Mac Pro LCD screen won't turn on

The LCD screen on my Macbook Pro doesn't seem to be turning on. I have restarted the laptop couple of times, battery seems to be alright and the keyboard lights up and I get the bootup audio, but no image on the screen

Hi chhophyel, and a warm welcome to the forums!
It may be the Video card, but try a Safe Boot, (holding Shift key down at bootup), does a Gray Radian show?

  • Mac Pro (Mid 2010) Won't turn on sometimes?

    Hi sometimes when i try to power up my mac pro it won't turn on? like today i pressed the power button twice then it never starts up or plays the mac music it just sounds like its gonna start but never starts. after like 2 or 3 trys it will start any suggestions on what to do ? or any upgrades? its all stock right now.

    No it does not blink. and i have tried reseting PRAM and SMC. Let me rephrase the problem, When i press the power button on my mac pro it will give power to my keyboard and mouse and audio interface, but the computer led above the power button doesnt light up and there is nothing going on in the actual computer screens won't turn on anything even if i let it run for 25 minutes it won't start up. so i have to force shutdown by holding down the power button for five or so seconds. Then the second time i hit the power button it usually works. and starts up correctly.
    this happens every time. it usually takes me powering it up once and force shutting it down then powering it up again to work sometimes i get it on my third try? i have reset my smc by
    Shut down and unplug the Mac.
    Keep the Mac unplugged for at least fifteen seconds.
    Plug the Mac back in and do not turn it back on for at least five seconds.
    Press the power button to turn the Mac back on.
    and i have reseted my pram by holding down command option p and r til i hear the mac music play again.
    my computer is working just fine minus i have to start it up twice for me to get to actually use my computer.

  • Eos-m LCD screen won't turn on

    The camera works, allows me to take photos, however the lcd won't turn On just stays black. So i have no view of what I'm taking photos off. The touch sensor works as it makes the usual noises and allows me to take photos touching. Any idea why the screen is getting no image at all, not even menu? Thanks!

    Will any buttons activate the rear LCD screen (for any purpose)?  e.g. can you press either the "Menu" button or the "Info" button and get a display?
    On EOS DSLRs the "Info" button cycles through several choices to display on the rear LCD and one of the choices is to just have it off -- but that's because regular DSLRs have a viewfinder.  The button simply keeps looping through the choices.
    But on the EOS-M there is no viewfinder and I didn't think there was an option to disable the LCD when the camera is on.

  • Mac Pro - Grey Screen; won't start

    I am having problems with my Mac Pro.  Had to replace the graphics card last week as both cinema displays packed up (coloured lines all over both monitors) and the computer has been fine for the past day or so.
    During some work tonight, the computer froze and completely stopped working - had to power down by holding down the power button.  On restarting, the apple logo comes up but after a few seconds this disappears and, at the point where I expect the desktop to load, nothing happens.  I have left the compute for 10/15 minutes to see if it starts but absolutely nothing happens.
    Again, I am forced to power down by holding down the power button and the machine will not start at alll now.
    Have reset PRAM but this has made no difference.
    Grateful for all help and suggestions.

    Mac OS X: Gray screen appears during startup

  • Mac Pro froze now won't turn on

    I plugged a usb cord (prom an Epson printer) into my 2008 Mac Pro, next thing I know everything is frozen. Turn off the Mac Pro now I can't get it to turn back on.  I've unplugged it from electricity and retried, I've taken off the two exterior hard drives that were connected via firewire and the usb printer, nothing seems to be bringing this computer back to life.  Any ideas or suggestions?  The computer was working completely fine a half an hour ago.
    thanks  jeff

    Ok  got it back on after waiting 45 minutes (reading every post on the internet I could find on the subject) I had reseated each module of ram (testing one pair at a time), each hard drive.
    As for the Apple Hardware test I can't find it.  I purchased the family license (5 machines) of Snow Leopard (from Apple) and only received one DVD - I have a special CD case for these DVDs and I know I didn't lose the other.  I've tried to restart it both with the instal DVD and without the DVD holding the D key and neither way brings up the Apple Hardware test or any language page.
    I've rebooted holding the C key and run the repair permissions on the boot drive from the install CD. I've zapped the Pram  the front light is on now full not blinking nor has it ever blinked during this ordeal.
    Any suggestions on my next course of action as I know the problem has not been fixed and will come back when I need to work?
    Thanks,  jeff

  • Macbook Pro A1226 screen won't turn on

    I have a MacBook Pro A1226.  The computer has been working fine, however tonight when I turned it on it made the chime booted up, and I could hear my applications running (Skype and Trillian were both making sounds), Caps Lock light goes on and off, keyboard lit up, however the screen seems to be completely dead.  No backlight, and no activity.  I hooked in an external monitor, and this made no difference.
    Any ideas?

