HELP!!! Black screen, nothing helps

PLease help. My ibook g4 started having black screen: i can hear the chime but the screen remains black. Sometimes it does turn on, but almost immediately the message asking to restart appears. I have tried all the regular fixes: setting changing, os re-installed etc. Support told me that it is probably hardware issue. What do I do now? Do I go to the store and pay them to fix it? Does anyone know how much? Please help.

Andosia, did you call Apple?  What did they say?
I've had a dead iBook G4 since last November-ish.  There are a few suggested fixes, one of which is taking your iBook apart and putting a shim in the case to put pressure on the chip.
A couple of months ago I put a wood clamp on the left palm rest of my iBook and it booted up without a problem.  I had it running (with the clamp attached) for nearly six hours without a single problem, and during that time I was able to get all my personal information off of it.
Now, in the past I was quite adamant about not taking apart my iBook when it's the responsibility of Apple to fix this issue, but today I finally broke down and took it apart.  I figured I may as well, it was just a $1100 paperweight as it was.  But as I type this on my wife's MacBook (which we bought to replace her iBook), I have her previously dead iBook up and running with a shim placed on top of the graphics chip.  I'm currently loading Panther from the Restore Disk because I wanted to give it a clean re-install, but it hasn't given me a single problem yet.
I still very much feel it's Apple's responsibility to fix this problem, but I'm not holding my breath, and at least now I have a working (for how long?) iBook.

    Yes, that is your only option.Yes.  You have to restore.
    Try the following if you have difficulty restoring.
    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • I have some error with my iphone 5 in black screen nothing shown

    i have some error with my iphone 5 in black screen nothing shown nothing do no restart and when i have restore my iphone it say error 4014????????????

    is this the original iPhone 5, or 5s? If it's the 5s do you have Apple Care still? If so calling Apple iPhone support is where to start, hopefully they can help, if not, setting up an appointment at the Genius Bar at an apple retail store is a good option too, Call the store first though and ask what your options are in terms of warranty and service. If you are having problems with the regular iPhone 5, still call Apple Care or an Apple store and see what they can do.
    good luck!

  • TS1538 iPad not turning on. Vertical colored lines followed by a black screen. Help!

    My iPad is a little less than a year old. While playing a game on my iPad, multicolored vertical lines appeared across left side of iPad followed by a black screen. After a few seconds the screen flicked back on....then a few more vertical colored lines and completely black screen again.  Initially when pushing home button I heard Siri but after attempting several times to restart iPad, soon I no longer heard Siri and screen was just completely black and iPad seems to be dead. Battery was at 60%. I attempted to plug into wall and charge anyway, but that did nothing. I also attempted to plug into iTunes but iPad screen remains black and isn't recognized by computer or iTunes. (No apple logo shows up...nothing) Resetting by holding home button and reset switch for 10 seconds isn't working...I tried over and over holding both buttons for way over 10 seconds. Please help....is it dead? Anything else I can try on my own?

    I have the same issue on my iMac 27" i7 late 2009 with ATI Radeon HD 4850.
    Booting in safe mode is the only way to use it but the system can't do much and it's really slow.
    From my findings it's for sure a GPU or VRAM issue so I've just bought a spare GPU board to replace the fault one.
    Reballing could also solve this issue but usually you need also a new ATI GPU as well.
    I'm not sure about nVidia GPU but it seems that you can replace it with a more powerful ATI Radeon HD 6970M card (if you use games to take advantage of it).
    Your post is one year old and probably you already solved the issue so would be nice if you could share your solution for it.

  • HP Pavilion a6000 desktop with Vista black screen - need help please!

    I have an HP Pavilion a6000 desktop with Vista.  Yesterday it was working fine and today we have the black screen that reads: 
    Award BootBlock BIOS v1.0
    Copyright (c) 2000, Award Software, Inc.
    BIOS ROM checksum error
    Detecting IDE ATAPI device...
    Found CDROM, try to boot from it...Fail
    Detecting IDE ATAPI device...
    Detecting IDE ATAPI device...
    Detecting floppy drive A media...
    Drive A error.  System halt
    I am not a techie, but looked at online forums and have tried f10 at startup with no change to the screen other than it stops after the first four lines and does not try the floppy drive.  I also pulled out the round battery, waited and then reintstalled.  Same problem.  
    Also, computer emits a single, repeating beep after startup.
    HELP!

