Laptops :: IBook G4 Black Screen Except For When In Target Mode
Sep 11, 2010
1st time posting to this forum. My iBook G4's (1.2 Ghz) screen flashes grey/white for a brief second upon startup and then remains black. No ghosting at all... simply black screen though computer is running fine. Later, I decided to connect it to my desktop Mac and restart it in Target mode, and was surprised to see the standard blue screen with moving Firewire logo screensaver on my iBook's screen - no different than anytime before when I've booted in Target Mode.
I ran Diskwarrior on my iBook's HD from my Mac desktop and all was clean so not a HD problem. Btw, I used SuperDuper to copy my iBook's HD to Disk Image for backup.
With some semi-calculated guessing on my part, I had come to the conclusion - prior to seeing the Target Mode screensaver on my laptop's screen - that the LCD screen had gone bad. As a result of what may have been flawed reasoning on my part, I purchased a used replacement screen off eBay from a reputable seller. I will be getting that replacement screen in a few days (including working inverter board).
My question here is can the LCD screen actually be bad and need replacing IF the Target Mode screensaver works beautifully on it? And the follow-up question is if it's not a bad LCD screen, what might the more likely problem be? It doesn't seem like it would be a backlight problem because moving yellow/orange Firewire logo of the screensaver looks fine.
A couple of things probably worth noting here:
Earlier before first experiencing my black screen issue, the power cord was accidentally jerked by a passing foot when laptop was on floor. It was enough of a jerking motion to move the laptop's position on the carpet but I didn't think it was that bad at the time... now wondering if something may have been pulled loose inside.
As those familiar with the iBook will know, the power connector light is orange when computer is turned off and it's also orange when laptop is in Target Mode (with the screen seeming to work correctly). However, when not in Target Mode and turned on with screen black, the power connector light is green as it normally would be. Is it possible the screen is powered via Firewire port when in Target Mode and therefore bypassing some screen power situation via the power connector? Obviously the power connector must be working if i'm able to power up the iBook without the battery installed.
Now for the other bit of info which seems important to me and I'm embarrassed to even admit to here.. Just prior to experiencing my black screen problem, i was plugging my power connector into an electrical outlet near where I was going to use my iBook... In the past, I have always done that PRIOR to plugging the power cord into my iBook. Regrettably, that time I already had the power connector plugged into my iBook. While attempting to plug the connector into the electrical outlet, the prongs did not easily slide into the outlet and I heard some popping sounds which didn't seem too bad at the time. But it was immediately after that when my iBook's screen failed to start up.
Thanking anyone in advance who may be able to offer up some expertise regarding my situation. Also I should say that I am running OS 10.5.8 on my iBook. I realize the easiest thing for me to do to get this matter resolved would be to simply take the unit into a local service center for repair... but the value of the iBook at this point wouldn't be worth spending a large sum of money for repairs I likely can do on my on. Over the years, I've learned how to follow direction pretty well when it comes to replacing defective items inside my desktop computers, so I'm not terrified of doing same with my iBook.
My screen went black after sleep and now I can't do anything anymore. I restarted a few times, tried to start from backup (USB) and also to mount in target mode via another computer, but nothing is working. I first thought the graphics card had gone, but that doesn't seem to be the case now as it's not showing via firewire. The computer is on as I can hear the drive spinning. it woul
Nothing particular happened beforehand. It worked fine, although a bit sluggish earlier. I do maintenance quite regularly and it has been fine, except that the battery needs replacing.
My ibook G4 turned itself off and when I tried to power it up the fan turns vigorously while the screen stays black. Thats it.
Prior to this I was doing some pretty heavy music importing and during that time the fan was going nuts (I then stopped importing)...also while it was charging it the past few nights the light on the connector would go out and it stopped charging while it was still plugged in. This was the first time it happened and it happened 2-3 times.
Like for most people my entire life is on that computer along with a very important document that I need to access ASAP. What could be the issue...not the logic board!
I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.
I'm trying to zero the data on an iBook hard drive before selling it. When I connect it to my Powermac via firewire in Target Disk Mode, it shuts down completely about 30 minutes into the proceedure (and yes, the power adapter is connected).
