Software :: Powerbook Screen Black After Rebooting?
Apr 24, 2009
I gave my Powerbook 15" G4 screen a wipe and after rebooting it has gone very dark. There is still an image there but I need a torch to see it. I've tried the brightness controls and rebooting several times but it is still the same. Is there anything else I can try before taking it to a Mac repairer.
recently my powerbook g4 has been doing some funny things. ..--Sometimes it won't turn on when pressing the button but eventually it will. --The computer would not book up earlier and would just stay on a white screen, like the white screen you normally get when booting but without the apple logo.--When my computer eventually booted it worked for a couple of mins and then the screen went a tinted black colour and a box came up in the middle of the screen saying i need to reboot (the box had a power logo for the background)--Then i rebooted and as i was rebooting a black screen came up with lots of writing in white. A bit like on a windows pc.
I've got an older 15" powerbook running Mac OS X 10.3.9 (i think). Lately my computer screen randomly turns itself off, the whole think going black, like it was asleep or off, but the computer keeps running just fine. Like i might have itunes playing or be burning a disc and that goes on just fine. The computer itself stays running. What I've been doing is putting the computer to sleep by closing the notebook, letting it rest for a few seconds and turning it back on by opening it back out. This fixes the problem for anywhere from 5 seconds to indefinitely, until it happens again. Lately its been happening more. The computer is 4 years old, but the model itself, probably 5.
It's a PowerBook G4, 15" model A1046, and this is what's going on.
Powers on, checks combo drive, gongs, no flickering or lighting on screen, period.
Tried a PRAM reset several times but it NEVER gongs a second time. I tried booting to Open Firmware and typing mac-boot, blind, but nothing. The keyboard clearly works, as the caps lock light works.
The hard drive spins up, the fans run at normal speeds, so everything else is clearly functional.
My MAC powerbook was working fine yesterday! I shut it down last night and when I tried to boot it up this morning I get: the booting "sound" and the grey screen after which the screen turns to black and in the top left-hand corner
I have this powerbook from 2005 and no problems up to now..ohhh no!
A couple of days ago started to occasionally make a clank clank noise and getting stacked on the spinning colour circle, only manual restart would do it.
Thought it might be the hard disk as it is a bit old and i never replaced anything on it, shacked it and a noise of something loose would happen, so i thought of opening it up and see if i could reattach anything loose....anyway i started unscrewing following instructions, couldn't get memory out...every screw seems different and so i gave up, put it all back together, praying that the screws are all in their right places and hey, now it wont even start, not a loose sound when shaken though, but not a bip not a light, black screen, nothing...only sign of life is the green light under the num block key and the capitals arrow also starts light
I was just using my powerbook G4 12" when it "clicked", the screen went black and it will not respond. the power cable light is on, and I've tried another battery, but it does not turn on! the little light on the latch button that glows usually, is not on. What has happened to my Powerbook????! I don't have applecare but I imagine I will be calling Apple this morning unless someone can help here
I own a MacPro1,1 that has a Geforce 7300 GT running on it. That video card comes with one Dual-Link DVI port, and anonther that is Single-Link. I just bought a Dell 30" 3008WFP monitor that has a max resolution of 2560x1900.
When I first connected, it worked great. I was getting the max res; life was good. Then I started getting this random green fuzzy screen that would come and go at whim. I couldn't reproduce it, and worse was I have not figured out a way to get rid of it. Early on, just unplugging and replugging in the cable worked. Then that stopped working. Rebooting stopped working. Once i was able to get the green to go away by powering down the display and powering it back up. Yes, totally random.
Here are some more facts:
1. Setting a lower resolution doesn't rid me of the green fuzz effect.
2. If i connect to the same monitor using the single-link DVI port, everything works great, but only reaches 1920X1600 (as expected).
3. Connecting to different monitor using the Dual-Link DVI port works fine, albeit that the other monitor has a lesser max resolution.
4. I'm running Snow Leopard 10.6.3 and I have all my software updates in place.
5. I've attached a screenshot of what this looks like.
Just realized that Apple is selling the black MacBook for the same price as the 12" PB before it was discontinued ($1499). Considering the PB was aluminum, no wonder Apple is making so much money...
I've got a friend with a 17" PowerBook G4 that's suddenly started displaying a vertical strip of black lines about 2" wide. Any idea what's causing the problem? I've seen plenty of pictures of PowerBooks with pixel-wide strips of a single color, but none that show black lines. Something else to note is that the problem area is displaying a shadow of the previous window that was there (ghosting).
He's tried all the usual, from rebooting to rubbing the problem area to pressing the metal strip above the keyboard to try and reseat the ribbon cable.
I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new.
That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts.
I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?
I was trying to install Windows XP Pro, but for some reason the it wasn't showing another HDD to install Windows on. So I quit the install, and restarted my computer. Now all that happens is the normal grey screen appears (with no Apple logo), then it goes to a black screen and has the blinking cursor (Kinda like DOS).
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.
I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?
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!
As the headline says the right half of the screen turns black when watching video content in iTunes on full screen. I can see the whole picture when moving the mouse a little but as soon as the navigation bar disappears the right half of the picture disappears too. It does not matter what source it is. Both podcasts and movies work (or do not work) the same.
The problem doesn't occur for other player (VLC, XBMC etc.).
I have the latest OS (10.9.4) and iTunes (11.4). The computer is MBP 13-inch retina, late 2012 if it matters.
Info: MacBook Pro (Retina, 13-inch, Late 2012), OS X Mavericks (10.9.4)
I've had my mac for about three years now and everything was working fine. After I installed lion, I notice that this started to happen. I don't lose any of my information though when it does that. It just goes into a sleep mode I guess? Anyways, is this a feature from the lion update? Something standard?
New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.
My macbook pro just has a black screen with a small coloured circle on the right of the screen. It is frozen and wont respond to turning it off or on. It is plugged into mains power.
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.
After an update(I think) I can no longer get into my computer. When turned on I get the apple logo then a grey screen that turns to black but the curser is active . Then there is no more progress to the startup screen
Computer starts (keyboard lit, music plays, caps lock light on), but no screen. I need to open and close 2 - 30 times before the screen will turn on. Once on, the computer works perfectly. I've tried PRAM and safemode reset.
I restarted and nothing. Still dim. I can barely, barely see things like if I hit expose, I can see shifting rectangles.
Also, I've been having this issue where the keyboard mostly stopped working -- if I hit kjjh, it'll come up as 3443 or something. It's usually fixed with a restart.
I have it covered by a year of applecare until feb 24, 2007 -- but I haven't registered it yet. Should I register and then call apple or what?
This comes at a REALLY bad time. I have design projects coming up everywhere and of course, despite my $250 external hard drive, i haven't been backing things up because I'm an idiot.
Can I hook it up to a external monitor just to make a backup of my hard drive?