    Well, went to the local apple store...the outcome wasn't good.  The 'genious' had a 6 hour wait...I couldn't stand around there that long waiting to just talk to someone for a few mins, so that was a no go.  The sales person looked at it and said that given the age, they don't carry parts for it anymore anyway I'm not sure if this is a complete lie or not since there wouldn't have been any point for them trying to talk to a 'genious' if that wasn't the case.
    Took it to another store and they were basically saying the same thing that a new logic board would cost $1200...more than what a new one is worth.
    I see numerous 'repaired' boards on ebay...does anyone have any expereince with these...how long can I expect it to work for etc.  I'd like to get another year or two out of this machine if I can.
    I'm hesitant on buying a new Mac at this point.  They are literally 3 times the price of a comparibly powered PC (with the same parts in it) and the new ones are far too thin for my liking and no dvd drive (which I do use)....if this one has issues, I'd imagine a new one is going to have simular issues down the road...they're just too damned thin for it to have any reasonable level of cooling in it.
    I guess I'm out of luck.
    Anyone know what the computer would be worth for parts...

  • My macbook screen won't turn on and it keeps beeping at me...help!

    I tryed turning on my macbook pro 13'' and the screen won't turn on and it keeps beeping at me and flashing the white light on the front of the computer at the same time.  any suggestions?

    Beeping sounds usually indicate a RAM or logicboard problem.
    If you have third party RAM recently installed, put the factory RAM back in.
    Use the free MacTracker to find out your correct RAM spec and return the defective RAM for a exchange or buy top tier RAM from Crucial.com or OtherWorld Computing.
    If you didn't mess with the RAM, take the machine to Apple for a free eval.
    You might want to read this if the repair bill is not worth it.

  • 2008 MAC PRO - ORANGE Screen of Death, well death of your video card.

    2008 MAC PRO - ORANGE Screen of Death, well death of your video card.
    My wife's MAC PRO had this occur yesterday, here is how I solved the problem as the system was out of warrantee. System had the NVIDIA GeForce 8800 GT for the MAC.
    Symptom: System starts boot as normal, see the grey apple screen, just as the desktop screen is to start, the screen turn completely orange. Attempted several reboots, holding down the diagnostic keys, re-installed the video card after cleaning, all these actions resulted with the orange screen.
    Solution: Go to the Apple store and buy the NVIDIA GeForce GT 120 Graphics Upgrade Kit for Mac Pro - around $149 at time of posting. The card will work in a 2008 MAC PRO as long as you have upgraded to Requires Mac OS X v10.5.6 or later. Card has DVI and MINI Display port so I also purchased the Mini DisplayPort to DVI Adapter (you can find these online for less then the Apple adapters) to support my wife's second monitor.
    Replace the NVIDIA GeForce 8800 GT with the NVIDIA GeForce GT 120 and system started right up with no issues.
    Hope this helps.

    Sort of falls into the "common sense" though the GT120 cost and performance, I would have recommended the ATI 5770 for $100 more is all.
    What is annoying is Apple doesn't offer a 10.6.5+ DVD to boot from or a way to slipstream the ATI support drivers. Some Mac Pro (2009) can boot with 10.6.3 DVD with the ATI 5770 but in general you need 10.6.4-1/2 (the Mid-2010 build number).

  • [Help]iPhone 5s screen won't turn on / won't play sounds

    Hello, my name is Bryan.
    I've got a problem with my iPhone 5s. I opened my iPhone to fix an issue with the home button (Watched a guide on youtube on how to achieve this), and I connected everything as it is supposed to go, my home button is working but now my screen won't turn on or the phone won't play any sounds. I know the phone it's on because I can connect it to the computer and the computer recognizes it. Also, I tried calling it, and it rings on the phone I am calling from, but my iPhone simply won't play any sounds...
    I am also sure the phone is not in DFU mode.
    Any help?
    Thanks in advance,
    - Bryan

    It won't even vibrate or do anything, but it's on.

  • Macbook Pro Retina 15" won't turn on.

    Macbook Pro Retina 15" won't turn on. The charger light is orange. I tried all tips that Apple provides on the official site -  http://support.apple.com/en-us/HT204267. Any ideas?

    If you purchased it from Apple directly, they have a 14 exchange or refund policy.  Keep that in mind when you go to the store.
    Ciao.

  • Mac mini 2,1 won't turn on

    Hi Guys,
    i have a really big problem with my mac mini.
    It won't turn on.
    I don't think it can be the power brick as I can get the mini to start up by holding down the power button whilst plugging it in.
    This is the incorrect SMC reset procedure and I get fans runnning top speed and no LED light.
    When i startet with this method, everything works.
    Ah ups i forgot:
    I have all resets done!
    NVRAM
    SMC (and by reset switch)
    New Battery
    Bought a new power adapter
    etc

    Hi,
    Witch power adapter you bought ?
    I have the same problem i bought a 85w pwer adapter and my Mac mini don't work anymore and i replace it buy a 110w and it works fine .
    Probably you are in the same case.

    The Mac Pro - the desktop computer - does not support Airdrop, if that's what you mean.

    After I dropped my Iphone 4s my back glass broke and now the screen won't turn on neither respond to touch but i can hear incoming calls and notifications. I tried pluggin to computer/other power sources and also tried pushing the home and power button together for about 20 seconds

    It's broken due to neglect, namely being dropped.  Replace it.