    I saw your post and wanted to comment. I'm not an expert on these types of situations but did some digging around and found the following at Tips4PC.com.... read below
    "There are two types of computer black screens that can appear in Windows. One where the computer will not boot up but you have a beep sequence sounding to let you know what the problem could be, and the other has nothing at all. No beeps, no cursor, no logo screen, and no choice to boot to safe mode or access the bios.
    If your computer will not boot up and you get a beep sequence, I am not saying it is good news, however it is a step in the right direction towards solving this problem. This is a message from your computer that can be understood by looking up your bios (the brand) beep code. For example you may have an Award Bios, Ami Bios, Phoenix BIOS, Compaq, Dell, or Acer Bios. This list goes on and on.  You can search for Bios beep codes in Google. Here is an example of results in Google search"
    Link
    Also  I went into the Troubleshooting Guide for the A6000  and found the following information.  You need to use F11 for recovery. See below
    Starting System Recovery from system startup
    1
    Turn off the computer. If necessary, press and hold the On button until the computer
    turns off.
    2
    Remove the HP Personal Media Drive if your computer includes one. Disconnect all
    peripheral devices from the computer except the monitor, the keyboard, and the
    mouse.
    3
    Press the On button to turn on the computer.
    4
    During the startup, do the following to enter the Recovery Manager program:
    When the blue screen with the HP Invent logo appears, press the F11 key on the
    keyboard. (You have only a few seconds to press the F11 key before the normal
    startup process continues.)
    5
    The computer starts the Recovery Manager program; wait for the onscreen instructions
    to display, and then follow those instructions.
    6
    Complete the computer startup, finish the registration process, and wait until you see
    the desktop. Then, turn off the computer, reconnect all peripheral devices, and turn on
    the computer.

  • Please help - black screen blinking cursor 24" imac and XP home sp2

    Brand new 24" imac purchased yesterday from the apple store with a 4 gig ram upgrade (i.e. all the newest stuff/versions). All updates installed & current.
    Brand new (clean & scratchless) copy of Windows XP Home with SP2.
    I ran the bootcamp assistant and made a 20 gig windows parition (so its under the 32 gig limit of fat32).
    Following the installation procedure the windows disk is inserted, the machine reboots and then it just sits there with a black screen and a blinking cursor. The CD drive stops spinning and no progress from that point forward.
    I then read on here some had better lucky with a "copy" of the original windows disk so I duplicated it in this Mac (i.e. burned with its own drive) but exactly the same problem with the burned copy (which also opens fine from within OSX).
    I'm at a loss... where to go from here? We decided to try apple because they assured us we could run our "windows only aps" on the bootcamp side of the hardware but bootcamp isn't working!
    Please advise...
    If any of this helps:
    OS X Version 10.5.2
    2.8 Ghz Intel Core 2 Duo
    4 GB 667 Mhz DDR2 SDRAM
    Model name: iMac

    Welcome to the Apple forums:
    Be sure your XP disk had SP2 embedded into XP, and not a separate file or patch.
    Also be sure your disk is not an ISO image but a real disk, with files on it. You can look at them using your Mac. Insert the CD or DVD and doubleclick the disk icon.
    You should see most or all of the following files and folders:
    (HOMEWITHSP2)
    AUTORUN.INF
    DOCS
    DOTNETFX
    I386
    README.HTM
    SETUP.EXE
    SETUPXP.HTM
    SUPPORT
    VALUEADD
    WIN51
    WIN51IC
    WIN51IC.SP2
    When you copied the disk, did you make sure your copy was Windows readable? Mac has several formats, one of which is Mac-only for data CDs. You need to select the universal mode, Mac and Windows for the data image and when burning the image.
    Also be sure you selected to close or finalize the CD after burning or it cannot be read by Windows.

