Laptops :: Fix IBook Blank Screen With Heatsink Fin
Jan 16, 2009
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?

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 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 just had a quick power interruption for about a second while I was using my laptop. The laptop shut down and will not boot up. The screen is black. Any ideas on what is the problem?

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.

I have a MAC IBook (800 MHz 32VRAM) ibook and when I turned it on this morning I got a blank screen. I tried turning it off and on several times to no avail. I know the computer is on because when I touch the sound button (F5) I could hear the noise, but I have just a blank screen. I am assuming its a monitor problem or did I touch a function(s) key by mistake and it blanked the screen.

I do computer repair and have run into an issue that I cannot figure out. My customer has an iBook G4 and the screen will stay blank as if it's off even when the power button is pressed. I've tried turning it on only on AC power; I've tried Cmd-Option-P-R; I have tried applying pressure in various places. When I asked my customer about what was happening when the issue started, he said his kids were on it, the battery died and the next time he tried to boot it up, it wouldn't work. It gave him neither errors nor lines on the screen; it just wouldn't turn on. Now the strange thing is everything else works. The fans spin, the hard drive spins, and it gives the startup sound. I tried to see if maybe the brightness was to low but that didn't work either.

I just got this iBook 12" in the mail been to a mac shop before I bought it where the owner was told the screen had died. Motherboard was said to be Ok by the repairer. I replaced the screen with a know working one and the screen was dead. Then after the fiddle of pulling it apart again wondered if I could use the hard drive on another ibook. The hard drive I put in another iBook which loaded up fine with display. Later I tried again but it was a dead screen? Is it that both ibooks have faulty motherboards? Motherboard determines a display? Or could it be the display module? What else could cause dead screen? Cables good.

I have had my g4 for about two years and all of a sudden the thing decided that it's not going to turn on anymore. Power is getting to the machine and a certain amount of whirring is heard but not the signature! as it starts. The screen remains blank and would stay like that all night if I let it. The only thing I did differently before this appeared was to take it to work in a different bag a few times. Rucksack before, Side bag (more vibration).

I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.

I have an iBook (OSX 10.3.9)that's been great for the last couple of years. However the last week or so the screen goes dark for no apparent reason. You can still see through enough to fiddle around and hit shut down...and after it shuts down, and I restart it...it seems normal...that is until the next time. It's happened about 4 times in the last three days. A couple of times on battery and once plugged in I think. It's like it goes to sleep but you can't hit the space bar to wake up. Also seems like maybe an energy saving deal gone awry.
Now for info that may be pertinent: I dropped this laptop(in it's case) about a year ago. Holy crap..all docs would only read in magenta. No black no color only magenta and a "photograph negative" looking image for background or any graphic. I was sure it was dead duck and fried but kept trying it periodically. After about a month, after giving up...I turned it on and it was fine...as if nothing was wrong. Weirdest deal. It's been fine ever since.
I thought perhaps I was too lucky...and assume this may be a result of that fall.

my mother with her ibook g4. She lives next door in a side by side house and gets her internet from our dlink router. The signal seems to be working as my wife's laptop gets the internet in our house. My mother has a dlink booster in her house that seems to be getting the signal as its light is flickering which means it's working. Her ibook seems to be getting the signal as all bars on top are black. When trying safari or mail an error shows that the server can't be found.

I've got an iBook G4, 1.2 GHz, OS 10.4.11, 125 gb HD, 1.2 GB RAM, usual 32 MB vram.Thing is, the video speed isn't quite what it used to be. YouTube vids used to run just fine, about 2-3 years ago. Now, of course, it's choppy at best. Ditto Hulu and pretty much any other online video.
I seem to recall something from years and years ago, back in the Classic days, of how you could let the graphics use regular RAM to supplement the vram, something like that - the end result being that it would play smoother than before, kind of a speed bump for the video.

I have a 1.33 GHz PowerPC G4 (1.2) version 10.4.11 ibook that was purchased in May or June of 2005. Lately, out of the blue, the power chord has stopped working.
The light that indicates the computer is charging goes on for a second and then promptly turns off and stays off; the laptop is then running on battery power; it is almost dead.
When it tries to connect (before turning off) it makes a sound like a lightbulb that is flickering and trying not to die.
This could be an outlet problem, I suppose (I will have my dorm check on that), but think it might have gotten fried when I was home for christmas because our house has ancient outlets and I usually have to use the two prong adapter there.

I recently changed providers and started DSL. I have a modem with built-in wireless capabilities. Set it up for my desktop (wired) and all worked well. My son has an iBook G4 running 10.4.11 - same as my desktop. It has an Airport card in it so we figured he should be able to connect to the modem wirelessly. Set it up and it worked well for one day. Following day it would not connect.
I set up the wireless connection with WPA-PSK selected and channel 9 selected. Made sure the iBook was set the same. When prompted for the password we get an error message stating there is an "error" connecting to the modem. Using the set up assistant for the Airport card yielded no change.
Today we turned off the WPA-PSK and he can connect with no problem. I'm not entirely comfortable with WPA shut off. I read something that implied the password needs to be a certain length to work for some settings - notably WEP. I used an 8 character password for the PSK.

I have an old iBook that I just want to completely wipe clean and install windows XP on (I know...blaspheme). Before people start questioning why I would do such a thing...it's only because I need the laptop for DJing in which I have an external sound card that only works with Windows. The main problem is that the CD drive doesn't work so I am uncertain how to go about erasing my hard drive and installing XP via USB.

I have an old iBook G4 laptop and a newer iMac (OS 10.5.8). Since getting the iMac, I've neglected the laptop and so the info on it is old. I would like to synchronize these two computers and bring the laptop up to date with the iMac. Basically, I'd like to erase the laptop and then have it be a copy of the iMac. Given that I'm not very techie, how do I do this please?! And how long would it take? Thanks for any help.

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.
Info:
iMac (27-inch Mid 2011)

I got a Powerbook G4 12" from my cousin, and the hinge was all beat up. The screen wouldnt work, although it did turn on fine(fan running and HD clicking). So we took it apart, and found a broken wire in the hinge, and replaced it, and now it works. But, after using it for a while, the fan was on full blast, and wouldnt turn down. Since it was still apart, we took off the top, and the HD and heatsink were encredibly hot(i probably would have burned my finger if I kept it there long enough). I know that it will get a bit hot, but nothing should be running at that temperature. What could cause this?

I've been noticing quite a difference in the temperatures of the two so just now I tried something. Running 4 threads of yes > /dev/null for 10 minutes now, I have a CPU temp of 202F and a CPU Heatsink temp of 128F. Thats a difference of 74F now either the heatsink is losing 74F faster than it can build it or something is wrong with the transfer between the two.

I have been searching high and low for a alternative heatsink for a dual 1Ghz G4 CPU. I just got this chip off Ebay, but by dual heatsink, that works with a dual 533Mhz, won't fit. And I can't find anyone who is selling just the heatsink.

For the past couple of weeks I've noticed that my old white macbook is running hot, and browsing has been kind of slow. I don't see anything out of the ordinary in the processes, but Heatsink A is reading -1. Should I just pull the machine apart and see if something isn't connected anymore? I installed a 7200 RPM HD a few months ago, but this problem is more recent.
