PowerPC :: LCD Screen Turning Red In Corners?

Sep 22, 2010

I wanted to fix this hardware problem with my iMac G4 20". Basically the LCD screen has a redish tint in the corners, only really visible when displaying something bright/white. Also, when looking at the screen from an angle when displaying a black image, it looks completely red. What's the fault here? Is it the panel itself or the backlight?

PowerPC :: IBook G4 Booting - Gray Screen With Apple Turning Gear Comes On Start Up

Dec 30, 2008

A friend of mine brought over his 14" iBook G4, 1.33GHz, 60GB HDD and 1.25 GB RAM. The problem with it is that upon start-up, the grey screen with the apple/turning gear comes up, then after a few moments a blue screen will appear, though no box showing the start-up process. I've run a few basic diagnostics on this, including the lovely disk utility (which did nothing), I've run fsck, zapped the PRAM, etc, no success as of yet. At one point, I received a screen with alternating folders, one showing the smiley mac face, the other folder with a flashing "?". I cannot replicate this for the life of me. I have attempted to acquire files via TDM, though am not able to see the hard drive despite using 2 different laptops. Possibly the firewire cable itself is spent, though it's brand new! Here is where I become increasingly frustrated: I ask my friend for the boot disks as the ones for my own 12" iBook don't work (for whatever reason). He tells me that he loaded Leopard this summer (currently running 10.5.2, no updates loaded since), then proceeds to bring over boot discs for a MacBook...:headdesk: To begin with, it seemed like the HDD was fried, however, after running disk utility (and not hearing any negative sounds), it does appear that the HDD is fine. I'm thinking a kernel panic, though not sure how to resolve these.

MacBook Pro :: Expose / Space / Screen Corners Stop Working

Aug 29, 2010

I just bought a Macbook Pro 15" i7; the only problem I've had with it is this: every now and then my Expose/Space/Screen Corners stop working, and the only solution I can find is to just restart my computer (which thanks to the i7 is only about 20 seconds anyway ). Does anyone here have any advice on this?

OS X :: IMac IC2D (plastic, Not Aluminium) Screen With (dark Corners)?

Feb 13, 2009

I have a question (whoa). I have an iMac Dual Core, bought in mid-2007 (it's the White Plastic version, not the newer Aluminium with the glass-display).

For some time now I had some dark spots, kind of shadow like in the bottom left corner. I wasn't bothered too much by them, but they got bigger, and now I have these in all of the corners except the bottom right one.

Anyone got any ideas how to get rid of them? (no, no three-year guarantee plan ... stupid me), or if not if it'd mean to replace the whole display or if it's just some cleaning (I talk money-wise here ...)

I attach two not-so-good pictures (the background is plain-white and the image is a bit enhanced ...) so you guys can see what I mean.

PowerPC :: EMAC Leaked "paste" And Now Both Bottom Corners Of Monitor Discolored

Jan 1, 2009

my firends eMAC leaked some "paste" like fluid (came home to it that way) which removed the finish from the desk it was sitting on. Now both bottom corners of the monitor are discoloured (purple and green i believe, left and right respectivley).... is the fluid harmful...ie: is it mercury? or is it simply the coolant? is the coolant harmful? He said there was a few ounces of the stuff under the machine on the desk. Just curious of hazards etc, and if its a sign of a new machine in his future?

PowerPC :: G4 Not Turning On

May 19, 2008

I have an old powermac G4 dual 1.42 the other day I decided to power it up to update it and it would not turn on. I push the power button it lights briefly and goes out. The light stays on if I hold the button down. The fan does not come on nor any noise from inside the case, etc. I have reset the pram, that little button, and I have replaced the battery, I have searched for the problem but nothing seems to fit my exact case. It's not my main computer and I am no where near an apple store and I'd rather fix the problem myself instead of paying an arm and leg for apple to repair it.

PowerPC :: IBook G4 Not Turning On

Jan 2, 2007

I have a 12" 1.33Ghz iBook G4 that does not respond when I try to turn it on. Every now and then I can hear the hard drives spin up but after that nothing happens. I've tried to make sure the problem wasn't being caused by my AC adaptor and battery and they seem to be fine. I even tried to remove my third party Crucial 1GB stick of RAM and it still won't work. Is there anything else I can try before I head over to the nearest Apple store?

