone port.
    This is after i reformatted 
    Thanks

    This is perfectly normal. You can run an optical digital out this way. You need a mini-toslink adapter like this:
    http://en.wikipedia.org/wiki/Mini-TOSLINK
    Then you can set the digital out as default (instead of Speakers) to run audio to a surround sound reciever via optical fiber.

  • Internal speakers suddenly will not unmute.  My headphones work, and there is a red light coming from the headphone jack

    I put my volume on mute a few weeks ago, and I don't know if I have used it again since then or not, but now the volume will not unmute.  There is a red light glowing out of the headphone jack.  Sound through headphones works.  I've tried updating and restarting my computer.  Help?

    No, not forceful - gentle.
    A PRAM-reset might also help:
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Immediately press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until the computer restarts, and you hear the startup sound for the second time.
    Try this a few times.

  • Is the red light coming from the top on my iphone normal ?

    Red light on top of iphone !

    That would be the proximity or brightness sensor and is normal to see in extremely dark environments.

  • Red light coming from my audio output, speakers not working

    I read somewhere about wiggling a toothpick around in there, but that didn't work, any other ideas.
    This happened after I had a 1/4 to 1/8 converter plugged in there to use a little mini amp.
    I've lost the use of speakers.
    headphones work fine
    I think the optical input is still reading as if something is plugged in. Not sure if there's something in my system I need to switch, or if I need to take it in, have the jack opened up and replaced

    Just to rule out the obvious make sure your mute switch (F3) is not on. If your 'switch is stuck' you would see a red light coming from the headphone port.
    Double check your Sys Prefs - Sound settings ...if things still are not working you might try a SMC reset followed by a Pram reset that would restore your orig. settings.

    My remote for my Apple TV just stopped working and I have tried putting in a new battery, re-pairing the remote, resetting the device by unplugging it, and I checked the infared coming from the remote is working. The light just blinks at me 3 times what else can I try to fix it?

    Have you tried unpairing the remote? You do this by pointing your remote at the Apple TV and holding the MENU and Left buttons down together for 6 seconds.

  • HT2494 the sound won't work on my Macbook pro  the headphone port actually has a red light coming from it

    Can not get sound on my Computer.  The headphone port actually has a red light coming from it.  Help

    Insert a headphone jack and remove it and see if the light goes out. The red light indicates the switch didn't switch from head phone to your Mac's speakers. Some folks have actually used a match stick to undo the switch.

  • I have a macbook pro 15 retina - when ever I connect to bluetooth speaker, I get this loud noise coming from the speaker - if I turn bluetooth off, the noise is now coming from the macbook speakers

    I have a macbook pro 15 retina - when ever I connect to bluetooth speaker, I get this loud noise coming from the speaker - if I turn bluetooth off, the noise is now coming from the macbook speakers & stays until i restart.

    Hi John. Thanks for that input. At Step 6, after clicking "Next" I get a window telling me my OS version is unsupported and the installation may not complete. I am prompted to go to Canon's web site to "Check Latest Info".
    I've had this window on previous attempts and from Canon's web site I downloaded two drivers as follows
    - ICA Driver V4.0.0
    - Canon IJ Network Tool V4.5.0
    I'm not sure if these are the correct / complete drivers I need for this install or not.
    I continue to follow all the steps. At step 9 I click "Wireless Set Up using USB" amd get a License Agreement (a little different than instructions)
    I click "Agree" and it goes to a Setup window with two progress bars showing the installation. I've not been prompted to connect the USB?
    After the Setup window is done, I am then prompted to connect the printer via USB. I connect the printer and click on "Redetect". It is not detected.
    I then try following the Canon on screen instructions for connecting to the wireless LAN amd enter the password. It searches and indicates "Connecting" on the window, but it never connects and the blue light just blinks
    So, at this point I am stuck??
    Thanks

  • Recreating the light sensor from the complete sensor template

    Hi, new to this board and a total newbie to LabView. Tried recreating the light sensor from the complete sensor template for use with similar functioning homebrew sensor. Turned out to be quite difficult. Anybody around here thats already done that or some similar sensor block that you could share as a template to examine and modify? If the original light sensor block would not be locked I would have started from that.
    I also wonder if ther is any way to get digital line on pin 6 to behave as digital line on pin 5 does with the "generate light" function (would be great for making a color sensor with to different colored LED:s as illuminationMessage Edited by PTP on 05-10-2007 03:11 PM

    More or less trying to do a copy of the original light sensor block included with the Mindstorms software by starting out with the complete sensor template in the LabView Tooolkit (I have the student version 7.1) Planning on adopting it for my own analog sensor application later on (using the light out on pin 5 for another on/off application). Can´t remiport the version in the Mindstorms software so I have to start out from the template. My application of cause works with the Mindstorms light sensor block too byt it would be cool to make it from complete sensor template with the toolkit using my own scaling algoritms etc
    Michel Gaspari has a version made from the simple sensor template here:
    http://www.extremenxt.com/cdssensor.html
    But I would like to get the terminals for scaling and logic termial with a cut of value into the block too

  • My sound coming from the internet on my MacBook Air is not working!

    I bought this MacBook Air a month ago is the new one, everything was working well but suddenly the sound coming from the internet stop working.
    My computer sound is working perfectly is just when I want to watch a video or listed a song from youtube talk on skype isnt working at all.
    When I press the volume button i can hear it.
    Can someone tell me what can it be?

    Hopefully one of these steps should solve the problem.
    1. System Preference > Sound > Output > Internal Speakers
        Highlight  Internal Speakers / Headphones
        Make sure Mute is not enabled.
    2. Remove the headphone.
        If you see red light in the headphone port, plug the headphone
        in and out of the port 5 or 6 times to flip the microswitch inside.
        Sound output may be stuck in the digital mode.
    3. Reset SMC.     http://support.apple.com/kb/HT3964
        Choose the method for:
        "Resetting SMC on portables with a battery you should not remove on your own".
    4. Applications > Utilities > Audio MIDI Setup
        Audio Devices window
        Side Bar
        Click the Built-in Output.
        Under Mute any of the boxes checked? If so, uncheck it.

    I recently migrated my MacBook from 10.5.8 to 10.6.8, using the Snow Leopard CD I purchased from Apple. Since then I have noticed a strange ozone smell coming from the MacBook in the area where the hinges are to open and close the unit. I was told by Apple that it probably is not serious and is coming from the fans in the MacBook. It is true that the smell/odor is more intense when the fans are working. Apple said I should take the MacBook to an Apple Store to have the hardware checked out. Everything seems to be working correctly. I am backing up automatically wirelessly to a Time Capsule, which I had not done until recently, although I had purchased the Time Capsule in 2009. I have not noticed this odor before. Does anyone suspect something more serious that may be going on?

    You may be smelling it because with the new OS the processor is having to work harder causing it to get hotter then it would with the other OS.  I can't say there is nothing wrong, but what could be happening is just that, it's getting hotter so the fan is spinning faster and moving more air so you are getting more of the smell then you would before.  I would still continue to back it up, and take it to the Apple Store at a Genius Bar and have them look at it to make sure.  Was the computer ever in a smoky environment??

  • How do you remove items from the assets panel that are duplicated?

    How do you remove items from the assets panel that are duplicated?

    If you add an item to a slideshow, you'll usually see 2 entries for that image in the assets panel - one represents the thumbnail, and the other represents the larger 'hero' image.
    It sounds like you may have added the same image to your slideshow twice. You can select one of the hero images or thumbnail images in your slideshow and use the delete key to remove it. Then the extra 2 entries in the assets panel should disappear.