  • Please help. black screen when copying back to tape

    I would be very grateful of any help. I am trying to copy a movie back to tape however when i do so it results in the recording on the tape being completly black. it has gone through the process but just left a black screen.
    very desperate.
    Thanks

    ... and it did work before...? not all European camcorders allow a DV-IN...
    cable checked?
    finally: iM handle both video standards, even allows to import PAL footage into a NTSC project.. but cameras are 'hardwired' to one standard.. make sure, your project has same standard as camera.. (besides: Apple lingo is a little 'cryptical': '25 frames per second' = PAL, '30fps' = NTSC)
    it could have happen, that you incidently created a NTSC project with your PAL footage. and now, it is impossible to playout THAT into/onto (english??) tape ...

  • My iPhone 3gs is stuck on a dim black screen. Help!

    My iPhone 3gs is stuck on a dim black screen that I can't get out of. I tried doing a hard reset and even restoring to factory setting to fix it. When I press the on/off button it switches from a solid black screen to a dim lit black screen. The fuctions seem to be working. The vibration works when I flip the switch on and off. The voice comand comes up when I hold down the home button. It even plays the iPod when I use the voice comand. When the dim lit black screen is up, the touch screen is non responsive. I just need a way to fix this phone. I know their must be a way. Please help!

  • Pavilion g6t wont boot after bios update now just black screen please help!

     I downloaded an update for the bios for my pavilion g6t-1d00 laptop running windows 7 64 bit. It started acting kind of funny but I didnt think anything of it til I tried to boot it up the next day and all I got was a black screen and a orange led light on the f12 button for the internet and the caps lock button after blinking afew times started the dredded two times every couple of seconds. I tried the windows key+B key power key, no luck. I cant access anything because I have no monitor and I'm at my wits end. I refuse to wipe my hard drive and start over even if I could! I cant access hp tools or manager or anything, please someone has to have a solution!

    @Fuschia4me,
    1.       You will have to use another computer
    2.       Access the HP.com site with the BIOS updates available here is the link
    3.       You want to select the F.36 BIOS version
    4.       When you click on the update then click download and it will ask you to save or run, you want to save to a flash drive
    5.        Once done insert the flash drive into your laptop
    6.       Turn the computer on and press the windows and B key like before
    If the process doesn’t work the first time I would try at least 2 more times.
    Please respond back at your earliest convenience.
    Thanks

  • [4S] Replaced what I thought was faulty rear camera, still getting black screen! Help please?

    I will try to describe the problem as well as I can; I've seen quite a few posts about this problem already but I am yet to find anything that really helps.
    Basically, I thought my rear camera had a hardware problem as when I opened the camera app all I would get was a black screen. Despite this I was still able to use the front camera without a problem. Thinking it was the camera I ordered a replacement which I have since installed and I am still getting the same issues as with the old camera.
    I'm comepletely stumped, I've looked at many forum posts etc. about this and have yet to see anything that is helpful.
    Is this a software issue?

    Nobody here would know. You took it unto yourself to repair a non-user servicable item instead of going to an Apple store or authorized servce provider when you had the original problem.  Your best bet now is to go and do a Google search or take it to a third party (unauthorized) service shop. Apple will never touch that phone.

  • Please Help: Black screen on Start up.

    We lost our power due to a storm yesterday. My week old intel iMac was asleep when the power was cut and when I re-booted, all I got was the start up sound and then a black screen.
    The light in the mouse is visible and when the spacebar is pressed I hear the error sound.
    I have re-set the pram several times as well as left it un-plugged for and an hour. No change.
    Any ideas?

    Insert your installation disk, restart your Mac while holding the 'C' key down. It will take a little longer, but once booted up, choose File>Utilities>Disk Utility and Repair the Disk. Then restart as normal and see if that helps. You may need something more robust from a 3rd party, like DiskWarrior (which I think should be owned by all Mac users personally), to perform a proper repair. But anyway, try this and post back.