PowerPC :: G5 Not Turning On Only Red Light Shown?

Nov 30, 2010

Up until recently my PowerMac G5 has performed as it should for a computer its age. About two nights ago it shut itself down and I haven't been able to turn it on since. Power does cycle through the unit because all the fans will either cycle once or twice, or at the very least they will twitch. And now there's a tiny red LED on the motherboard and behind the power button that lights up whenever I try to power on the computer. I'm at a loss for where I need to go from here, though I feel rather certain that my computer has simply passed on. It's an original 2004 1.6 ghz single processor PowerMac G5, serial number unknown, since I can't turn it on.

PowerPC :: IBook Turning Off At 0% Battery

Mar 6, 2007

My iBook used to come up with an alert that it was using reserve power, and then automatically go to sleep, so I could wake it as soon as I plugged it in. Now, there is no warning, if it gets to 0% it turns off, NOT sleeps but turns completely off without shutting down. This means any unsaved work is lost etc, its not at all good. Can anyone tell me how to fix this? (I have Tiger, iBook 1.44Ghz, 1.25 RAM)

PowerPC :: Turning An IMac With LCD Into An Eternal Monitor

Nov 17, 2010

I have a first gen iMac 24 Intel with a dead logic board. However everything works in it. The screen, power supply, isite, speakers. appear to work fine. I got a MacBook Pro to replace it and I wanted to know if there is a way to turn the old iMac into something that is more like the Apple 24� display, even if I need to do electronics work in it.

I am in IT and have access to a lot of dead stuff I can scavenge for parts. I am also an electronic technician, so I should be able to do this. I just don�t know what I need to do.

Hunting down info on this topic has come with that there are controller issues. If I can pull a controller out of another dead LCD display that I happen to have, I can see it working. I can even see the possibility of adding the electronics from a USB hub to pipe USB functions over a DVI cable. And get the iSite and speakers working.

IMac :: Screen Turning On And Off At Random

Aug 7, 2009

I have a 24" 2007 iMac, the first aluminum ones, 4Gb of Ram and a recently upgraded HD to 1Tb (from a 320Gb failed drive). Recently, I have noticed that under some active usage, such as playing World of Warcraft or Excel, the screen will start to turn completely off for 10 seconds, and then back on for 10 seconds. It will continue to do this for about 3 hours, turning on and off every few seconds or 15 seconds. It will mostly turn completely dark but would also sometimes flicker. The curious thing, is that if I continue to keep playing, the screen would cease doing this after about 3 hours and then be completely normal and fine, but the next night.

The symptoms would repeat itself, and would consistently go away after active usage (3 hours or so). Imagine this, as if the iMac itself needs to be "warmed up" for 3 hours before normal usage. It would also appear that if I hit the machine (or tap it), this may sometimes bring a dark screen back to life for a few seconds. I plan to bring it to support, but I just want to get some ideas from you guys as to what this can possibly be.

Some of my guesses:
1) It cannot be software as physically hitting it or my dog barking would affect the rate and speed of the random turn Ons and Offs.
2) It could be a loose connector from my recent transportation of it while upgrading my HD, but then why would it become normal after 3 hours of usage?
3) Maybe something to do with RAM or video RAM? It is faulty, and thus only prolong heavy usage would "run it in" for the session? After not using it for a while, it goes back to its failed state?

MacBook Pro :: Nothing On Screen But Computer Still Turning On?

Jul 1, 2010

I have an older generation Macbook Pro (the all-silver two-part body style that came out before the current Macbook Pro) that I got approximately two years ago. I do use it quite heavily but have always taken good care of it.

About a week ago, I was using it as normal, then put it into sleep mode and went away from it for an hour. When I came back to it and opened it back up, there was nothing. I tried closing it and re-opening it, still nothing. I did a hard shut-down by pressing the power button until the power light went off, and then restarted it. Even though the computer turned on and the power light lit up, the screen remained black, and the Apple symbol on the lid remained unlit.

I called technical support and they ran me through a list of fixes including holding several keys down and turning on the computer, etc. None of them did anything to the computer as far as I was able to tell. I was not getting any sound, either--whether from having my computer muted or from the computer not working, I'm not sure.

