Macbook Pro to Sony Bravia NOT WORKING...PLEASE HELP

Hi,
I am trying to connect my *macbook pro* to my *Sony Bravia TV*.
So far I have the macbook pro - mini display to VGA converter - VGA cable - PC VGA socket in the back of the TV.
When selected on PC mode, the mac display turns blue for about 3 seconds then returns to its original state whilst the TV has a black screen with 'NO SYNC' in the top left hand corner.
The VGA cable is brand new and the mini display converter works as i used it on an old TFT monitor which died...hence why i am trying to connect it to my TV : )
Any tips/solutions would be amazing!
Thanks
Jon

Had the same problem with my 40" Sony Bravia LCD. I tried for ages to connect MiniDisplay to VGA. The TV would never recognise an input signal and the MacBook wouldn't acknowledge any change and I eventually gave up.
Recently, I checked the Bravia manual and the highest possible resolution for my model was 1360x768. So I set the MacBook display to one of the nearest: 1280x800. I connected the cord and then closed the MacBook lid for a few seconds and reopened it. The signal kicked in! The mac then gave me the option to reset the VGA to optimal display - I used the table at the back of the Bravia manual to reset it to the highest display compatible with the available mac options (1280x768, 60Hz). Now it works perfectly, but still only when first set to 1280x800, nothing less or more!

  • My MacBook Pro's sound is not working! HELP!

    This problem heppened when I was using my headphones.
    When I try to change the volume on my computer, it gives me a sign that it is locked.
    I have tried restarting, plugging and unplugging headphones, and fiddling in the port with a tooth pick.
    Thank you

    Do the internal speakers  work?
    Go step by step by step and test.
    1. System Preference > Sound > Output > Internal Speakers
        Highlight  Internal Speakers / Headphones
        Make sure that Mute is not enabled.
    2. Hold the option key down, click the sound icon in the menu bar and select internal speakers or headphone.
    3. Any red light visible in the headphone port
        Even if there is no red light visible, plug in the headphone in and out 6. or 7 times.
    4. Launch iTunes and play a song. Try to move the volume slider in the mini player.
    5. Close all windows and quit all applications.
         Launch Finder. Select Macintosh HD in the Finder sidebar.
         Macintosh HD > Library > Preferences
         Open "Audio" folder.
         Right click these two files and select "Move to Trash".
         com.apple.audio.DevicesSettings.plist
         com.apple.audio.SystemSettings.plist
         Close the window. Restart the computer.
    6.  Reinstall OS X  10.9 Mavericks

    If this does not help, you may have to take the computer to the Apple store to have it checked out.

    If you are running Lion or Mountain Lion, the drivers are downloaded from within Bootcamp Assistant. If you are running Snow Leopard the drivers are on your Snow Leopard install disk.

  • Hi all, I'm trying to connect my macbook pro to Sony Bravia tv using Kanex Mini DisplayPort to HDMI Cable with Audio Support , when connected to the HDMI on tv I get a picture of the mac screen saver ( the starburst ) no video/audio,thanks, Derek

    Dave I'm glad to say that it works perfectly but I'm embarrassed to say that my 12 year old nephew hooked it up in about 10 minutes.
    If you have the Kanex Mini DisplayPort cable it will work, what confused me was changing the display settings in System Preferences,
    and dragging the mac screen from the mac onto the tv. Sorry I cant be more helpful but you have the right cable now you need a 12 year old nephew.
    Good luck Derek

  • My MacBook Pro internal speakers are not working, what happened?

    My MacBook Pro internal speakers are not working, what happened? If I plug in earbuds or external speakers, there is sound. In sound preferences, internal speakers are not a choice. Why doesn't my internal speakers work?

    Hopefully one of these steps should solve the problem.
    1. 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.
    2. Reset PRAM.  http://support.apple.com/kb/PH4405
    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.
    Best.

    I have 4s iPhone , I download the iOS 7. Now the front receiver microphone is not working , please help me that how to fix the problem.

    I live in South Africa, and I had the same problem with my iPhone 4.
    After weeks of frustration and swearing, I was in the process of restoring my phone to a previous iOS. To do that you need to turn the "Find my iPhone" option off, since i turned it off, my problem was solved. No need to repair anything or revert back to old iOS.

    I would imagine your iPhone was hacked to make it work on your local carrier.
    Updating the iOs to 5.xx will lock it back to the original carrier .The carrier holding the lock are the only
    entity able to authorise the unlock .You will have to contact them and see if they unlock and the terms the apply