I have a MacBook Pro (13'', Early 2011) & iMac (21.5", Mid 2011) using a Thunderbolt Cable to Target Display. Everything was working find and I could Command F2 to Target Display as expected.However, about a week about this stopped working. Now when I try to Target Display the iMac goes to a Black screen (like it's switching to Target Display) and the MacBook Pro does nothing. The iMac will be at the Black screen until I Command F2 again (or disconnect the Thunderbolt Cable), then the iMac goes back to the normal display. I have tried another Thunderbolt cable with no luck. I have perform all software updates on both machines (now both running 10.7.3) and fixed Disk Permissions. I have also found that restarting my MacBook Pro allows this to function as excepected (Command F2, Blue Flashing Screen, Target Display on the iMac). However, this is not an ideal situation since having to restart my computer is time consuming.
I'm traveling at the moment with my MBP 17". Arrived at my friends place who has a base iMac 21.5". Since I prefer to use the slightly larger screen to work off (even though my 17 MBP has more pixel density). So startup the iMac via TDM on my 17 MBP and to my surprise it works! - as my MBP only has leopard 10.5.8. I would have thought these iMacs would not run unless you have SL 10.6 loaded. It worked the 1st time, but crashed (grey vertical shade of death) twice after. On the 4th time it worked again. So that was weird (the inconsistency). Maybe 10.5.8 is NOT meant to be compatible with the new iMac's?
My MacBook Pro won't turn on. When I turn it on, I can hear the motor whirring, but the screen stays black. I've tried leaving it off for an extended period, I've tried unplugging the charger, leaving it to charge for 24+ hours, taking the battery out, checked that the screen brightness wasn't accidentally turned down, everything!! It started about 2 weeks ago, since then it's turned on a couple of times, but when I stop using it and it goes into sleep mode, or I turn it off, it won't come back on again. Not sure what's wrong with it, but there's some urgent files I need on that computer! I also have an iMac, which I was hoping to transfer the files to, so I can send the laptop to be looked at. So, I have 2 questions...
1. What is most likely wrong with the laptop, and is it something I can fix so it will turn on again? 2. Is there a way to transfer the files from the laptop to an external HDD or my iMac even though the laptop has a black screen.
I'm trying to fix the blank screen but I don't want to use any heat. I found this method. This is the only one I found that didn't use a blow torch or such. [URL] Do any of you know where I can get a heatsink like that or if just the fins are available anywhere? I'm not sure what to search for when I do it online and I tried different variations but all the heatsinks I find have fans. I don't want to spend more than I have to since I don't need the fan. I also don't really want to buy online unless I can't find it in a retailer.
I have an iBook G4 (14-inch screen, 1.42 Ghz.) and it has a cracked screen. I also have a PowerBook G3 PDQ (14-inch screen, 233Mhz.) with a good screen. Question: Can you swap the screens even if they were made 7ish years apart?
I have an old iBook graphite SE (466MHz G3 320RAM), which I haven't used for quite a while. I have loaded 10.3.9 on to it and it's working fine.
The only problem I have is that the screen wont display the the full width of a page when I am using Safari (1.3.1), I have to scroll from left to right to see everything, (screen set to 800X600). Other applications seem to be ok. I realise that it's all pretty old stuff but can it be fixed?
I have a 15" mbp with 10.6 Intel core duo, 4gb ram with a boot camp and ubuntu partition through parallels. The other day I was installing xcode from apple's website, which failed 3 times after downloading saying the package couldn't be expanded. I left my computer for a while and came back where i then had to log in again. it rejected my password numerous time (i'm positive it was correct). when i restarted my computer i got a kernal panic screen when the apple logo came up. it told me to restart the computer which i did. didn't work. i restarted with the osx cd to use the disk utility. when it checked the drive it found a bunch of errors, which i then tried to correct. it went for a couple minutes then told me they couldn't be fixed and i should try to back up my data and reinstall osx. i don't know how to back up my hard drive when i can't log into my account. i've tried to boot in target disk mode and copy some files that way, but the only disk the other computer sees is my windows partition- no mac partition.