I then tried putting the MBP into Target Disk Mode by connecting it to my sister's MB--no response. Still, the screen remained black on the MBP and no icon for the MBP Disk appeared on the MB. Even though the computer powers up, runs the fan and everything, it appears to be dead for all intents and purposes.

I have two main questions here:

1) What is going on here? Is it as simple as a screen problem, or has my motherboard gone? This is the very first problem I've ever had with my MBP; nothing has led up to this.

2) Is there any chance that my files are safe? I'm currently on vacation and backed up my files prior to leaving, but have done a lot of work since being on the trip and am not too keen to lose what I've done.

MacBook :: Turning Screen Into External Monitor

Dec 19, 2009

My 2006 mMcBook is dead and parted out. I still have the case and screen, but no HD, RAM, battery, or working logic board. How can I take the screen and make myself an external monitor out of it? I am presuming it's possible. I can solder a little and I love messing with parts from radio shack. So, has anyone heard of this? I tried googling it but couldn't find any search terms that brought me what I wanted.

Basically, I want to convert the video cable to DVI or even better, Display Port, and then figure out how to solder in a power source to just plug into a wall (since I'm assuming it'd be too big of a job to have it powered off of the FW800 or USB from the macbook pro). Is this possible? Since the computer is dead and gone, it won't hurt to experiment. Anyone have any links or guides to this?

MacBook :: Screen Brightness: Randomly Turning Off?

May 14, 2012

1. Screen Brightness is on.  Desktop functioning as normal, according to the brightness set.

2. Randomly, the entire screen brightness will switch 'off' - but not go to sleep - it is set at the brightness level, as if you would have turned it all the way down manually. Automatically, my screen goes from:

3. After clicking the brightness button on the screen - when I look closely - the brightness control is set at its previous level, but the screen is not at that brightness! darkest screen (above, right) + brightness settings up    

4. In order to solve the issue, I have to hold down the minimize brightness button and then turn it back up, from the lowest setting. This only works about one in five times. All other times, the screen briefly flashes and then goes dark again.

MacBook Pro :: Screen Turning Off Randomly, Cannot Turn Back On

Apr 9, 2012

screen goes black, laptop seems to have not turned off but nothing can turn the screen on.  seems fine after a reboot but problem recurs at some random future inconvenient point in time.  problem is annoyingly inconsistent - it will occur at random (no discoverable software or hardware conjunctions), sometimes around once weekly, sometimes less frequently.  have already had it in a mac repair, said they fixed it, something to do with graphics card firmware.

Every now and then, the screen stays blue for about 20 seconds.

MacBook :: Screen Intermittently Turning Itself Off And On / Sleep And Wake Occurring

Aug 8, 2010

I bought a new unibody Macbook around 4-5 months ago and I've generally been very impressed with it. It's my first Mac and considering all the problems I'd had before with Windows PC's, it's quite a relief.Anyway, here's the issue. When hooked up to my 24 inch Dell monitor there are numerous problems. Originally it just started with the screen intermittently turning itself off and on, and there being a sleep/wake issue. I did some research then and discovered that this was by no means a problem confined to me. Knowing this I was prepared to wait until Apple fixed it with a firmware update or something, as the problem was annoying but not devastating.

However since then the problem has got significantly worse. Not only are the screen flickering, sleep wake/issues occuring much more frequently, but there are other problems. For instance, the menu bar and the dock sometimes fail to show, and I've been having a very weird problem with the Logitech mouse I use. Even though I can move the cursor generally I can't click, and when I can, only the right mouse button works.The same is true with the trackpad, so it's not a problem with the mouse.

When these problems occur the system generally seems to be very slow. I've checked the 'activity monitor' and the use of 'system memory' seems to be very high. For instance, at the moment (I'm using my Macbook by itself) I'm running a few applications (Mail, iCal etc.) and I've got 1.09 gb of free memory. Last night I was running exactly the same applications and I must have had less than 0.4 gb of free memory. The pageout numbers were fairly high as well.

It's strange because when disconnected from the external monitor the Macbook seems to work seamlessly. I just don't understand how some of the problems I've experienced (such as the mouse issue) can arise from problems relating to the external monitor setup. What do you think? Should I be worried that these issues are perhaps indicative of a greater problem? Either way, the problems are becoming hard to deal with. Very disappointing.
