Humming from Laptop Screen

Hi guys,
I have had a L300D 21Z for about 5 months now and just recently noticed it has developed a kind of humming/Buzzing for the LCD screen.
When the laptop display shuts down the sound goes away so I know the screen is the culprit..
Anyone experienced anything similar? Any way to remedy this?
Thanks in Advance!
Martin

Depends on whether you can do it yourself or not.  An inverter is not very expensive. 
See http://www.irisvista.com/tech/ for dissaembly instructions and check some of the repair guides at the bottom of the page.

  • Portege R500 - Switch view from laptop screen to LCD projector

    Hello - new here, urgent request. We are having a meeting and I am using the Portege R500 for the first time with LCD Projector which is also a Toshiba.
    How do I switch the view from the laptop screen to the projector screen? I thought it was Function F5 (Fn F5) but it isn't working.
    Can anyone help?

    Hi
    Yes, you have to use the FN+F5 to switch to the external monitor or to external projector, etc
    Firstly you have to connect the notebook with projector while the both devices are off.
    After you have connected the projector you could power up the notebook.
    Then try to switch to external projector using the FN+F5 key combination

  • AppleTV loses streaming connection from laptop - screen-saver/sleep?

    Hi,
    I am trying to watching movies saved to my laptop by streaming them directly via AppleTV (initiating through Apple TV interface).
    At first, it seems to work fine - the streaming works - but after 15 or 20 minutes, the connection drops and the AppleTV appears to have lost the link to my iTunes account (it asks for me to set up the iTunes account details new).  When I reawake my laptop from sleep and reaccess the AppleTV interface, it 'finds' the link again.
    I have experimented by disabling the screen-saver by placing the cursor in the bottom-right of the screen, and the problem does not occur.  Nevertheless this is not a proper fix for the problem.
    Can anyone help me find an automated way to stop the laptop from going to sleep or activating the screen-saver when streaming movies from AppleTV, but not when the laptop is not being used?
    Thanks in advance for any help.

    I have the same issue with my Mac Mini.. Ive gone into the energy saver settings and changed computer sleep to never as well as the display sleep to never but can not get it from disconnecting.,

  • Laptop screen not getting locked on close lid or resume from suspend

    I am using kde 4.4 rc2 atm. My laptop screen is not getting locked when I closed the lid or when laptop resumes from a suspend to ram.
    It used to work correctly before I installed acpid(before that I just had the acpi client package installed.) Power Devil used to handle everything correctly.
    The power devil settings already says, Lock screen on resume and I have added Lock screen as action for Lid close for performance profile.
    Is there any way to fix this. I want to make laptop screen lock when I do lid close or resume from suspend/hibernate.

    Suspend has always been problematic under Linux. It seems to be hit or miss for the most part, but here are some things you can try:
    Use an LTS kernel, tuxonice, pm-utils, etc. See Suspend and Hibernate
    Try a different graphics driver
    Tweak the driver module parameters or build your own driver.
    Unfortunately I don't have experience with the radeon driver, so I can only give you ideas.

  • Why does an image in Preview disappear when I move the window from my laptop screen to my external monitor?

    I have an external 23" Cinema display connected to my MacBook Pro. When I open a file in Preview, moving it from either screen that it was originally on (laptop>LCD or LCD>laptop), the image disappears or "blanks". Only zooming in on the image will re-display it. Any ideas?

    Still investigating this problem.

    Hello chrispyw,
    If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
    OS X Yosemite: Adjust your display’s resolution
    If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
    Apple computers: Troubleshooting issues with video on internal or external displays
    Reset the system
    You can reset the Mac's parameter RAM and SMC.Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Thank you for using Apple Support Communities.
    Regards,

  • HDMI cable connected from TV to Mac, what do I click on to get the movie on my laptop screen to show on my TV screen?

    HDMI cable connected from TV to Mac, what do I click on to get the movie on my laptop screen to show on my TV screen?

    When you first hook it up it will probably have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
    In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
    The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
    You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse.  http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
    Or if you want to use the MacBook’s keyboard and trackpad to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.

  • HT1320 Ipod 4th gen was accidentally disconnected from laptop during update process. Now permanent screen pic is of power cord w/ an arrow pointing up to itunes. Holding the ctr & power buttons together has no effect for reset.

    Ipod touch 4th gen was accidentally disconnected from laptop during update process. Now permanent screen pic is of the power cord w/ an arrow pointing up to itunes symbol. Holding the ctr & power buttons together for 6-10 sec causes apple pic to briefly appear and power cord/itunes pic reappears. Powering off and on has same effect. Attempting to reset.