i've also tried these, none of these have worked: restarting in safe mode resetting the ram and pram booting with different sticks of ram all result in a kernal panic.
my windows partition still works fine though (as much as i hate to say it) the only things I really care about on my computer are my files from school and my itunes library. is there any way i can get these files off my computer?
have an iBook 12" the screen and the screen is very grainy, disintergrated image and text?Loads up perfectly and functions are all good , just hard to read the vague image.Any clues?Supposedly it has had the motherboard replaced by the dealer who said it is the screen. But not sure if i can believe this.
So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.
When my MacBook Pro 13" i5 goes into screen saver mode, which is black, it won't return to normal mode. Tried all keys, trac pad, closing the lip and re-opening it, and it won't respond. The only thing that works is holding down power button for hard shutdown, then restarting it. It has happened 8 times in the last 2 weeks.
My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!
I just installed SwitchRsX which is an app which allows you to create a custom resolution for your display (so instead of 1680x1050, you could do 1680x960).
As a last resort, if you can't even start SwitchResX itself, you'll have to delete the monitor profile that was modified when you created a new custom resolution. This file is located in /System/Library/Displays/Overrides/ and is the last modified file, that you can find if you sort by date. You should remove this file, if you can access the file system, either by 1) accessing the file system from an other Mac on the network, from ssh or by mounting a shared folders. 2) OR starting up in single user mode (or safe mode) 3) OR at last resort: reinstalling the OS above the existing install, which will keep your existing profiles, but remove the system modified files.
My wife has a three-year old iBook G4 and yesterday while she was doing some work, the screen just went black. By the time she brought it to me the machine was shut down. I hit the power button and it started to boot up, but about five seconds later it shut itself down again.
I kept playing with it and I was able to get back in to OS X and I played with it for a few minutes and all seemed fine. I then shut the screen and put it to sleep, then when I tried to wake it back up it shut itself down once again.
After a few more tries of getting it back in to the OS I was able to get all her files off the hard drive, but the problem is still there.
My guess is that it's the logic board, but that's just a guess.
Just bought a used ibook G4 from ebay for my sister and was giving it the once-over. did a software update and installed 10.5.3 (no backup first!). It installed ok, but after restarting it just sits on a black screen and goes nowhere. It plays the on chimes and churns the DVD drive, but then nothing. BTW, the computer didn't come with any installation discs
I was using my ibook just now, when suddenly, the screen went black, as if it were sleeping. I don't know if it was sleeping, but it would not wake up. I turned it off, and tried to turn it back on. But when it comes on, I just hear the fan. The apple logo does not light up. I'm not sure what's wrong.
I have an apple iBook that I bought in 2001 (yeah, its old but then Mac's are suppose to be immortal!). Lately, I have started to have a particular problem as in the screen goes black when I switch on the machine. It's not completely blank as I can see the back ground but not enough to use the computer. I have to manually adjust the screen by getting is back and forth close to the keyboard till I see the screen brightly. When I let go the screen it again turns black.
More recently even this has stopped working and when I wake my my computer first thing in the morning it refuses to show a bright screen. And I have to wait for a couple of hours for the machine to warm up and then after fiddling with the screen it finally allows me to watch a normal looking bright monitor. I am quite fed up. Am planning to show it to an Apple authorized service provider.
I'll keep it brief as possible. My iBook was crashing alot with the black screen saying "you need to restart your computer". I did a disc utillity permissions verify and repair and erased the hard drive. Next I started to reboot Tiger with the discs that came with the machine. It seemed to load everything up fine until the little movie came on about Mac OSX. The black screen came back on. When I rebooted I got the grey screen ( I think it's called the single user screen) where it says "Welcome to Open Frimware, the system time and date is:.... When i type "mac-boot" it flashes once and goes to an all blue screen with a folder in the center with a question mark on it. One more detail: on the very top of the firmware screen it says: Illegal instruction at %SRR0: ff85e778 %SRR1: 0008 1000