    It sounds like the iPod touch is in Recovery Mode, Try to restore it from iTunes again.

  • Unable to switch back to laptop screen with xrandr from VGA

    HI,
    I'm using i3 window manager and have an external display plugged in sometimes. I use the following short script to turn off the laptop display and turn on the vga monitor
    xrandr --output VGA1 --auto
    xrandr --output LVDS1 --off
    xrandr --output VGA1 --auto
    feh --bg-fill /home/james/wallpaper.jpg
    synergyc 192.168.0.4
    However I cant get back to the laptop screen turning the VGA off doing it the other way round.
    xrandr --output LVDS1 --auto
    sleep 2
    xrandr --output VGA1 --off
    sleep 2
    xrandr --output LVDS1 --auto
    sleep 2
    feh --bg-fill /home/james/wallpaper.jpg
    pkill synergyc
    I've tried using --mode 1366x768 but that doesnt work. The only thing I can do is close the laptop lid and then resume from suspend and the screen comes back on.
    Anyone know what I can do to get my laptop screen back on?
    Thanks.

    Try the whole thing together
    xrandr --output LVDS1 --auto --output VGA1 --auto --right-of/left-of/above/below LVDS1.
    If you have it plugged in, it runs both, if you unplug it only brings the one back on.

    I do backup with iCloud.  I can't wait until the new iMac is available so that I can once again have my files in more than 1 location without needing to rely solely on the cloud. 
    I also rely on iTunes and my MacBook and Time Machine as well as backing up to iCloud. I know many users know have gone totally PC free, but I chose to use iCloud merely as my third backup.
    I assume that the restore would result in my ability to open Pages and Numbers and fix the problem with deleting apps, but this would also mean that if my Numbers documents still exist solely within the app and are just not on iCloud for some reason that they would be gone forever.  Is that right?
    In a word, yes. In a little more detail.... When you restore from an iCloud backup, you must erase the device and start all over again. There is no other way to access the backup in iCloud without erasing the device. Consequently, you are starting all over again. Therefore, it would also be my assumption that Pages and Numbers will work again and that the deleting apps issues would be fixed as well.
    If the documents are not in the backup, and you do not have a backup elsewhere, the documents could be gone forever.

  • How do I move Firefox from my laptop screen to my desktop monitor

    My IMac laptop was disconnected from my desktop monitor during a session using Firefox. When the laptop was later reconnected to the desktop monitor, the Firefox window continued to appear on laptop screen and not the desktop monitor screen even though the Firefox icon and toolbar shows on the desktop screen. This problem only affects Firefox and not Safari.

    Install Zune on the laptop if it's a Windows PC or use the Windows Phone Connector on Mac. For Zune see the support page for more information. You can also copy your pictures to SkyDrive and from there access them on  the Phone.

    Connect the phone to iTunes on your computer, right click on it in the device list and choose "backup". This will save your data and settings.
    Purchases can be transferred by choosing "transfer purchases".
    After that import photos or videos to your computer.
    You can use the backup again to restore the phone after it has been serviced.

  • How can I stop Firefox from 'talking' every time I click a new item on my laptop screen?

    Without my doing anything, all of a sudden my Firefox started talking every time I click something on my laptop screen. Example: I clicked the link that took me to this page. Firefox said "new window... Firefox menu ... Ask a New Question ..." I don't need this, it interferes with all that I do that requires my speaker turned on. How can I stop this?

    You can also manage all permissions on the about:permissions page via the location bar.<br />
    Use "All Sites" to set the defaults.
    You can open about:xxxx pages via the location bar like you open a website.<br />
    Firefox uses the about: protocol to access internal Firefox (setting) pages.

  • HELP!! PSE7 Downloader doesn't fit laptop screen

    I've recently upgraded from pse4 to pse7 and have just found the 'advanced settings' button on the downloader. However, the window this opens is too big for my laptop screen and I can't access the 'get photos' button. I can't get the window to move like a windows window. Can anyone help?
    Thanks

    Interesting, the Advanced Dialog window is 812 pixels high, larger than the 768 typical of a laptop (and the minimum required by Adobe for PSE).   And PSE doesn’t let you make the window any smaller.
    Here’s how to move the window around if the title bar isn’t visible: Click anywhere within the window. Then hold down Alt and Space at the same time.  Release Alt-Space and type “m”. Now you can use the up/down/left/right arrow keys to move the window around.  Left-click with the mouse when you have the window where you want it.
    You can try this on other top-level windows first to see how it works.
